[QUOTE="biminiLX, post: 15683588, member: 7795"] Love that color in the sun! I'd love it if someone would offer a 27" front DOT radial skinny, I just ordered 28" M&H bias fronts. Anyway, the stock gear and clutch thing is completely based on mechanical advantage. 4000# car with 2.66 first gear and a 3.31 rear gear puts excessive stress on the clutch compared to 4.10s. Simply not enough mechanical advantage for drag launches. NJTony and all the fast 3.31 cars hurt the stock clutch, even aftermarket clutches have failed. The clutch was the fuse. My 4.10s went in around 1000 miles and after drag use and about ten 10 second passes looked almost new. My tuner said it had to be the gears also as his 3.31 car only had a handful of track passes and looked worse. So, just a friendly warning but it's when not if the stock clutch goes if you continue to drag with 3.31s. Same goes for gear whine, eventually drag use (with any gear ratio) will cause whine. In HindNOS case, the bias ply tire is helping but I can almost bet if puts on street or stock radials there will be whine on the highway. -J [/QUOTE]
