are there any year corollas with the 4x100 lug patter with rear disks?...im trying to find toyota cars with rear disks that will fit my st celica....and what all would i need for this swap

1988-1992 Corolla GT-S has rear disks, 4 x 100

What year is your Celica ST?

I have a Celica GT, I wanna do a disc conversion too.
My bolt pattern is also 4X100. From What I know is that AE 92 also has 4X100 with rear disc. But I am thinking is that possible to change my bolt pattern to be the same as Celica GTS. B cox GTS they have 4 wheel disc brake.

Actually it should costs less to change my rear drum to rear disc from AE 92 than to change bolt pattern to 5 nuts from GTS, right?

Any suggestion? and ideas what can I do to upgrade my brake become 4 wheel disc?

i think what he was trying to say was the st165 celica gts is 4x100, with disc brakes. which it may or may not be, im not sure.
but the mr2 is 4x100 with disc brakes as well

rear discs stop better and displace heat better than drums

Den · 03-04-2003, 09:19 PM

yep yep that's right

but is that possible to put AE92 or MR2 MK1 's rear disc brake systerm on my car?

how much does it approximately cost?
have anyone done it before??

I got rear discs on my Camry. I haven't really noticed a diff. from my past two cars that had drums.
Maybe in emergency braking I would notice?

Well you might get problems with brakes being too cold especially in winter and brakes dont work good when their too cold. Plus you might run into a problem with the handbrake not holding. Most diskbrake cars have a small drum in the centerhub where the handbrake holding shoes are. The AE92 disks dont.
Plus in toyotas the rear braking power is only ~15-20% power from the front, toyota uses front biased braking to make the car slow down predictably and without loss of control.

Den · 03-05-2003, 12:21 PM

I know about the braking portion. The front is the key to stop the car. But if I changed it from drum to disc, isn't it that the rear will have better braking?

Anyway, my personal feeling, my Gen 3 camry with rear drum compared to my gen 3 v6 that has rear disc. The feeling is totally different, much better breaking result~

Back to my question, can anyone tell me is that possible to put AE 92 or MR 2 rear disc brake on my 86 Celica GT?

Flashmn · 03-05-2003, 12:32 PM

No because the proportioning valve will still divide the pressure on the front and back.

Den · 03-05-2003, 02:57 PM

How about the breaking result?
even if i use disc, it will still be the same?no better stopping distance?

Flashmn · 03-06-2003, 02:21 AM

if the disk doensnt heat up, braking is minimal... Because brakes have to heat up a bit to have the pad bite. For example really skimpy rims in winter = disk is too cold due to airflow that brakes wont engage as quickly as in summer. Too hot is another problem, but on regular driving I dont see how you'd boil your fluids if they are fresh.
For normal city driving, I'd probably opt for drums. Track racing, carshow (disks look better) and maintenance (disks are WAY WAY WAY easier to maintain), well I'd take disks :P

Flashmn · 03-06-2003, 02:23 AM

And I seriously doubt the stopping distance would decrease significantly. If you want serious improvement, just update the front brakes. Because if we talk about full lock braking, its much to the tires and weight of the car that determine how fast it would stop.
