Has anyone used a 1/4" flat spacer on the rear wheels with out problems? I just got my new ZO6 wheels(18x9.5 56mm offset) and I want to bring them out just a little more in the back. The problem I see is that when I put a regular flat spacer in place the hub no longer touches the wheel and I wasn't sure if that would be a problem. Is the hub centric feature important to the mounting of the wheel or do the studs handle all the load anyway? If this is not safe, I was looking in to the Doug Rippie 3/8" hub centric spacers as the other option. Thanks for the help!

 

i got some 1/4" spacers from a guy recommended off this board by BruekSteve

the guy's name was Fred Groeske i think, but you gotta send him check or money orders cuz homey don't do credit cards.

 

The 4th Gen wheels are "centered" by the conical lugs. They do not require the center of the wheel to be in contact with the hub.

The problem with spacers is that they change the loading on the studs from (almost) pure shear to shear plus bending. That means the stess the studs need to resist is increased. I use 5/16" spacers on the front for my Weld 15x3.5's, but I would hesitate to use them on the rear wheels, particularly when running slicks. If you are just looking at "spirited street driving", 1/4" spacers should be OK.

The "adapters" that bolt to the stock studs, and then include a set of new studs for the wheels to bolt to eliminate the issue of the studs taking the bending loads. The adapter is designed to take the loads.

 

Thanks Injuneer. Yeah I do a little "spirited street driving" but not much and I never use slicks.
