Two questions...
Anybody running the Rennline Wheel Stud conversion kit? Are they solid? I've had mixed experience with aftermarket lug studs and nuts in the past, including having aftermarket studs that actually snapped in two while I was driving the car -- it's no fun.
Also, I'm assuming that by a reasonable interpretation of the autoX Street Stock rules, these would be an allowable modification, right? The rules allow for aftermarket wheels which require different lug bolts, so lug bolts aren't off limits -- and a lug stud and lug nut are really just a two piece lug bolt, right?
