hub-centric spacers- bad idea?

[diesel25lrs]

I'm possibly looking at 1/4" hub-centric spacer on my front wheels... Anyone out there doing autocross/road racing with them? I'm not sure about using them due to the weight being tossed back & forth on them... 650rwhp- no spacers on the rears.

Thanks for the help!

A good quality hub centric spacer is not a problem. Wheel spacers are commonly used in all forms of racing at all levels from amateur to professional. Just make sure you buy a quality spacer that fits your hub correctly and not the generic ones.

What should it be made of? Someone had suggested cryogenic treated steel? Does it matter?

I used billit spacers on a set of 17" corvette wheels for almost 2 years of SCCA, AutoX, and goodguys events without even a lug nut even coming loose, the newer spacers are not cast junk like they were in the 60s-70s and 80s, the old stuff used to crack

What kind of thickness are you talking about Rod? If you happen to remember?

This car will also see a lot of miles- DD...

Hey Josh, they should be able to cut billet aluminum spacers. The same material they use to make the centers would be your best bet. They MUST be double hub centric. Meaning the spacer centric on the hub and the wheel centric on the spacer. Also make sure you have enough length on the wheel studs. Some people overlook that and end up breaking studs.

This. When I had my spacers/adapters made, the company wouldn't even make them unless I gave them the measurements for the spindle/axle hubs AND the wheel hub bore. As long as it's a quality material and it's made for both the inner/outer hub dimensions for your car, spacers are no problem.

I used 2 inch spacers on the front and 2.250 spacers on the rear, on a set of corvette wheels, here you see me testing the suspension just before I painted the car

I wouldn't think twice about running a 1/4" spacer..... The link posted above can machine spacers to center on your hub and your wheel. As stated, make sure you studs are long enough and strong enough.

What is a good rule of thumb to determine if the studs are long enough?

I have 1.5" from the mounting surface and want to run a 12mm spacer so is 1 1/8" enough stud?

[TheJDMan]

The rule of thumb is that you want studs long enough to see a couple of threads exposed on the outside of the lug nut when tight. That said, I'm running 3" long studs front and rear with 6mm spacers on the front.

anything over 1/2" thick and i would only use bolt on spacers. ones that have new studs coming out of spacer itself.

Than that is an adapter... adapters have studs mounted in them, spacers dont.
