4runner brakes on gt celicas, big upgrate and not expensive! Options

[diegohiga]

I was doing a reserch and apparently 4runner brakes with 4 pistons (non sport) version fits on a gt front rotors, And the sport version fits gt4 rotors. I think the brakes have to come off from a 95-02 3rd gen 4runners and will bolt on perfectly with no modifications.
Now my question is if they fit proportional valve needs to be modified? Becsuse it will be pusshing 4 pistons instead of 1.
If anyone has more info about this please post it here.

brake master cylinder is the same in GT4 / GT/ ST/ etc

as of right now I have GT4 proportioning valve, front brake system, rears are yet to be installed waiiting on some small parts.

for a street car with some mild road racing exposure, a proportioning valve is enough to tune the brakes, on real racing they use a dual master cylinder with a dedicated chamber for front and rear with a sliding rod that adjust the pressure given to each, this is the most efficient and very easy to adjust even while driving, but that's assuming the driver knows what and how to compensate for little things in the car, this devide is used to compensate for different levels of gas, change in track conditions etc. very very tech stuff that us street drivers wont really use and / or fully understand.
