Yea - one of my pet hates is people on the forums not using the search function before they post a question, and then i go and do it myself! D'oh!

Most of the replies seems to say 2 or 3 psi more at the front, so i think i'll go for 34 front 31 rear for now & see how it goes.

Cheers though.

No dont think so.Maybe heavier at front due to engine .only guessing though .(not guessing its heavier ,just assuming its the extra weight needing slight higher pressure.)Always been higher at front in both my Scoobs.

More weight up front plus a bit more pressure at the rear can help a little to combat understeer tendancies.

Try 32Front, 32Rear and see how it goes. Lower profiles should run a bit more pressure. If the car feels a little too light at the front end then try dropping the pressures by 1psi. Kinda a case of trial and error until you find a comfortable setting.
