This is the 3rd time I have broke off one of the gears on my FD. My rear end and axels seem to be bullet proof now that I have a Kaaz and Chromoly axels, but what do I do about the gears? What do the big dogs (Ari, Dee, Dan S., ect) run so they don't break?


Would I be better off selling the Kaaz and going with a Ford rearend or maybe cryo freezing the gears? Any help would be appreciatied!

 

Also, where is the best place to buy? I figured I would buy from RX7.com since they know what they are doing and shipping is quick.

 

From what I have heard cryo treating the gears is the way to go. But I do not know to what spec to have them done to, because I'm sure you can go to far and they become brittle.

 

A few teeth were broken on the gears, but it looks like the teeth also took out the bearings too. Anyone know how much they run from Mazda?
