I am trying to fit a set of 20's on my Touring model Z (no brembo brakes). Thing is, there is this black projectile sticking out about 1/8 of an inch that is preventing me from puttin the front wheels on. On the stock wheel there are holes so that this projectile can fit into. The black projectile has a brass like nut in it, and is located inbetween 2 of the studs... can anyone tell me what this is, and how it might be possible to fit my wheel on?

 

it's there to stop someone from putting the rear wheels (which have wider tires) on the front of the car.... if you are putting aftermarket wheel on the car, you need to remove it.

 

If you are asking about your legs (STUDS) please go to z-chicks.com for that anawer!!!! LOL
