BBS RS wheels for 308 GT4

HMMM--- I recall seeing spacers used on March GTP cars back in 80's never had any issues with them

 

Hmm, is this really so? Here's my thinking:

If a spacer is designed & machined properly, it will sit very snugly on the same hub rims the wheels fit around, & the spacer will have a similar rim for the wheel to sit on. Thus the radial forces on the wheel would be transferred directly to the hub. There should be minimal additional forces on the wheel bolts.

Some spacers just have flat front faces & a clearance groove for the hub rims. These should be avoided as they would indeed put a lot of shear force on the bolts.

Axial forces on the wheels are going to put the bolts in tension in either case. I can't see how spacers significantly add to the tension.

CAVEAT:
I have never worked with spacers, so this is theoretical & based a conversation with Atlantaman, & some reading a while back. Does anyone have more specific info about spacers & the load they put on wheel bolts?

BTW Atlantaman,
I wish I'd either remembered our conversation, or seen this thread a couple of weeks ago. I just shelled out big bucks for a set of Superformance wheels.

 

Verell--I have to come back to Danbury in 2 weeks--I might drive up in the 308

 

There is nothing wrong with using spacers if they're done properly. See the FAQ at Ronalusa.com 's web site.

Charles,

What about those wheels? What are they and where did you get them? What year Mustang did you spec. to when you made your spacers?

Thanks

 

atlantaman, I too wonder about the manufacturer of those wheels.

 

still waiting.....
