Track Tire Pressure

[Sotally Tober]

Do any of you adjust the tire pressure for drag racicing off the line?

How about roll racing?

What pressures is everyone running on for daily driving?

Factory works well. Lower could cause more drag and slow you down. Suspension on full stiff to help keep weight on the front tires. Go get’em !

Thanks! Vids will be posted tomorrow. Track Hawk will be a no show due to a recall.

There was a guy in a trackhawk right next to me yesterday at a stop light. We were surrounded by traffic but anyway I could tell he was "curious" lol. My biz partner was right behind me in his new RS7 as well. How I wish we were on some deserted empty road somewhere haha. RS7 already knows what's up (not tuned).

Ohh what a missed opportunity 😜. That RS7 doesn’t mess around either!

So I was doing some digging in the manual and found this:
- Recommended tire pressure under 100mph - 36psi Front and 36psi Rear
- Recommended tire pressure over 100mph - 43psi Front and 44psi Rear

That said, should I stick with the under 100mph set up for my roll race tonight or bump it up to the over 100mph?

When you say "roll race", are you starting from a static mph ? Like both vehicles at 50mph, then go ? If yes, I would bump the air pressure up.

TELL me about it. The RS7 ate X5M dust on many occasions already lol. We have played around from a dead stop, 2nd gear roll, and more.. X5M pulled on the 2nd gear roll BAD. Everything else I was about a half car in front. I keep telling him to get the damn thing tuned. If he does that it will eat me up for sure. I think those RS7's jump like 150hp and 170ft of torque with the APR tune.
