Call Optimum Performance. They gave me a pretty good estimate of when their last batch of studs were coming in. I just kept checking their site around that window and was able to grab what I needed
I've got OP hubs with their GT4 stud arriving later this week.

OP told me they had GT4 studs, but it was cheaper to buy complete OEM R hubs.

That was my main interest in GT4 studs (along with fact that my first 350R hub order got cancelled and I got frustrated). I'm not sure if I might want 35mm spacers.
I'm running 35mm spacers, but that's with 11.5" wheels and 315 or 325 tires.

No cage or bar. I use Schroth QuickFit Pro harnesses which are designed to be used in vehicles without a roll bar. I added anti-sub straps that attach to a bracket made by a TMO member (I sit on them). I use a HANS device with the harness.
Where did you buy your anti-sub straps? I've got 4-point Schroth harnesses and want to make it a 6-point system, but can't find the Schroth anti-sub straps at any of the online motorsports stores. Thanks.

Never mind, saw an HMS link in another thread: HMS Motorsport » Sub Straps
