Nice find. Looks like a quality part. Do you have any photos installed, i'd like to see if the shoulder pops through the brake hub mating surface?

There's two things that concern me just a bit about those is the knurl diameter is less than stock, not that .2mm is a deal breaker (OEM is 16.1mm) , but with a knurl designed with such tight tolerances i'd hate for you to spin it in the hub. Second is the shoulder length looks to be longer than stock.

I'll snap some pictures when I get everything put back together. I still have the front struts out from installing new springs.

When I measured the knurl diamater on the old ones that I knocked out, I got ~ 15.30mm...

I also gathered this information from ARP and PTC... The ARP part numbers are listed for the 6th Gen Camaro.

A little protrusion. But, everything fits just fine.

I run a square winter setup w 7mm spacers up front.

I just cut the "nose" off a set of arp studs, makes them about stock length but more threads so the studs can be used for the stock setup too.
