wheel spacers

[Charley7]

Is it safe to run wheel spacers for road race and or autocross. The bolt on style. And how thick is the limit one would go. Thanks.

I cannot say how thick they should be, I think that would be determined by stud length/strength? I will say if I ever had to run them I would make sure they are hub centric on both sides.

Ideally the proper wheel and offset would be best without any spacers, but they can be used if the budget does not allow as long as inspection and wear/breakage is inspected religiously. Also check with any HPDE rules that may rule them not usable.

Most hub adapters with additional bolts/studs are 1 inch minimum and can go up to 2 inches. I would recommend nothing more than 1 1/2 inch. I have used them, just be sure to check torque on all studs to ensure nothing is loosening up. Anything shorter than 1 inch I would recommend a spacer and longer wheel studs.

Thanks for the input guys. My car requires a custom BS so trying to keep cost down for a second set of rims and tires

I have used wheel adapters up to 3 inch in heavy duty off road conditions. wheel spacers and wheel adapters are different in that the adapters have studs. Good quality adapters are pretty much bullet proof, but, they do stress the flanges of your axles. Axle stress increases proportionally to the size of the wheel adapter. If using wheel spacers, Limit is usually considered to be 1/2 inch, as this placed additional stress on the studs themselves. Wheel spacers may also require longer studs to be pressed into flanges to ensure adequate stud extension beyond the lug nuts when wheel is installed.

Thank you didn't know they were different names for the design.

I'm sure there are others, but here is the company i fund when I thought I needed rear spacers.
