rim backspacing with mustang II suspension
Hi,
I need some info regarding the rim backspacing for the front suspension on my B&B. I know there were posts before but they didn't specify if it was stock suspension. B & B gave me the wrong tire size and possibly the wrong backspacing, that's why I am having so much trouble with tires rubbing. I currently have weld rims with 3-1/2 in backspacing with 255-60-15 tires. After speaking with B&B again they said the biggest tires they suggest for the front are 235's with 4-1/2in backspacing. Darryl was not sure if the 4-1/2 in backspacing would work with stock suspension so I have to wait until Bryan gets back from vacation next week. Does anyone run 4-1/2 in backspacing with 235 tires on stock suspension??? This is one costly mistake already I don't want to make another one. Thanks Jim Tested the locking rear last night... that works! |
I'll go get a tape measure and be right back.

As best can tell without taking off the tire, It has 3 1/2 inch backspacing. This is on stock a arms.I'm running 235's on the front. If you go with aftermarket arms you can use 4 1/2 inch backspacing. I tryed my locking rear end out when in the build stage too. Worked the length of my driveway!!!!! jim

Thanks,
I guess I will stay with the same rims and get smaller tires. As long as the 235's don't rub when mounted on rims with 3-1/2 backspacing. Jim |
I have measured wheel wells to find out how big a tire I could fit with a homemade "T-square" constructed from two pieces of 1" angle iron. One bolts to two wheel studs and is your radius, the other T's off the first piece to establish width. Have the suspension compressed and wheel off, by rotating the angle iron, you can determine the working space available for tire and rim.

I'm running 235/60-15's on Team 3 wheels with 4 3/8 backspacing. Tires are even with the outer edge of the fender and they don't rub anywhere. Stock MustangII suspension with 11" rotors and GM calipers.
