Brakes?!?
 

Well I have hunted around the net for a little bit trying to see if there is some kind of big brake kit for my 88 turbo. I have come up short because it seems everyone who makes a kit for supra is years 93-98 which doesn't help me out, and to boot there supra expensive like close to 2500.00 for all 4 wheels. I have since figured out a way using a toyota 4runner 4-piston caliper and a roush mustang 13" rotor cross-drilled and slotted because mustangs and supras have the same bolt pattern. In the rear I am going to put the stock 10" rotors on from the front for more surface area and am trying to locate a 2-piston caliper for that set-up. I was wondering though if I need to upgrade my master cylinder and brake booster to keep up with adiquate pressures to feed the beefier calipers all around? And if so is there a place where I can buy such a thing, or could I just go out and get a brake booster with matching master cylinder off an old truck to keep up with the needed pressures?

I don't know much about the supra brakes, but I can't imagine the 4runner ones are much bigger, at least not until 2002.
I have an '85 truck and know about the older 4runners and trucks, the master cylinder isn't any biggger. One from an fj80 should bolt up, but it has the same size bore (1"). You can get those from marlin crawler, they sell them for 4x4's. (say that 3 times fast!) They also sell calipers for 86-95 4runners if thats the correct year to fit on the MKIII.

Thanks bro I definitely look into that. Cheers.
