flat wheel spacers
Hey all, got a quick question. I have a 1990 with the speedline c5 wheels. There is a small gap that I want to fill 1/2. I want to get some wheel spacers. The only kind I can find are the flat style. The company that's selling them state there hubcentic on GM 70.5 hubs. I want these for front and rear. I'm scared of vibration, any one have any experience with these? Thanks

About the "thinnest" pass-through spacer that can be done and maintain a hub-centric fit to the hub and also the new wheel is 16mm. Using the 16mm and dependent upon the fabrication there should be no issues BUT you'll need longer wheel studs. The one most use is a GM part #'d product that's sold by dealers, Summit, Jegs and many others. You'd have likely $140 in studs + the price of the pass-though spacer. The install isn't a problem.

I've ran 1/16-1/4 on fronts np and herd 1/2 was max for rear drag. If your not running a super sticky drag tire or doing some hard cornering I'd run em. Make sure you re-torq as aluminum will compress some(bugs me I can never rem the technical term).
Min adapter is .8 and then you'll still have studs sticking thru that you have to cut or get wheels that clear them with pockets or multi-lug pattern.
