36 psi front 34 rear cold tyres dunlp sport s200 195/60r15 , the back end WILL come out on hard quick cornering or a minor tweak of the hand brake. in the wet though it doesnt handle well due to the sway bars ,it has a little bit of body roll WHERES YOUR LOCATION WE SHOULD HOOK UP SO U CAN CHECK MY SUSPENSION OUT . the responce is great as well as the feed back ucan tell when the rear tyre traction is about to give so u dont push it any harder and loose controll. exactly what did u get fitted to your car .just remember whiteline goes for a complete package most car owners use a super hard spring to over come body roll which is really not a good idea for road use , oh ther ride its harsh my friend told me but it handles well so i dont care but its really up to the driver weather he/she considers my ride harsh compared to others
