Auburn Pro Racer's Diff - F-Body Road Racing and Autocross Forums

I bought this Racer's diff from Sam in October of 2011 and used it for the 2012 autocross season. Then I found a used T2R from the 'good' years and switched to that in 2013. Comparing the 2 diffs (on 315s with 1000/225 springs and factory big 3rd gen sway bars) there wasn't much of a difference except in the tightest of corners where you have to really need to lock the rear tires together. In all other situations I couldn't tell a difference. I had no issues with it the little I drove it on the street, which was always in the dry weather.

Figure about 12 events for the year and just a few street miles since I wound up trailering the car most of the time. It has been sitting around ever since 'just in case' I needed it again. So very little wear on it, maybe someone else can chime in on the exchange program. I didn't use the friction modifier that came with it, and it is included. Also included are carrier bearings with one race marked as the ring gear side.

Asking $400 plus shipping from North Jersey, paypal preferred. Please include your zip code for a shipping price.

Which, if you use the military convention for months M is December. If you use the standard alphabet M is the 13th letter and obviously there is no 13th month! (The military skips I since when stamped it could look like a 1 or lower case L). So you can get this season out of it then send it off for a new one... so price is now best offer! http://aftermarket.auburngear.com/d_rex_program/ (IMG:https://lh3.googleusercontent.com/-L0zcX1DoNq0/VRdDSzjTQGI/AAAAAAAAEzc/MJ5Hu9V3Jvs/w413-h551-no/20150327_140139.jpg) This post has been edited by slowTA: Mar 29 2015, 12:18 AM
