Correct Wheel Backspacing for 5th Gen??

[cudacoupe]

I am trying to figure out what the back spacing should be on my 84 Elky. I currently have Camaro z28 rims but they need spacers so they do not rub on the upper control arm. I want to order new rims but I do not want them to rub like my Z28 rims did before I installed spacers.

Thanks,
Billy

You are best off going with no more than 4" of back spacing. Anything more than that would have interference issues and you would need to use wheel spacers.

I'm running 4.5" bs with no problems on a 17 x 8" wheel. Car Craft or some other mag did an article a while back on a Malibu they were doing. Using some fancy gizmo they determined that a 4.5 bs was the best.

Anything from 4 ~ 4.5 should work fine unless you're going to try and fit a really wide wheel.

Am considering new style Cragars 15X8, plus lower by 2". 84 G-body. Share your wisdom ole pros!

I use a 17X9.5 5.00 of backspace..Never any probs There are allot of elky owners that are finding this out these days.Good luck and post some shots! *Note that iam running 17" rims with 40 series tries* Bigger series of tires could and would be a prob.5.00 of backspace is the max on any 5th gen that i have ever seen with-out raising the car to accomadate the width.I use a 2" rear drop spring (hotchkis) and global west aluminum shocks.The currie rear does not make a difference in size of rims or tires on my elky.
