Re: Drag Radial ET drop (black_89_vette)
It's anywhere from 1.5-2 tenths for every tenth.
As long as your clutch is good, you should see an improvement. Inmy case, I think my clutch was on it's way out, my 60' on street tires was just as good as with drag radials.
If you aren't spinning on street tires, you may not see an improvement at all.
But if you were spinning off the line, this should help quite a bit.
Best way to find out is to get outthere and do it.
