Im worried about tire size on the rear and rubbing. Any hints?
Ans): I have the 13 x 5 wheels. I had them on stock setup with exception of the panhard rod and lowering. The rod keeps the diff. from sideways drift and is highly recommended. I had 195 x 60 SR 13’s on it that are pretty wide (about 7″ of tread), and it did rub a little. I have installed the finned alum. drums with 3/4″ added width built in (expensive). This gives back track same width as front which is good. Spacers could be used (say 1/2″) but I would not recommend it unless you go to larger 7/16″ lugs. Even then, you have to watch lug nut torque. Best solution is the mazda rear end conversion that if done right gives the right spacing, disk brakes, limited slip (a must) and is bullet-proof. The cost is very reasonable by comparrison to what I’ve spent and I don’t have rear disks. Just takes serious machine work and welding, etc. I’ts what I would do again, or if I have one more bit of trouble (don’t expect it since I’ve done everything that can be done to a stock diff.)
