Wheel Half Tire Retension Hump

[rjwoods77]

I am considering making my wheel center and outer half the same because of the offset,single nut retension setup, etc. I can make it easy enough but I am curious about the inner wheel profile. I found the metric specs on internal rim design and am trying to figure out which would be best for a fsae. They have retentions from none to super strong depending on application. I know some of you run those bbs rims which are supposed to be the best out there fsae and wondering if it had a rating cast in the side to identify what it is. Any thoughts on bead retention humps anybody?

13" BBS wheel half and center drawings have been sent to FSAECAD@gmail.com

Forgive my ignorance but what is the fsaecad@gmail.com. This is the first I have heard of it. Is this like a google groups kind of thing?

Anybody car to share the drawings for the Centerlock version?

We've tried contacting BBS USA with no response in email or by phone. I even contacted the German FSAE rep, but he just forwarded me to his US counterpart who did send me an email then proceeded to drop off the face of the planet.

To vouch for BBS Motorpsport, they don't have alot of guys there and they take orders all the time. The fact of that matter is that theyre going to take care of the customer buying 40 wheels for grand am ahead of us. Its difficult but we have to be patient. Drawings sent to fsaecad.

Yea. I guess I kind of figured that, but I also thought they must get these questions often enough to have a generic packet they can send out, or hand me off to a sales rep who can give me basic info without tying up more valuable resources.

Thanks a bunch, Bryan.
