the 929 mod and others

I saw the other day about the 929 master cylender on the FC. I would like to know more about this. What advantages are there? and what is needed to be done?

Does it improve the feel and shorten the travevl?
I would also like to shorten the travel of the clutch petal, is there a mod for this? I have thought about using the petal kits from a True Choice catalog I have. They have all three petals on one bracket atached to the floor, they are very close together and don't have to travel far. they are the kind that they use in formula and other type race cars. What do you guys think about this? is it feasable?
try this

I also wanted to change to the four piston brakes. do I have to change my hubs and everything too? I just got some new rims and I don't want the five lugs any more. Should I just go with the big break kit from bremo?
thanks guys and gals

Id stay away from pedal kits like that, looks like a big project. You dont want to do too much home rigging to the brake system on a street car. Its just not safe.
If you have the 4 lug normal suspenion you need to convert to a 5 lug hub and brake system. Basically need to swap everything over.

Thanks guys.
but I only have the single piston calipers. My entire brake system is less than a year old. They replaced everything with out concent. All I needed was one rear caliper replaced, I dropped off the car and went on vacation for 4 days came back to get the car with a $1500 bill. I was pissed. they replace every caliper and rotor and pad. but didn't even change the wheel beerings. They used all mazda parts atleast but ever since then my brakes have allways sucked ***. I can slam on the petal at 20 MPH and the will not lock. they wont lock at any speed for that matter. the trouble ius I don't have much braking force.
I guess if I need to switch everything I will just get the Bremo big brake kit. it is only $850 if I install it.

by the way, if anyone is in Sikeston Missouri and your RX-7 brakes down, DO NOT TAKE IT TO PLAZA TIRE OR DAN'S AUT SERVICE!!!
