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.

you are missing the most important part of the disc

offset, the offset is critical, too deep and it'll rub against your ball joint during cornering, not deep enough and it wont line up with the caliper, which you can solve by shaving some from the caliper mounting points to line it up, but go too far and you'll have a problem fitting wheels unless you go with some weird offset like in the 20s lol.

you need to get a set of calipers, bolt them down using stock disc, then take measurements of how far off from the stock disc the caliper's center line is in relation to the center of the disc. that way you'll know what's the " ideal " offset you'll need on the disc, if that number is 57 mm or higher, you'll need to shave off material from the bracket to bring that number down to avoid contact with the ball joint. if it's less than 57 mm, you are golden, all you need to do is find the right disc.

" hint "
there is an Audi disc very close to those specs you posted, but can't remember the offset on it.
