The rears are 18x9.5 tires: 275/45, and fronts are 18x8.5 tires: 245/45. As for feeling faster, yes. A LOT faster, ha ha. With the 33's it took me a while to get up to the 96mph limiter but now it hits the limiter and has enough acceleration to go up to about 105 before it starts to slow itself down to 96. And after replacing the freakin waterpump AGAIN, I'm taking the mechanical fan off and going e-fan. Then an SCT programmer
. I'll have to get some better pictures once i get my camera back. Right now in the front it sits about 3" lower than an XL and about 1.5" higher in the rear (for right now).
