I'm an average autocrosser who makes it to events 2-3 times per year. Feel free to ask any questions in the comments and I'll do my best to answer. Subscribe for more video's including some autocrossing as the season approaches! - Авто та транспорт
the way this is presented is hilarious basically like "wanna do that shit? Cool-street class."
I agree, SCCA needs to make it easier to get this information in a cut and dry form.
so...I am on the SCCA website for an hour and find nothing. I hop on UA-cam and find this guy with 58 subs as of now ( I subbed) and wonder why does this guy have so little subbs LOL.. Perfect Ian. This will help so many of us! Thanks!
Thanks for the sub Scenic. I thought it was ridiculous how little information SCCA provides for such a hot topic. Our local autocross group forums is 75% new people asking what class their car is in and moderators just snapping at them because they've answered the question so many times. Once I came across this "cheat sheet" SCCA provided I figured I'd make a quick video because I couldn't find one. Glad it has been able to help!
i printed out that cheat sheet you provided and will be taking it to our next meet and handing it out!
im still trying to figure out if i do a cat delete what class that would put me in. I have a stock RX8. In in C Street as of now. I want to delete my cat so i can pre mix. the SCCA thinks they are a secret society or something...
I'm pretty sure you can only touch the exhaust after the cat. (The stock cat can't be messed with in C Street.) Meaning, you could remove the mufflers and have straight pipe back, but the cat must remain untouched. I saw this a lot on WRX's running stock class, I mention them because they sounded pretty good with the muffler delete.
Oh I know it will change my class. Just not sure to what.
Hahaha you said exactly what I was think. I’m just trying drive my car around some dang cones
Good video, I get a headache everytime I look at the rulebook for classes.
I spent hours trying to figure this out on long stupid PDFs... Thanks for this video
Thanks for clearing everything up!
This was a ton of help, I greatly appreciate it
This video was amazingly informative and entertaining. thank you.
Street Prepared is the first class where you can have an engine swap due to the update/backdate rule.
Well shit I'm straight into Street modified with a swapped datsun, coilovers and glass hood...
Bouta get served lol, it's the datsun pickup lol.
Awesome ride! Just go out and have fun. I had a 280z many years ago. :)
This video should be viral. Great work dude
Super helpful as I start planning to get into autocross! Sub’d!
Just made 40 and finally doing what I have to do to get going with this and this was very helpful. Running on streets for years is easy. Rules... Not so much lol. Thanks.
Enjoyed the heck out of your video. My autocross days began and ended when I bought a new Pinto in 1973. I went from the dealer to a wheel shop and purchased Cragar ss wheels ( 1/2” wider than stock wheels) entered an autocross that weekend and BAM!…. D Modified Production. Still had fun. somehow finished 7th out of 14 cars. Must have been the Radials.
awesome video man thanks
This really helped!!! Now I know that my car is Street Modified!
I plan on racing once I get some cash in the bank and this has been very useful
I especially enjoyed that you’re holding a Lite through the video, a la Julian from TPB. Great informative video to boot! Cheers!
Very cool vid, I like your RS!
Thanks, i know 5 years theres gonna be a grain of salt difference, went from touring quickly to modified 😂😂 full suspension and weight saving modifications
you're a saint
Went to school on your video. Good job.
Good video! Thanks
great video!
love the sarcasm and beer haha, great video though. Wish i would have watched this before going through the rule book
Billy Hayden kudos for doing your homework. I was the rookie chief at a loca club for a while and this topic was always a mystery so I wanted to make this video to help those getting into AutoX. It can be intimidating.
This is great.
I beat my head into the rules and knit picked my build to death; only to find this breakdown lol
Whoo hoo 100th subscriber!!!
Ruben Gonzalez thank you!!! I’ll be releasing a special video soon! Stay tuned!
Building a '91 Miata for AutoX and had no idea about modifications and how it affects classes! This video helped a ton! Going for a ESP (E Street Prepared) build. Thank you!
Thank you for the vid. Great job! hard to think with a clutch coilovers and pads and rotors puts me in street prepared. Guess i have more room to grow.
I agree... a bummer that something like an upgraded clutch moves you into a higher class. I don't consider that much of a competitive advantage but rules are rules. Good luck this season!
thanks man!
wow. I guess I'm not running in STU anymore lol. Time to figure out what class I'm in
Good video
thank you. this helped a lot. now what are all those letters for each class for?
I got *DS* for my stock '22 WRX
Brihhh you kinda sound like bobs bergers!! 🖤
Great so by the SCCA 380 page book of rules for 2021... my acr neon falls under street modified fwd.. great first track day and im already in top class for street class 😂🤣 im so screwed hahahha
thanks
KInda sad it takes 10 minutes to explain classes now. I also figured that it would take more than one beer....in fact, I was surprised that you didn't move to liquor.....
... and I left out some classes. That's what you get with a 250 page rule book, this was hard to make under 10 minutes, I realize why this video doesn't really exist... I wouldn't be surprised if classing alone scares people away.
Ian G Ent. Especially with classless guys like us.....
Love it. Especially while sipping on some Miller Lite;)
Guess I go straight to street modified when I'm done restoring my 79 El Camino from high school. Basically the only thing I'm reusing from the suspension are the front control arms.. not even counting engine and trans lol
Nashvilleoutlaw.. There is a unlimited Vintage Street Muscle car class..CAM-T
well damn 🤣 ill be in street modified because of swapping my transmission
Great video! I have a 2021 Mazda MX-5 Miata with BBS/Brembos package, soft top, Club trim with Manual trans, nothing modified, which class is it? CS? Thanks!
Oh no my car is a 100% stock automatic Impreza Outback Sport but I put on an Anti-Dive Kit because the bushings were completely toast… looks like I’m Street Touring in my first event 😆
Damn my completely stock V6 camaro with an aftermarket lip/spoiler falls into the prepared category 😂
Where do straight up race cars fit? Modified? I have an H production Austin Healey Bugeye Sprite that I want to run in autocross next summer (2022).
Do you have any videos of you running your RS I have a 2018 I am running.
Good video, Main thing being ,The Class Briefing Sheet is very helpful.Gives you a good base line of what Category of class you should be in.I hand it out at our events.The new drivers are happy to get it.The ones that got a little lost looking in the classing book. They liked it even more..Glade competition manager Doug Gill put it together. I asked if he could do something like this years ago. One tech error in video.Big wing doesn't put you in Street Prepared. It moves you to Street Modified.SP only allows adding 10inch flat rear spoiler.They are a few lines apart on the briefing sheet..:) It might of been the beer. Also like it was stated earlier.Street Prepared does allow limited engine swap with in gen. I took the 12a out of my FB RX7 for the 13b 6port in the 84-85 for C-Street Prepared.
One line that might confuse people on the Street Prepared Briefing sheet bullet points."You can cut or replace fenders for wider tires".Fender have to be what was available stock.Stock fender options are possible I guess.. What you can do is.Cut fender and add fender flare.Replacing complete fender is more likely SM.
From what I can tell, I’d be street modified. I didn’t catch you mentioning ethanol though
“If you fall into that ok”… cool story bro
So my elantra is an HS lol good to know
Soooo what if you have a base mustang gt but put on the same brakes and suspension components as the performance pack? Technically still same parts from factory. Is that a gray area or are you moving up a class
So if I take my stock 74 automatic transmission pinto and put in a 5 speed I'm in street modified?
Can I remove every seat except driver in street stock? I guess not, I should just go for street touring.
Do these rules apply to you if you want to run circuit ?
Okay??? So I'm street, but what are the sub categories a through h??
question that may sound dumb; but if i have a gti but it has r32 body kit on it which class would that be? considering the r32 model comes from the factory
I put a 2016 Maxima engine (VQ35DE) in my 2004 Maxima (also a VQ35DE) for reliability purposes. The timing is different so it requires cam sensor inverters for the intake, and additional wiring and cam sensor inverters for the exhaust. The ECU also needs to be tuned for the intake manifold or the car will lose a ton of midrange power. How badly am I getting screwed here? 🤣
Something I'm dealing with a lot.Coilovers are not allow 100% in Street Touring,Street Prepared,Street Modified.If your car didn't come stock with a Spring over Shock.Then you can't have a coilover.Many cars can have Coilover in front but not rear.Examples Mustangs,Nissan 350Z and 370z,G35.G37.Fiat Aba etc. Relocation the rear spring to a different location moves you to a Prepared class .Not Street Prepared but PREPARED stripped down of interior & lights missing windows classing
I see my Honda Fit is Street H, but What are the street subcategories based on? A thru H? Is it based on PAX? Is that information available anywhere?
I have a 2021 Mercedes Benz A220. Everything on it is stock though. What race class is this car in?
Imagine changing the fuel injectors to your car and end up in Street Modified with 911s and GTRs 😂
Man I got a big ducktail and flares on my stock na6 miata I'm gonna get tailed lol
83 firebird umi equipped
Street touring engine mods
Stock engine so that sucks
Did I miss you mention test pipes? It’s a 370z and it sounds like it would be ASP, can someone confirm?
Say I show up in a '70s NASCAR stock car, what class am I in?
99 dodge stratus what class am I lol going to rear do suspension with good parts and add some performance coils and maybe intake .
Unmodded, all stratus in H Street. Suspension will automatically put you in a street touring class STS but you can only run up to 7.5 wheels and 225 tires. Suggest sticking with HS it's the slowest class so everyone you beat your the under dog. Swaybar good shocks and struts and Bridgestone re71r (the widest that will fit on oem width wheels ) and have fun
My car is not quite on the list you think you can help classified it?
roll cages? any/all classes?
How do they know what mods have been done? They plug it in?
Can I strip my interior and not end up in the higher class?
Question; if I replace the 2 piece steel drive shaft for an aluminium one piece on my 2013 BRZ, will I stay in STX?
Tenaciousdomi I would guess a drivetrain upgrade like that would put you into Street Modified. Would be best to confirm with your local autocross group though.
Sudden realization that my car would get queued in street modified after only 700 dollars of mods
I have just dug out a old 75 280z that has been sitting for 20 years but it has been gutted, has a roll cage, fuel cell, air cooled break pipes. It was just missing a fuel rail and i put a modern one on and to my surprise it started right up. So i was thinking about racing it but i dont trust the drums in the back. I have no idea what class I am in now probably street modified but I would like to race what ever class i can but if i do a break swap what would that mean? where would that put me?
I had a 280z as well. Excellent car. I believe all those modifications would put you into Street modified as well (brakes upgrade or not). Remember if you're wondering there's typically someone at your local region you can ask that will assist with classing your car as well. Have fun in that car!
Hi, i am new to this and am tryna learn. On your listed link of street class cars, i couldnt find my bmw 325i sedan 04. Does this mean this car isnt allowed? Sorry if I misunderstood
Zaareb Raja It looks like your car if stock falls under GS. 3 Series, E46 non-M
I am assuming adding a turbo to am engine that was NA from factory means Street Modified, is this correct?
i think so. also if you do an upgraded turbo probably the same thing
i cannot find my car in street touring acura tl
im still a little confused. i have a 2015 328i with catless downpipe, chargepipe, fmic, axleback, turbo inlet, cai, tune, and have an aftermarket trunk spoiler. what would my class be?
Sounds like a Street Modified car to me. I'd check the Street Modified section of the rules to make sure you car fits.
STF is no longer there, but there is a STH, cars not the same though
kaosncompany77 I will update for the 2019 year soon. 👍🏻
Any idea what SGT is?
So I know technically any body parts would put you in prepared class, but is it the type of thing where they give you some wiggle room, or is it set in stone? Asking because one of my friends has aftermarket canards, but everything else in the car is stock
I was wondering this as well, are there rules against canards on street prepared cars?
"street clas- ... You're still in street class."
How would they enforce all these rules? They would need an expert on every car to be able to recognize stuff that isn't stock. Like an ecu mod. Or some cars that have supercharged and non supercharged models, but maybe you put on a factory looking supercharger. Or maybe you got better sway bars from a different car, etc.
UMM I have a Legends car was wounding about it lol
I have an Aston Martin V8 Vantage (Convertible) with no modifications. I can't seem to find any Aston Martin on the lists? Which class am I in?
I don't see this on the sheet either. I would ask your local club what class they want you to run in. My guess would be AS.
Damn. .. I think I'm street modified 🤣
The rule book link doesn't seem to work.
2017 Lexus IS300 F sport which class am I in?
THE VANILLA COLLECTION it appears you would be D Street.
I guess im street class. but the question is, which category in street class?
I blindly tried stu and absolutely got dusted
For some reason the link isn’t working or is that just me?
What class for Meth injection or E85?
If your car was a flex-fuel vehicle from the factory you can use e85 in street and street touring classes. If it was a conversion it goes to Prepared or Modified.
Below is the Fuel rule from the 2019 draft.
"3.6 FUEL
A. Street and Street Touring® category vehicles will use fuel which is “Federally approved for use on public highways,” and which does not exceed an octane rating of 93 AKI (Anti-Knock Index = [R+M]/2) with an allowed variance up to +0.9. Fuel may not exceed 15% ethanol (E15). This includes the pump fuel known as E85, but does not allow racing- type fuels which are available at service station pumps. Fuels comprised of more than 15% ethanol may only be used when specified by the manufacturer (e.g., in the owner’s manual for flex-fuel vehicles).
B. In addition to fuels which are allowed by Section 3.6.A, Street Prepared, Street Modified, Prepared, and Modified category vehicles may use die- sel fuel, any grade of gasoline, or any gasoline/ethanol blend. Gaso- lines consist entirely of hydrocarbon compounds. Gasoline may contain antioxidants, metal deactivators, corrosion inhibitors, and lead alkyl compounds such as tetraethyl lead. Methanol is prohibited; other oxy-

Massive amounts of obscure preparation limits, diluting competition since 1978.
I'm preparing to talk my girlfriend into it as a family hobby. Any advice as a family outing?
Michael Boyle this is a great family hobby! My wife co-drives with me periodically. Just be prepared to switch your numbers between runs and it’s always fun to ride along with each other.
what about lowering springs?
Lowering springs will put you into a street touring class.
Lowering springs would put you into a street touring class. (And be allowed in any modified or prepared class as well.)
They have a few items listed that are purely cosmetic for rallyx. A removable steering wheel for example. Thats a dumb rule.
My Fiat 500 is ineligible. Does this mean that the car isn’t allowed at all, or that it can’t compete for times? The Abarth version of the same car is not ineligible, so it must not be for safety reasons.
Keith Petersen you would have to reach out to your local club. It’s likely that you can’t compete due to roll over factor. SCCA has a formula to determine stabilization factor based on cars height/width. Same reason Most SUVs can’t compete. There have been Abarths rolling over as well at autoX (google it). So they can be strict.
Thank you. Will do. It just seemed odd that the Abarth version was OK but the standard was not.
@@critterIMHO It says ineligible for STREET=stock Category for being unstable. You can change it and lower it and run it in a improved class like Street Touring or Street Prepared. example Subaru Forester is also listed as unstable for stock class. but it is listed in F-Street Prepared
that sucks swapped Hondas get thrown into street modified
How would they know if the ECU has been flashed?
Andrew Rout, from my expeierience at local events there’s just a level of integrity most have. If you want to “cheat” you’re only cheating yourself. Typically a clubs prizes are a coozie or cup or something small. There’s really no reason to cheat. If you suspect someone is cheating you can raise this with your club. I often see rookies “cheating” but because classing is so confusing (thanks SCCA) it’s almost always not on purpose. At a national level they impound your cars and inspect them. You can also protest other cars if you suspect something is not by the book, this is fairly rare. If you flashed your ECU run the street class you fall into or flash it back and run stock would be my suggestion.
@@iangent.961 Got it; wasn't suggesting I wanted to cheat; I'm just new to all of this and wondering about the inspections they do. I'm sure at some point I'll want to be competitive against others, for now though, just looking to have fun and find the limits of my car.
Andrew Rout perfect reason to autocross!
So I have a stock car with an intake and exhaust. However pretty much the whole interior is gutted. I haven't autocrossed it yet. That still puts me in the street modified class?
Austin Evans that’s my understanding. We had a guy with a fairly stock car locally but he didn’t have his back seat in and that bumped him to SM.
@@iangent.961 That kinda sucks, I like my weight reduction lol
@@austinevans9365 If it's completely gutted you go to Prepared classing. Not Street Prepared but PREPARED Category. Street Modified is only removal of rear seat.
If i miss something and register in the wrong class, i fully expect to be disqualified, but are people going to be cool about it, or are they going to be dicks at the next event?
