Hi guys. I want to use the larger 03 brake disc on my 99 WR but I need to bump the calipers out. Is there a spacer on the market I can use?
Also, How did Yamaha do this? Did they redesigne the calipers or did they just change the mount? I see some stock mounts on that online auction site so if they will work Ill pick them up.
HELP! My 99 rotors are shot and warped and when I hit the front brake I get a nasty head shake :yikes: .

front rotor is the same diameter 250mm - solid or floating

Rear on the pre-02 bikes is 240mm. 03+ is 245mm.

You can run the 245mm disc on the earlier bikes without modifications.
