Does anyone know where I can get a set of these Button Bolts for the IRS?
The "buttonhead" bolt is a possible solution, but probably not the best one. Changing chassis fasteners is a complicated matter, as well as a major safety issue. There are lots of variables that must be considered (bolt material, diameter, strength, stress factors, fatigue life, sheer load, etc). The buttonhead bolt may not as strong as the factory bolt under all load conditions...and at least one person reported a buttonhead bolt failure.Originally posted by jdl1000

Greg - Do you have any more information on this button head bolt failure? Were the button head bolts in question acquired from J69gordon? Supposedly the ones offered by J69gordon were a few grades stronger than the OEM IRS bolts. Although there was some concern over shear strength at the head since the stock bolt has a collar and the button head does not.

Not trying to get in the way here, but the bolts J69gordon was selling were made by ARP in a batch of 50 to 100 sets. They were stronger than stock. There were others floating around that were inferior. I'm not saying the one that failed couldn't have been one J sold, but usually ARP stuff is top notch.....it should be for the money!

Not true.. They were provided by a local fastener supplier. ARP wouldn't touch them with gloves on. The bolts were unsuitable for our application. I know, as I still have a brand new unused set in my tool box. I'm the one who initially came up with grinding the head of the factory bolts.

So how much clearance is safe? Does the wheel/tire move left right at all?
There are 10.9 button head bolts availabe from www.metricMCC.com item # 7380, but they are full thread and that has to weaken the collar area?

but ac427cobra are you the one over at Corner-Carvers that was involved in the big discussion about brakes and rotors, and ended up doing custom rotors.

I have seen several references to AFS "extended reach" lug nuts required when running these spacers.
I contacted AFS and they informed me they don't have any "extended reach" lug nuts. Just their standard lug nuts. Are their standard lug nuts "something special"?
I have some 7/32" spacers finally on the way from Raysur and think I will need extended reach lug nuts?
Any and all help/advice will be greatly appreciated.

Yep, Ray is making spacers. See the last post on this page:

Yep, I'm the guy that had Coleman make me rotors for my front floating two piece Brembo set-up. Coleman's rotors are better and lots cheaper than Brembo. Before I found Coleman I was pulling my hair out over those damn Brembos!!:bash:

How AFS makes there rims you really need to use there lugnuts as the hole is significantly bigger then the stud size.
Here is a picture of there lugs compared to stock.
I am pretty sure there lugs will not work with stock rims.
I have undies 1/4" spacers on my car and haven't had a problem at all.
