i have a question for everyone i know that this has been dont to death so forgive me but i need the backspacing for my car so i can buy rims i have 86 iroc 16 x 8 's on it now i also have 4 wheel disk brakes if that helps :hail:

 

The easiest and surest way to make sure you get it right is to just take one off and measure it. After all, you're probably spending a lot of money on new rims. Take the wheel off and lay it flat, face down on the ground. Lay a piece of metal, wood, whatever straigt across the back of the rim (the outermost edge, where the weights are attached). Then simply take a tape measure or ruler and measure straight down from that cross piece to the inside mounting surface of the wheel (the surface the lug bolts go through). That's your backspacing. Any reputable tire and wheel shop should be able to do this for you, and to check clearances with steering linkage and the like (which is especially important if you are changing wheel diameters). It's also a good way of finding out the attitude of your wheel technician people. You don't want to give two or three grand worth of tire and wheel business to someone who is not going to really take the time to get it RIGHT!

 

ill have to do that yeah im looking to spend at least a grand on rims but finding ones that i liked for a RWD car is next to impossible locally anyway most places have junk for us (in stock) and they have everything for the average ***** but anyway thanx
