Opinions wanted on Wheel adaptors, are they safe?
 

I'm looking for opinions on wheel adaptors (not spacers). If they are safe / don't cause any vibrations or issues with changing the load on the suspension etc.

Example:
http://www.skulte.com/product_info.php/products_id/58

This would be 90% a street car (with occasional track use). The suspension / brakes are completely redone: GW uppers/lowers/coilovers/c5 brakes with AFX spindles, g-bar/mini-tub/12" discs in the rear and because of that I don't want to have to worry about breaking something either when I drive it hard (which I know I will do).

The reason I would need to run wheel adaptors in the first place is, I want to run the Wheel Vintiques Billet Rallyes (series 90) on my front C5 brakes from Touring classics. I know they won't clear. I haven't measured yet but I probably need a 3/4" to 1" adaptor to clear the caliper / brackets.

This would be the look I am going for (not my car 'shopped):

I am kind of going for that sleeper look and really just want to run the rallyes, I have looked at so many wheels that will fit the C5 brakes, but I still just want/love those rallyes :yes:

Thanks in advance :thumbsup:

I met a guy a few weeks ago who runs his 81 Camaro in the Cannonball One Lap of America. He has Z06 replica wheels on it with at least 1" spacer / adapters. They bolt onto the hub with regular lug nuts and have a separate set of studs for the wheels to bolt onto.

He runs his car hard and has been running them for the last few years without a problem.

A properly designed and machined wheel adapter is safe. I've heard good things about Skulte Perf, but have no personal experience with them. A lot of people have had good experience's with Motorsport Tech...I however am not one of them. There are a lot of hacks making wheel adapters, so buyer beware.

Something commonly omitted on custom wheel adapters are torque rings on the surface that mates with the rotor. Torque rings are designed into wheels so that they stay tight and maintain a consistent lug nut torque. They can be either concentric rings or pockets that align with the wheel stud holes that actually allow the lug nut to preload the wheel center and equalize the contact pressure between the mating surface of the wheel and the hub/rotor. Without this feature, you get very high contact pressure (and therefore stress) near the wheel studs and progressively less the further away from it you get.

We run them on most of the cars we buid so the guys can still run the huge drag slicks on the cars. Just make sure you buy a good pair not a cheap nockoff. I have used all the way up to a 2-inch with no problems or vibrations. This car runs a 2-inch with 19X12.5 rear wheels and no problems for over 2 years now

Thanks for all the good information.

So for a good set of wheel adaptors it sounds like a set from Skult or Motorsports tech is the way to go? Unless someone knows of any other good ones to check out?!?

Thanks again :bow:

As I said above, I'd avoid Motorsport Tech, but that's just me. Another manufacturer that makes very high quality wheel adapters is H&R. They make what they call their Trak+ spacers and adapters in various thicknesses...the only issue with theirs is that they are what they are, no customs, so you're stuck with the thicknesses they have to offer. Aside from that though, they're TUV compliant and very well made.

Where do you get the H&R?

Ah I misread you, just read the first part not the second how you didn't have a good experience with them.

Are these the H&R adaptors you are talking about?

Thanks again!

Those are indeed the adapters that I was talking about. I got the last set from one of their distributors in WA state, but I would suggest going through the distributors listed on their website until you find one with the best overall price and/or has the item you're looking for in stock.
