1968 Camaro rearend width

[32deucecoupe]

I am looking to have a 12-bolt rearend built with new axle tubes, ridetech brackets, disc brakes, etc..at this point I need to decide the overall width flange to flange. The car will be a driver with some roadcourse at the local goodguys shows and other misc events. possibly more in the future if I get hooked.

I just dont have the knowledge to know if should stay with the stock width, go wider, or narrower..what is best for the stresses on the bearings and axles it will see on the track. obviously too narrow or too wide would not work..do you center it in the wheel well??

In the process of replacing the floors, then add the DSE minitubs for the 335's. 4-speed car, 400hp SB

thanks, Jeff

I would pick out your wheels first. Then you can mock them up in the wheelwells, positioning them for good clearance & desired ride height. Measure between the mounting surfaces & you will have a good rear end width measurement. Be sure to allow for the width of the rotors in the equation. Scott

What Scott said above or - since you are mini-tubbing and going with 335's, give DSE a call and they can tell you what rear end width and what backspacing they use/recommend. From there you can alter it some if you want. A stock 1st gen is 60" outside axle fange to axle flange.

I agree, pick your wheels FIRST! Then mock them up under the car and measure the WMS to WMS distance. This will be the final width you want. If you are not sure what WMS is read this thread.

Vendors can give you approximate numbers, but the ONLY way to get the exact fit you want under your car is to buy the wheels you want first. Then mock your wheels up and measure the exact WMS to WMS dimension based on your setup.

thanks for the great advice...now if i can only get this floor installed we can move on to the next step.

great looking cars by the way.
