We run a GM metric with a 9" Ford rearend it is 63" long and it gives us quite a few options on wheel offsets but I am thinking of cutting it down to the metric size. Any thoughts on this subject will be appreciated.

There was talk about this same topic a while back with varying opinions between 60 and 58 inches. I would probably go with either of these sizes. Our current rearend is a 58" but Wayne Larson stock cars normally use a 60" rearend.

I ran a stock metric 10 bolt in my car (RULES) and I borke an axle and bent the rear end. I had just got a Chevelle super stock and got some stock rear ends with it. The spring cups had to moved close to the front of the housing and it was a lot wider then the front. A lot of guys said that this wouldn,t work very well but afer that the car came to life. I could run harder into the coners more then anybody else. I put 2 offs on the front and switch rear from 3 off to 4 off for heat to main. The rear was still about 2 inches wider than the front. I was surprised and never told any body my little secret. SSSSHHHHHHHH!!!

I have been running a 62 inch under my metric for three years now and like it. 4 inch offsets on the rear 8 inch rims and 255/70/15s with the sidewalls flush with the quarters. Works good for me.
