Hello peeps Quick question for ya all.....ive recently picked up my old skool BBS 8.25 & 8.5j 17" splitrims......the chap said im gonna need grp4 studs...after having a closer look I see what he means as in the bolt holes are much deeper...ie approx 20mm from hub seat to lowest point of nut taper seat.....so where can I can some?? Not too sure what the grp4 spec actually is, is it just a longer stud, or more to it than that??

Cheers in advance,

Stu
