Posted this in the C5 Tech section too.

I have an 02 Coupe with A&A V3 S/C, 3.42 gear, 2600 stall T/C, shift kit, Thunder Racing blower cam, 60# injectors, Lingenfelter high capacity fuel pump, handful of other mods. Dyno Tuned at XXX Motorsports in P'cola. I put down 470rwhp on a Dynojet. I'm consistently running 7.40's in 1/8th mile (best is 7.35).

I've just worn out BFG 295/35R18 on aftermarket 18x10.5 C5 Z06 replicas. They definitely are way better than my stock street Kumho's, but I still spin almost every pass. I'm about to get headers, but then I'll be putting down even more rwhp to the wheels and will likely spin even more. The blocky tread pattern is history - totally bald. Why don't these hook up like a slick now?

I've been looking at the Mickey Thompson website, but I'm confused. Everyone says to go with slicks instead of ET streets. But nearly all the M/T slicks are for 15" or 16" wheels. They do make 305/35R18 street radials that will fit my wheels, but they're not slicks. They also sell wheels which their slicks would fit, but I can't tell if their 15" wheels would clear my stock brakes/rotors (in fact, that's why they claim they started making the 17" and 18" tires for sport compacts, Mustangs, Corvettes, and Vipers).

Are any of you guys running slicks on your C5 with stock wheel hubs/brakes/rotors? What's the magic combination?

 

Not an expert but here's some good things to know. I run the CCW drag pack with 16" wheels and 26" ET Streets and skinny Firestone bias fronts. After trying a couple drag radials, these are my favorite combo so far for track use. To make the 16" wheel fit the rear, it requires a little hammer work to flatten the top ball joint, that's it. You can get a set of ET Street in 17" that will fit on Z06 front rims, with no mods required. If you run like that on radial front it's too squirrely, so you're wise to use bias fronts to match the setup if you go that way.
