Upping the boost on my supercharged si; and even with pilot sport 4s tires, I still spin 2nd (will be installing gear x gears here shortly - which should help with traction because of the longer gearing). I'm looking for some tires that will give me more grip. I've done alot of research, but it seems like there are mixed reviews on every tire. My predicted new power level will be in 450whp range. I was looking at r888r, a052, and other streetable track tires. I'm planning on just installing them on the fronts. Does anyone on here have first experience with r compound tires in terms of grip and daily usage. My car is mostly driven on nice weathered days and is not my daily car. Thanks.
