You have some seriously lousy tires

You have a significant problem, and it's not your gears.

I'm putting out 510hp on the chassis dyno, and I don't have a serious traction problem (unless I want one). I use a 285 rear tire.

That may not be the best street traction tire on the market, but it is pretty darned good. I use the same tire in a 285 width, and I don't have a traction problem. I can spin the tires when I want to, but it only happens when I want it to. If you have a "sever traction problem", there is something wrong somewhere. Your car will be a lot more fun to drive when you figure that out.

There's no such thing as too much power, only not enough control.

I would have to agree, im doing about 450 at the wheels with 275's and dont have issues to that point, even with eagle gt's.
