Lugnuts holes: Lugnut holes could be deeper. I can only get 5 rotations before the lugnuts are torqued. I would prefer 8+. Distance between the lugnut face (engaged in with the cone) is 12.3mm, while on my Enkei PF01SS, this distance is 9.2mm.
I calculated out the minimum ISO thread engagement--comes down to 6.5 turns. I'm getting 5. The ISO minimum engagement is the minimum engagement necessary for the bolt to fail before the threads. So likely, the threads will fail first with this few threads. That isn't to say it will fail in use however, but it isn't ideal.
Additionally, pretty heavy powdercoating in the lugnut holes--torque and remove the lugnuts a couple times, blowing out the lugnuts holes in between cycles. The coating will flake off the aluminum until it's all gone and you can get proper torque to the aluminum.
I'm going to use Gorilla "Extended Thread" lug nuts just for piece of mind, instead of going to longer studs or the like. The extended thread section doesn't have the hoop strength of the actual nut part, but there are ~5 more threads engaged. I'm OK with that. These guys: http://www.amazon.co...0?ie=UTF8&psc=1
I drilled the lugnut holes out slightly to allow the "nose" of the Gorilla Extended Thread nuts to fit inside.
To date, I haven't had any failures, so I guess this works!
Still flipping through the main thread on another forum, but this caught my eye in his initial post:
It reeeeallly doesn't even look like a forgestar to me, either that or it's an OLD model.
Either way, any wheel can break. Gotta inspect Forgelines, Forgestars, and AMR's all the same.
Yeah but this guy was jumping curbs on every corner. That's for wheel to wheel racing, not track days. When your doing that it's just a matter of time before an aluminum wheel is going to fail. The message here is check your wheels thoroughly after each track day. Period. Inside and out.
Also the corner just before the wheel broke he jumped a curb in a high speed corner that he had no need to. He had plenty of track to carry the speed with out that 2' of extra real estate that he took. Point being, how many other times did that happen in 14 track events. I believe the wheel manuf. is getting called out when it could be driver/owner lack of proper maintenance. Jmo
And I'm not calling any body out for lack of maintenance at all. As the old saying goes "a bought lesson is the best kind"! And most of us learn the hard way.

Those guys are crazy! I thought they used steel wheels, though. You know. Because crazy Aussie driving.I know the Australian V8 Supercar guys jump curbs like mad but not only do they inspect their wheels they also replace them at regular intervals.

I'm with you that hub does not look like a Forgeline
