PSI for A7's Auto Cross

[ncgoblin]

I just mounted my A7s 235 front and 275 rear. I am wondering what everyone is running for PSI cold and hot for Auto Cross.

Thanks

I've been playing around and so far min like 20psi up front and 22 in the rear. There's alot of things that effect their psi but start there and play with it. Use chalk to mark the edges if your tires so see if the changes help or hurt.

I think the higher pressure was a lot better 14/16psi was too low IMO.

In reading posts from Ariel Atom owners, one posted 19-20 psi hot was working well for him. This was road racing.
Might also grab a HF infrared heat gun to measure tire temps across the tread surface to see if they're running even.
