Hello, Okay this is what's going on.. I saw a Hachi Roku, a 4 lug car, using TII breaks.. so I figure someone probably makes a 4 lug rotor that is large enough that I can continue to use my 4 lug hubs but upgrade to the TII calipers. Someone GAVE me a set of calipers but I don't have the rotors and I have someone looking for a mnfg that makes a 4 lug rotor that would fit the 4 lug hub.

Was wondering what the physical difference between the 4 and 5 lug front rotors is.. I know the 5 lugs have more surface area ie.. larger in diamater.. but is the thickness different as well?

THANKS!

 

For starters, if you lose 1 bolt on a 4 hub, the rotor has more room for play. Very unsafe.

 

The difference between the Front single piston 4 lug rotors and the 5 lug 4 piston rotors is the 4 piston rotors are about an inch and a tenth bigger diameter and 1/4 thicker.
