Big breaks on a GT with the "frankenstein" axle set up, Needing help figuring out what breaking system(s) will work Options

[Detatch]

OK, so first off I'm swapping in a 3rd revision 3S-GTE into my 94 GT. I'm also swapping the E-153 LSD transmission, and the hybrid "frankenstein" axle for the front, consisting of the inner portion from the 93-95 MR2Turbo, and the outers from an st185. The rear axles are staying the same.

My issue is, i want to put larger breaks on there. Will the st204 rotors and calipers i already have (or rather if i get larger st204 rotors and calipers) work if I'm using the st185 outer axles?

Axles have nothing to do with your brakes

right, but i'm worried the part (i'm not exactly an expert on the axles yet) that bridges the axle to the rotor will accept that axle.. if it will i should be able to use the st204 rotors, and therefore the st204 calipers....

i've heard something about there being a 1mm difference in the rotors and/or calipers (still not clear on this), and i'm concerned that might be due to that piece being different (and needing to be), which could mean a difference in how far the rotor sticks out (meaning i'd have to change the calipers)....

and changing the calipers would mean changing the entire breaking system (from my understanding which is probably wrong)....

sorry, i'm still new to the technical side on cars... 3 weeks ago i didn't know the difference between a turbo and a supercharger, or what naturally aspirated meant, now i've got the entire swap and almost all the upgrades (besides this little break system issue) mapped out and have a pretty good understanding of what each part is, does, and how it works...

ok, i know you are from Japan but its spelled BRAKES.

now the part that the rotor + caliper bolt on to, are still what came on your car you use the same brakes.

The part where the brakes and the axle meet is called a KNUCKLE. You should still be using your OEM knuckle and so yes....your axles have nothing to do with your brakes and you can still use the ST204 calipers and rotors.

awesome, that's EXACTLY what i was needing (and hoping) to hear...

incidentally: i'm not FROM japan, i'm just in japan... i just suck at spelling..

ok, NEXT issue: how to delete a spend topic....

The fitment issue you mentioned is this: fifth-gen hubs (the centre spinning part on which your wheels and rotors mount) are less than a millimetre larger than their sixth-gen counterparts. Or to put it another way, the hole in the centre of sixth-gen rotors is just barely too small to properly mount on fifth-gen hubs.

For 5SFE-powered Celicas:
Front rotors
90-91 255 mm diametre, 22 mm thick, 54 mm centrebore
92-93 277 mm, 25 mm, 54 mm
94-99 275 mm, 28 mm, 55 mm

Rear rotors
90-93 269 mm, 10 mm, 54 mm
94-95 269 mm, 10 mm, 55 mm
95-99 269 mm, 9 mm, 55 mm

Here's the trick, as far as I know: hubs can stay with the knuckle. This is how people do mass swaps -- they disconnect the knuckle from the axle and strut and move the entire assembly, brakes, hubs and all, over to the new car.
