Hello... I have a 91 convertible and it appears I have 4 piston calipers on the front and single piston on the rear. I was wondering if anyone has replaced the rear with the 4 piston calipers ? Thanks

 

no. and there is no point.

 

The point is that the front have the Mazda logo and the back do not so I wanted to have same all around the car.

 

If I remember correctly the rear calipers are not aluminum either, theres probably an unsprung weight advantage to the aluminum 4 pot calipers.

However you won't have parking brake facilities with the front calipers on the rear. Wilwood makes a lightweight mechanical caliper for parking brake usage which you could probably make work.

I have wilwood 4 pot calipers all around on my fiero with the mechanical parking brake calipers on the rear, it's a nice setup.

 

definitely not worth the trouble IMO. Unless you have incredibly revealing rims, no one sees them anyway.

 

your not joking are you? i hope that you are.
