How much power do you have? I've got the stock 275's and they're useless with the 2.80 blower pulley. Car won't hook at all. I punch it at 55mph on the highway and it will break them free. I've never run it with DR's though, so I can't say how much difference it would make.I know!!! I have found 17's all over but I just need a BIT more style under my car for what I'm planning. You think I'll really loose much with a 285 or a 295 over a 315 rear?
I guess my question would then be, do you really need 18's? I mean, a 17" wheel isn't noticably that much smaller, it will give you the width you want in a 10.5, and it allows for a little bit more sidewall (which should help you hook even better). I mean, is there any reason you absolutely need the 18" over the 17"....if there isn't any out there it is probably for a reason.350rwhp on a Mustang dyno, so a little over 400 on a dyno jet N/A. I have a 50-150 wet shot. 18's with DR's will be my street setup, so I will do a lot of roll races with it, and my dig's are usually off of quite a bit of slip. My 8.8 rear is built and I have yet to have a problem hooking with my slicks at the track.
