I owned mine since 78 (RX4) and I worked at the dealer for some time the 4 handles a pit better both go like rockets just dont try to stop to fast the last few years I've been up gradeing the suspions to 2nd gen front and rear DAM now it's fun to drive

 

I've been considering the same upgrade for my rx3, wondering how difficult it would be to put 2nd gen front and rear brakes on it. I do machinist work so any modifications wouldn't be a problem.

 

I dont kown about brakes alone I did the coplete suspenion the full meal deal so the brakes came whit it lots of sheet metal work

 

You should post pics of that. I was dreaming of doing the same thing.

 

I would like to see pics. hmmmm I have plenty of donor FC's

 

wow, how hard would it be to do this to an old mazda? I would love to see pictures too.
