michelin pilot sport cup are competition slicks that can be used for the road, my rims are currently just shy of a 12 inch on the back, the 305's stretched somewhat so a 325 will just do me nicely, my spacers 35mm are coming in this week, due to the rim offsets and wide body at the back "only on the back, front end, well I gave it a miss" the 305's look like biscuit wheels...

 

I got 560whp and using Michelin Pilot Sport 2, they hook up very good, the only down side is they are dam exspensive. My rear tires were over $600/each.

 

Got michelins 325/30/19 s semi slicks and they r great but first gear is not hookin and second sometimes but overall cant b compared 2 any thing

 

If your looking for a 345 tire get the PS2's that are for the Vipers. Do NOT get the runflats. These things handle the instant torque about as well as possible.
