One more time,

OK, I just want to leave two big black stripes when I drop the clutch. I've got the standard (I think) 3.10 open with a Tremec 3550 (.68 in 5th). Should I be looking at a 3.73 or the 3.46? I have a 351W with about 400hp at the crank (not sure of rwhp).

My concern is running out of first gear too fast at it is a 3.27 ratio. Wouldn't the 3.46 allow me to shift later out of first?

Also, where is the best place to get a limited slip unit for a Backdraft. Bimmerworld has been mentioned. Any others?

SkipB
