I got my hands on some 7/16" GM ARP Wheel studs that are .480" Knurl, press in. (They are left over from my bro-in laws project) Does anyone know If I can drill the Midget Hubs to accept these and what size I'd have to drill them to? The rear hubs will be WC dbl bearing hubs.

Do I need a special hardened bit to drill these?
 
Yes you can do it no problem, I use Winner circle 7/16 long wheel stud, probably alot like what you have and they have a .480" knurl, I use a 12mm drill bit in the drill press or mill for this, 12mm in.4724", which is about perfect for a wheel stud knurl, you more interference than a regular press fit. Done this many times before.
 
Scott:

Yes, a common HSS drill bit will do this no problem.
 
yeah, the big deal is to keep your drillings VERY straight. I would recommend a press to install the studs in the hubs.
 
""""""The rear hubs will be WC dbl bearing hubs.""""

order the hubs with 7/16" studs installed or drilled holes 15/32".


The aftermarket studs are almost 3" effective length which might be too much with the spacer your going to ever use? you might want to trim them B4 install.
 
On the rear hubs, the studs will have to have a corner nicked to not interfere with the radius on the rear DB hubs. With that Spridgetech Body work depending on your wheels backspacing you'll need spacers with with 13 x5.5" Revloutions with a 3.5" backspacing I used 1/2 WC spacers, with the Superlite 4" backspacers, I used the 1" WC spacers, used thier studs as well, the Spridgetech flares are huge, so spacing the wheel out and gaining more track is a option, does your group have stated track for your car in the rules?
 
2" would be awfully narrow! /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
More like 50.2" front, and 48.7" rear.
That was the track width for F Production in the 2007 SCCA GCR, Production Car Specifications list.

2" track?!?! It's a Crudley "White Liner"!!! (obscure KDKA/Rege Cordic reference).

The Crudley was a car so narrow it could be driven in the middle of the road... for those who seem to insist on doing so.
