Hey all, new here. I'm looking for any and all helpful suggestions. Over the weekend, I broke my pinion on my borg warner in my 89 firebird LT1 running CMC2. I had been running a 3.45 gear but was considering going to a 10 bolt and a 3.90.
Any suggestions regarding the rear end and differential is appreciated. |

QUOTE (wastntim @ Sep 13 2010, 09:18 PM)  considering going to a 10 bolt and a 3.90. I have been running that combo for two years, with an Auburn Racers Diff. I use a late 4th gen rear, with LS1 4th gen rear brakes, which are adequate. I have only found 3.90s from Motive Gear (made in Italy). All is fine so far! |
