What about SFX? lol! I decided against the studs. Just dont like that idea the more I read/think into it. http://www.sfxperformance.com/parts/GOR17142SDBC-20.htm Found these. They're Gorilla brand. Pending what the dealership can offer these may be the ones. Then again, I'm starting to re-think the 18" idea. They look f'n sweet.... BUT, so do the factory JCW wheels. So many choices! It's not fair.
If I were to race it often and switch wheels out often I'd go that route. I'm ok with buying some good bolts instead of installing studs. I've had wheel studs all my life, something different is cool. Also, the studs come in different lengths and I'm not sure what to get. I'm ok with buying bolts and having a autoX set and a daily set. If I go stud route I gotta get nuts for the factory wheels too so really I'd be spending more to achieve the same goal. Ultimately I'll have a set of light racing wheels for autoX'ing. This is just a "for now" kinda deal with the 18's. If I get more into the AutoX thing, this will be my first year, I'll think about installing the studs.
My thought on studs & just mine. When I first bought my MINI I installed studs. When tightening the wheels I felt a couple of them stretch. Not a good thing. I bought cheap arse studs so that may have been the problem. Should have bought them from Turner at 5 times the price. I then bought a couple of wheel hangers from fleabay. Made changing wheels much easier. I've never had a wheel fall off on street or track. A couple of these will help. M14X1 25 Stainless Steel Lug Bolt Guide Wheel Hanger | eBay
The issue I had with switching to studs and bolts, are they are always the same length... So they might look good on some rims...but be too long for others. With a set of lug bolts...they always (IMO) look right, both with the OEM rims that exposed bolts, and most of the aftermarket ones... And funny thing is I found I like THE BOLTS...Faster to thread when I change rims....just hold the rim in place momentarily, hanging it on the hub centric ring...then put a bolt through a hole...rotate the rim a bit and bam...bolt lines up..finger tighten..grab the others.... Quick one arm, one handed move.... No stray nuts to have roll away...
