do i need extended studs to run slicks? i got some slicks on my steelies just making sure before track opens for me this coming weekend.

im pretty sure if your using some slicks that are mounted on steelies, that you don't need any extended wheel studs. They are mainly used for wheels with a wider offset, that require longer studs

TehMan

yeah its for a wider rim...i have them on my civic...

miata wheels


extended lugs for track use

i needed them to run bogarts, plus a spacer to clear the caliper.

it is a rule at most tracks that extended studs be used with slicks. but a lot of tracks dont enforce it...

How many are actually using extended studs and reason why? Being wheel size or caliper clearance issues.

bogart wheels require them.

i think also when you get to a certain e.t., you need the stud to protrude atleast half the width of the stud through the nut. my NHRA rulebook gets here this week.

thats what i thought but i never got yelled at for not having them on my buick. but that was 10 years ago. damn that was a long time. and i didnt have c-clip eliminators either he hee.

dunkd

yah i think its one of those rules most tracks dont enforce.

go to nhrasporcompact.com they have the rules there look under general regulations
go to wheels and tires
read rule under 5:2 that will answer your question

The thread engagement of all wheelstuds to the lugnut must be equivalent to or greater than the diameter of the stud. Length of stud does not determine permissibility; length of the engagement between the stud and hex portion of the lug determines permissibility.

from what I understand. aftermarket wheels with slicks need extended wheel studs with open end lugnuts. and 11.49 cars need them as well.

i'm also running 13x8 bogarts with a .5mm spacer. extended studs deffinatly needed.

I reccomend the ARP's.

Some dragstrips may be stricter than what they NHRA rulebook says, but I just finished reading all 3 .pdf files on NHRAsportcompact.com and they all say the same thing as what I quoted above--and that includes all classes from ET bracket to Pro RWD.
