This video gives viewers very specific telemetry numbers to look for while tuning. This method helps me produce very fast and consistent tunes for my cars. I hope this helps others!
The end of the video recaps each step of my tuning process.
Thanks for an actual guide instead of just reading the description the game gives in more words like other guides do. So frustrating how many people put up shitty guides that don't help.
That was a lot of information in 10 minutes. I will need to rewatch this a dozen times!
Thank you for looking out for the beginners in Forza.😀
I know this is an old vid but for camber, I found a video by Gallium that wisely points to the tire temperature (inside, middle, and outside) to tune camber such that the corner-exit temp of the outside tire is either even across the tire or (for the sake of tire wear) slightly cooler on the inside.
Downloaded this a few days ago and just rage quit spitting fire! They don't tell you anything really so thanks for this vid, I'll try one more time.
This is a big help, i heard about this video from a good friend of mine. Thanks a lot for making this. I'm doing this to my 69' nova, (Since it's my personal favorite car, might do this to my el camino as well), and it went from running 2:06.8 on Catalunya to 2:00.8. It still needs tiny adjustments, but the results are big.
kirbyowns14 Very happy my system helped you. I was tired of no one really making a system to get the car tuned in a cohesive way. All the youtubers have individual videos for each setting. Plus they leave things too vague.
If you want more info visit the forums post I provided in the video description. It has a few numbers and suggestions that I changed since this video was made.
Have fun racing!
this is a SOLID guide
Nice tutorial ;) Good base spring I use is (Max spring rate - Min spring rate x Weight bias in decimal of front and rear) Example, if it's 48% front, Max spring is 1142.8 and Min spring is 126.3. (1142.8 - 126.3 x .48/.52) = Front 487.9/ Rear 528.6 or as close to. Then adjust from there.
Thanks for the support! Glad you found a spring rate system that works for you!
Funny thing here is if the car has a front mounted engine and weighs around 1,400 - 1,200 I'll have have front tire psi at 38 - 45 at most with the rear 28 at lowest and 36.5 at highest it stops the car from sliding like the track has lube, I get better turn in speed as well
I forgot to mention that racing tires are better for it
Changing tire psi to compensate for the weight is something I never did! If it is as big of a change as you just described then this video should be updated to include that information. Very enlightening!
Correct, usually you want the front to be higher than the rear for better response and turn in. But I never thought about it due to engine usually being in the front.
Dang this is very informative!
My dad is probably going to get Forza, mainly for its split screen feature to race me. I'm not that good a driver, mainly because I never really played a racing game at the level I need to git gud(I have Gran Turismo 5 but I detest some of its design choices, Forza doesn't have this.)
Now this guide really helps me. It gives me some kind of guideline on how to tune, I'll just borrow my dad's laptop and practice in a relatively easy car with a good, premade, tune until I've got enough skill to tune something myself
Wow man, very impressive. I can tell that zonda is an absolute dream just by watching this. I reckon you're using a wheel instead of a controller based off of how smooth you drive through the longer corners. I've always been tuning by feel never felt the need to look at telemetry but this has opened my eyes ten fold. Thanks for this!
Just using a controller :)
Very informative. Thank you.
Bro i still don't understand your method i try it a couple of times and nothing
I don’t get how to use that spring formula I’m so confused
Here is a post made by users over a year ago that answers that question:

There is no possible way to get a negative number unless a mistake was made. Here is an example for you to see it working. 51% weight ratio, 500lb front springs ----> 500(1-0.51)/0.51=480.4lbs
or another example, lets make it extreme! 42% weight ratio, 200lbs front springs -----> 200(1-0.42)/0.42=276.2lbs
Hopefully this clears things up for you!

Thanks, you've been crystal clear now! ;-)
Love your vid. At around the 35 sec mark then again around 9:30 you take 2 corners with mid-corner oversteer. May wanna back off rear arb or up the front arb.
how can I get the front of the car to grip more on 4 wheel drive cars
This can depend on nearly every factor of your tune. Start by getting a good base tune, then look to adjust camber, toe, roll bars, aero force, and differential. Also consider your wheel sizes, and the cars weight distribution.
If you are confident the problem persists despite you having a good tune. Then look to remove traction from the rear to allow the car to slide evenly.
Lastly, I recommend watching this video. I take you through a tune and you can see and hear my explainations. It is long so check it out when you have a lot of free time. Maybe even tune your car in your game along with me.

I usually mess with the diff sending more power to the rear tires and heavy areo in front and thicker tires on the front.
Also watch allot of inital d
Ive had luck softening the front roll bar for understeer
Does anybody know a link to a tuning guide where they use metric system?
Bosmanneggie I have begun using the metric system since playing projects cars 2. Numbers so different take a moment to get used to. Luckily, the benchmarks I provide ex 0.7 compression etc don't change regardless of it being imperial vs metric. So this video should still provide the information you need to tune a car. If there are some conversions needed (such as springs then use Google to convert)
I maxed out front stiffness and it still goes over 0.75. I fiddled with Damping but you never mentioned it!!!
You are looking for the average numbers to be 0.75 compression. It will still go above those numbers, you just want it to be average. Put the video in slow motion and watch my example footage to see. Also, you are playing on a newer version of the game so things might be different. Also some cars are more difficult to tune than others and then you need to make sacrifices. This video goes really in depth and maybe it will help you further ua-cam.com/video/9v8NIX7iLiA/v-deo.html
I would recommend you not try to use your damping settings to control the compression, damping is meant to make tiny adjustments to the car's handling.
@@dreeznation3044 I'm using Metric system (CM), that was the issue. Also, I'm playing FM2 (360) but honestly that shouldn't make a big difference.
@@Vinnay94 Good luck. I hope my video helped you somewhat :)
@@dreeznation3044 I'm trying to tune a C5 Corvette Lingenfelter which has a lot of power but is very slippery.
I really liked the video and the information. I wanted to ask and see if you have taken whats on the video and placed it onto a document for someone to read? I love videos, but at the same time being able to read what you are saying also would be a huge plus.
Here is my Tuning Process in the Forza Forums! forums.forzamotorsport.net/turn10_postsm541098_Viewer-Requested--DreezNation-s-Tuning-Process-in-Writen-Format.aspx#post_541098
excellent
Does rain affect tire temp?
When you say weight ratio. Do you mean power to weight?
weight distribution, when you look at your cars stats its the percentage
Is this Spock from star trek discovery ?
What is the weight ratio?
The formula I showed
Hi there, interesting stuff. Could you use an example of your working out of rear Springs? Numbers that might be involved etc. Maths was never a strong point! lol
So I go into the upgrade menu, and scroll through the car info to find the weight ratio. Lets say it is an Italia 458 and the weight ratio is 44%, so I write that down and save it for later.
While I am test driving the car. I adjust my front springs. Eventually I settle on my front spring force to be 655 lbs.
Now at this time I can use my weight ratio and my front spring value to set my rear spring compression.
I will grab my phone's calculator, type 1-0.44=0.56, then I multiply 0.56*655=366.8, after that I will divide that value 366.8/0.44=833.63. Now I have the rear spring force I will need.
The formula I gave [R=F(1-D)/D] was made from the relationship that [F/D=R/(1-D)] which for us would be [655/0.44=833.63/0.56]
Hope this helps you isolate and understand the math side of this.
If you find all of this just too confusing, don't feel bad. You can get a very close approximation for my tunes using this tuner bg55.com/u2scforzatuner16.php
Set the settings Spring 110%, Roll Bars to 120%, Bump to 130%, and Rebound to 100%
If all you need help on is the springs then just use the spring values from here. They won't be exactly the same, but I have now tested like 20 cars and the values are always pretty damn close!
+DreezNation That clears it up more. Cheers bud!
what is a good base differential setting if you dont use tcs?
Due to huge differences between cars, I can not really give you a base setting. Maybe use TCS and get your tune solid, then turn it off and adjust until you can control your car entering turns and exiting turns
I don't ever do a base differential setting. But usually I will start at 100% acc/ 100% dec. From there I will back off the numbers until things handle well. If things are still strange (can happen in random cars like 458 italia, or GT Porsche) then actually go to 0% acc/ 0% dec and increase value until the car behaves.
What is the weight ratio number and where do I find it??
Tyler Castaldo this number is provided in the statistics of a car inside the upgrades options.
Can i work at formula 1 after i learn all this?? Lmao i think im not gonna touch my settings for a while
Hey, are you sure about the formula for the springs? I got a negative valor.
There is no possible way to get a negative number unless a mistake was made. Here is an example for you to see it working. 51% weight ratio, 500lb front springs ----> 500(1-0.51)/0.51=480.4lbs
or another example, lets make it extreme! 42% weight ratio, 200lbs front springs -----> 200(1-0.42)/0.42=276.2lbs
Hopefully this clears things up for you!
Thanks, you've been crystal clear now! ;-)
Can we just download your tune
Well, I no longer play forza so if you play forza 6 then you can download the tunes I made for cars on that game, but I never owned forza 7 and you wont find any tunes of mine on that game. However, there are plenty of good tuners out there. If you don't want to tune things yourself go ahead and search for them. This video is more for people who want to figure out things themselves.
Good luck man, have fun racing!
Bros I cannot turn in this game it's so aggravating lol
Indicative
Indicative ;)
This part of the game is so fucking stupid. I really just want to drive, not fuck around with all this bullshit. You think Dale Earnhardt Jr tunes his own car? No, he says it's too loose or too tight and the crew fixes it.
Then download a tune another player made.
