Does anybody know the exact backspacing associated with the Group IV Campi 10 and 13 inch rims. I making up a set of rims and am wondering what the factory used for back spacing.

Hi,I dont know about factory wheels, but my backspacing is 4.5 front,4.0 Rear on aftermarket wheels with fiberglass GT5 flares. They fit well,no scraping.
Lee....perhaps this may be helpful. I have a 74 with the GT5 body kit. It is running Gotti wheels 15X10 and 15X11" with 265/50s and 305/50s. From the inside bead to the wheel mount is 4.5 for the fronts and 3.75" for the rears. The tires are BFG euros TAs. Perhaps you can tell me about your plans to build your own wheels. As I am looking to upgrade to 17" wheels in the near future and while I am more than happy to support our vendors....the vendor prices of 2900 to 3200 bucks for wheels ALONE has provoked me into looking elsewhere. As it turns out, the local Dr. of speed does some work race prepping the local Viper drivers and suggests going to a guy in Florida at www.ccwheel.com This guy will build what ever you want for a price of 1700 to $1900 for all four wheels. Here is link to a pic of his work http://viper.epikos.com/Uploaded/23103755pm1079.jpg Let me know your thoughts. If you are making one set, maybe 2 sets would be better............Doug.H
