Re: What brake upgrades work with stock 18inch Bullet wheels?
Steeda offers two brake kits on their site that have 14" discs. One is the Steeda kit, the other is Baer for less money. I would call them to make sure they fit, but the GT500 has 18" wheels and 14" discs standard. Jegs has replacement rotors that fit the stock calipers, they are slotted which should help, but I don't know how much better than stock they would actually be.
