How much do heavy wheels slow you down? Testing the Audi RS5

- How much does more rotating mass affect acceleration? I take the Audi RS5 out for some tests to see if my heavy aftermarket Vossen HF-5 wheels have added weight and slowed down my 1/4 mile time. Testing is done with 3 runs on each set of wheels using a Dragy. The Audi is completely stock at this point other than the wheels and tires. The lightweight wheels are factory 20" Audi Peak wheels.

If this tested handling you might see a big difference depending on how the suspension is tuned. Adding heavier wheels makes the suspension less responsive. Thanks for taking the time and effort to show us what a difference the weight of a wheel and tire can make to acceleration. Great looking car btw
Thanks!
So it don´t matter in real life - but the aftermarket wheels look much much better !!!
@rolexr I agree! They look so much better. They will be going back on after Street car takeover!
The rules of physics say there’s definitely an improvement. Is it worth the money is the question.
I agree. Some light weight wheels can be ridiculously expensive!
Great vid. Would be interesting if there's a difference in handling at highspeed between those wheels. Could recognize some difference with my 435i at fullspeed (german Autobahn) between old and new tire (Pirelli). Steering wheel vibrate much more with old tires, idk. Original wheels looks better to me for RS5 tbh :)
Thanks! I can tell you the Nankang tires have way more grip than the Hankook tires. It would be interesting to test both wheels with the same tires but I feel like the wheel width would also be a factor in that test. Stretching the same size tire I can fit on a 9 inch wide wheel vs a 10.5 inch wide wheel could be difficult.
just so you know a reason race cars n other performance based setups run smaller rims is to save weight. Alot of cars that can run 17s or 18s on the street will run 15s or 16s on track and roll racing, going down 2 inches will save you prob another 10lbs and give you better times aswell as beefier tyres for more grip aswell as more fuel economy and better handling. great vid
edit; no matter your tune get better grip tyres and ones that have more rubber on them these rubber bands rly would hamper your tune. im not saying go drag pack but some 16s with OZ racing wheels ,rpf1 wheels or idk other lightweight options you like. it would prob make that car real close to a 10sec car maybe even so on a drag strip. bcs idk if youre spinning rn or abs kicks in with those rubber bands but i would think it does even with quattro.
Maybe look up what the golf gti and r guys run on their roll race cars, like Jewels gti and SportyMk7.
All good points! I would like to have a drag setup like that ....but that might come later if I keep pushing the car further. To your point, more sidewall and even less weight would be great!
the only reason to put bigger rims is to put bigger brakes inside
I have the same wheels on my nardo grey but i have the super deep comcave. Best wheels for this car. Also I have a stage 1 93 from IE
I just installed a tune from 034 motorsport that will be in my next video. How do you like the IE tune? Have you done any 1/4 mile runs with it yet?
@@AutomotiveAdventureJunkie I think its pretty good. I had a stage 2 tcu also but it was way too rough for just cruising around so I went back to stage 1 tcu. There's probably not much difference between the two companies but I think I saw some videos finding that IE had better times slightly. I haven't done any 0-60 or 1/4 testing
I've heard that too about IE. I think their tunes are a bit more aggressive.
Great comparison vid! Are you going to run e85 once you install the tune?
No, I don't have E85 at the pump where I am and this is my daily driver so I'm sticking to 93 octane.
so different sized wheels and different size and type of tire.... that's not how you do a comparison. 🤔 mass closer to the center does not need as much energy to move as something with more mass towards the outside. So even a tire that is 2lbs less will have a positive affect as there is less mass on the outside. however, adding larger brake rotors can have a negative result because those are heavy steel disks even though they are closer to the center.
Yep, in ideal conditions it would be great to have the exact same tire and wheel size for the comparison. It's just not in my budget to go buy another setup just for testing purposes. Maybe one day....
Original wheels looks so much better to me. I dont get this "everything black" fashion.
@mikulasberka7999 Touche! The stock wheels are very nice as well. It all comes down to personal preference.
silver wheels are boring AF
Black wheels are a current trend and silly..like Bell Bottoms were in 70's. It'll go away some day lol
That’s a bit ironic to say considering most cars come with generic and overused silver wheels or “diamond cut”. The car is gray with red accents so you’re just exaggerating for the sake of complaining
@@c0348whn Nothing ironic about that. There are things I like and things I dont like and I dont like black wheels or windows on dark cars.
