1990-2005 Miata brake clearance notes:
- Clears factory brakes and factory optional sport package brakes
- Wilwood 11" big brake kit: requires 5mm spacer
- Goodwin Racing 11.75" V5 big brake kit: clears without spacer
- StopTech 11" big brake kit: clears without spacer
With any wheel Konig develops with Flow Forming Technology, the end result is stronger, lighter and offers greater elongation and shock resistance than a traditional cast design.
Note we STRONGLY recommend our numerous upgraded lug choices with any of our new wheels, stock lugs too short and fat and will scratch these wheels. Unlike the short and fat stock lugs that will result in scratching new wheels, all our replacement lugs have the socket tool bottom on the lug rather than the wheel surface, and are longer for more engagement with stud surface so they also stay tighter.
No fender roll needed for any 1990 through 2005 Miata if you have at least 1.5 negative camber and a reasonable size 205/50 tire such as the popular Continental Extreme Contact Sport. We run MORE than 1.5 negative camber in all our toys, consider 1.5 negative camber a minimum for good handling.
