Default dunlop star spec tire pressure ?

Just ordered a set of 225/45-17 star specs, autox coming up on Sunday. What would you guys recommend I set the tire pressures to?

08 wrx, epic egr springs, ~1.3 neg camber, its going to be in the 50s

Before I was in stock class on re92s and bumped up the pressures to f40/r38, but for some reason I don't think ill need to go that high on these. I want more oversteer so rear pressure higher than front?

I had decent luck with running my star specs- exact size as yours too- around 36-38 in the front and about 44 in the rear to help with rotation. My car had terrible understeer and the higher rear psi made a difference for the better. I've done some other things to help the understeer so I may not run that high in the rear this season. I'll know more after the first event in 2 weeks.

I would agree try 36-38 in front and in back try high pressure but if that doesn't work try dropping it way down to like 30 if needed repressiveness will be lost so it might not be the best idea.
