Default ARP wheel studs

Does anyone know which ARP wheel studs we need? Looking to possibly run spacers and I need longer studs.

Only thread I could find regarding ARP wheel studs... Are these too long to work with "normal" wheels - i.e. no spacers - and closed-end lug nuts? Need the upgrade for track-abuse strength, not the added length. Thanks!

I have the ARP studs installed and would guess that they are indeed too long to be used with the oem wheels & closed end lug nuts, though I haven't actually tried to mount 'em. I have a large collection of the oem style lug nuts from other Toyotas which could be used. The nuts from the rear of an SW20 Mr2 are long enough to work without cutting the end off.

OEM studs are 36mm from the back of the hub to the end of the threads. ARP says these are 2.600 inches, so 66mm. That's quite a bit more for closed lugs like ours. Hub face thickness appears to be 8mm.

The OEM lugs have 36mm of thread total with 12mm from the nose end to the washer. OEM rim face thickness is 15mm. So there is 28mm of OEM stud sticking out of the hub face. There is 9mm of room left in the OEM lug for additional stud length with OEM wheels and studs. You'd have 21mm of stud preventing you from using closed end lugs with the ARP studs installed.

Thanks guys. I'm just gonna re-use a stud from one of the OEM front hubs I just replaced, and hope it's not a recurring issue... Time will tell.
