Heres the deal, I want to go to a 17 x 8 wheel probably running a 235/50-17 which are 26.3 tall all around on my 1971 Duster. This size tire allows me to run modern maximum performance summer tires while still retaining enough sidewall height to look correct. Ideally I would like to run the same size wheel with the same offset (BackSpace) all around as well. I may consider larger rear tires for the track if traction is a big problem.
Since Im also upgrading the front suspension to 73-76 spindles with 11 ¾ discs with Gen I Viper calipers that will push the front wheels out requiring a wheel with a lot of positive BackSpace; it seems that the narrow A-Body 8 ¾ rear is not wide enough and will require a much deeper negative BackSpace to push the wheels back out into the quarter Panels. If thats the case, I cant rotate the tires front to rear and would have to carry a generic spare tire like a 205/70-15 on a steel wheel assuming that would clear my front brakes.
Question:
Would a 8 ¾ B-Body rear that is 3 wider overall push the rear wheels back out into the quarter panel enough so I can safely run the same positive BackSpace wheels front and rear? What BackSpace am I looking for (5.5 Im guessing)?
Help!
