Is the brake master cylinder on a 92 gt celica good enough to puch the jdm "celica" 4 piston calipers? If not does anybody know one that will that is also a direct bolt up on our cars?

JDM Celica 4 pot? Are you thinking ST205? Those, iirc, aren't a direct bolt on.

Yeah srry i ment piston not pot, but anyway i know i have to tap the hub bigger to allow the caliper to fit, but my question was if the brake master clynder on a 92 gt vert with rear discs would properly push the front st205 calpers. The reason i ask is bc im not happy with the stopping power on the new vert.

I honestly have no idea... You try swapping pads & fluid first? Honestly stopping on the street shouldn't be a problem.

Yeah i swap fluid and draned the fluid, but i guess im used to the ST after the brake swap

Yeah I think the 92 Vert has the larger AT style brakes but I can't be sure.

So after a little more research i found out that the inside of the caliper needs to shaved down a little to clear the rotor with a 5th gen hub,but the caliper has no clearance issue with the 6th gen hub so i ask will the 6th gen hub directly bolt on to a 5th gen celica?

Ok, so after finally getting a day off i did a mock up with the 4 piston calipers and noticed that the pad didnt touch the rotor untill 4 mm deep from the bottom of the rotor up. So now the plan is to get the rotors cut down in height by 4 mm and do another mock up.

Even if it's down 4mm it won't make any problems.

How are you mounting these bracket wise?

No bracket, the caliper bolts up to the 5th gen hub but bolts behind the hub.

Interesting.

No... so they're down 4mm from the top, what does it matter?

Oh srry, it would give the caliper the room to reach the bottom bolt hole on the hub w/o the rotor rubbing the inside of the caliper. Bc as it stands now the caliper is a hair off from being able to use that bottom bolt hole bc the rotor is in the way.

I will enjoy the write up on this one.

So in order to run with these calipers i need a set of wheels that are at least 16x7.5 w/ a 35 mm offset. So my question is does any one have a suggestion as to what will work in terms of different sizes and different offsets? The max im willing to go is 17 and the minimum is 16

KoreanJoey

17x9 :)

KoreanJoey

Oh, wait, narrow body?

My bad. a 16x7.5 will fit. The ST205 wheels fit nicely on my GT.

I was planing on swapping to the widebody front fenders off of my old ST bc the vert fenders are shot. I would love to go 17x9 but im not sure if that will work in the rear of the car bc it would still be narrow body in the rear of the car.

Grimmy, on the front fenders, check out the Captain's write on Dutchess. They'll work but it's not straight swap. John's got a good write up on putting the widebody fenders on the vert. Some modification is necessary.

^ thanks for the reminder nitro i forgot captain went widebody on dutchess.

Ok so after a little more research i found that the 7th gen gts 16inch wheels have no clerance issues with the st205 calipers, so the plan is to source a gts wheel and do a mock up with that wheel and see what happens. Worse that can happen is i buy a full set and run with a wheel spacer for a while.

The clearance between the stock 92 caliper bracket and the 15 inch 7th gen wheel isnt much.

The width of the stock 92 gt caliper with the bracket is about 6 3/4 inchs

And the full width of the gt4 calipers is about 155 mm, so in theory the 7th gen gts wheels should work w/o a spacer

ok so i found a 16 inch gts wheel and as u can see everything fits inside of it, i would have done a better mock up but my jack finally gave out on me after 10 years, so ill be pickibng up another one come payday and get everything mocked up with the wheel on the car :) but now im thinking a small spacer is required bc of the word "celica" on the caliper my stick out a little to far and hit the caliper while the wheel is turning, but we shall see come payday :)

Is this the ST205 calipers.... with the ST205 brackets? and the ST185 Disc?

I like where this is going but we need some more info...I'm not sure exactly what you are doing.

Not a criticism, a request for more info

its a st205 caliper with the st205 rotor and st205 brake pads. no brakets going to have to tap the factory hub, and cut the rotor down but luckly the pad doest touch the outside of the rotor, pics of my resent mock up are coming soon, unfortnaly i will need bigger wheels for the calipers to fit, or get some spacers

the dust sheild will have to be cut down or removed all together

next the rotor will have to cut down to allow the caliper to fit properly, but luckly it doesnt need to be cut down much as you can see the pad doesnt touch the outside of the rotor.

next is the gts celica wheel isnt wide enough to clear the caliper w/o having spacers fitted.

and last but not least the size differance between the rotors is huge. the gt4 rotor is under the 92 gt rotor

the bolts from the stock caliper bracket that hold it to the hub looks like it can be used to hold the gt4 caliper to the hub after the hub get tapped.

i also found out that longer wheel studs will be needed, i also desided on getting new wheels instead of running spacers with the gts wheels, i how ever do like the tight look of the 16 inch wheels around the caliper so i guess the hunt is on for some 16 x 7.5 inch wheels how ever 17 inch wheels are not out of question. so stay tuned true beleivers!! :)

Having some room for heat dissipation is always a good idea.
