Tire Pressures????

I STFA and found that people with 18's usually bump up what the gas cap says by 2psi..... My question is do people use the 33 and 30 as a starting point, or the 36 and 33 as the starting point? I think that the 36 and 33 is for a car with a full load, but i can never be too sure......
TIA

No Sways?.......>

In that case it really depends on how you have the Koni's set up front to rear. I'd start with 36/34 and adjust depending on oversteer/understeer...

On my old set-up 36/36 was pefect, but I had a rear bar, MK1 arms, Haldex controller and didn't need to compensate for understeer with lower rear pressures.....

OK...In that case Josh...>>

I'd start with equalized pressures front and rear 36/36 and fine tune using the oversteer/understeer chart in the FAQ..
