Buying 9"
Buying 9" I am about to purchase a 9" street package from billingsley. I am going to do 35 spline axles, light weight spool, & pro series case. My car is an 01 z M6 running 224 cam, exhaust, & shot of dry nitrous. I am running 255 50 16 BFG
DR's. I have the weight down to 3150 pounds w/o driver. What gear ratio should I go with? I am thinking 3:89 I am running on the stock tune so I think the rev limit is 6200. I have my shift light set at 5800.
Any experiences with 3:89 & the m6? Or would the 4:10's be better for me? I am looking for the max for the track (1/4 MI)

You'll benefit from either... don't see much of a difference between the two, seeing as the cam isn't that big... but then again wtf do I know. What kind of track numbers are you getting out of that car anyways?
I've got a rear very similar to what you need for sale.
