That's interesting. But it's not really an upgrade. Could be a downgrade if it messes up the stroke/pressure/assist etc.....
I wonder what size bore the rx8 master cylinder is. The 929 is a 1" bore. The S5TII ones are 15/16" bore. I like the 929 master a lot. Full brakes is like 1.5" travel. Then it's rock hard and you get to modulate the brakes based on the pressure/effort you apply on the pedal rather than trying to move it 1 mm more or less to modulate.
i know the tribute is a 1" master too, i dont know the sizing on everything else, but an s5 t2 booster is not exactly easy to find..... but there are a lot of mazdas that share the same booster to firewall bolt pattern, and the rx8 stuff is CHEAP. the s5 t2 booster is like $300 and the rx8 is like $90

You dont follow directions. Bench bleed the master, bleed from the furthest point to the closests point. Rock solid brakes. Simple.
did that twice! 2 different people! 2 seperate occasions!

does your car have a proportioning valve?? my 88'vert has one right next to the master. it is the only part i can think of that has not been covered already in this topic. this is very important in distributing pressure between the front and rear.
