Ar-1 pressure

[Philip Griffiths]

High. Just wondering what cold pressures people are running in their 1*2.

The cars totally stripped out, full cage etc just as a gauge of weight.

Thanks

Do a 1-2 warm up laps, then 2-3 fast laps, come in and check pressures. You want about 28-30psi hot.

My MRF’s are about 23/24 cold and ideally 28/29 hot. Slightly higher on the rear but that’s my personal preference.

I ran them in Combe last weeks and got they were 25-26psi but found they were starting to wear the centres.

Was that cold or hot?

I usually start at 25psi and then bleed them off a few times until they stay consistently at 28psi hot.

I've found my ar1s to wear the centers on the front too. Even trying lower pressures

I even went down to 19-psi cold to see if that would help
