mr2 / gt4 / corolla caliper interchangeability

[200Boy]

I have ZZE123 calipers

fit perfect with the ST185 278mm rotors

I have some ST185 singles on the way
I also have some ST202 twins on the way

research is great
I'm going to try and mix and match to get the big rotor twin front combination

I could hit up TOCAU to see if anyone has any 2nd hand ZZE123 rotors around the traps, but personally I'll rather use the correct centre bore initially as that's the vital measure for rotor balance hence the DBA743s

Any updates on this? I'm sick of reading over the same info and would like something new

I have the ZZE123 calipers bolted on with the ST185 278mm rotors (DBA743)

ST202 did not fit over the rotors so I did not use them.
I never received the ST185 singles to compare.

I also have SW20 calipers on the rear with AW11 front rotors spaced with a 6mm spacer.

Tested them out on the track last week and after some initial locking of the brakes while the tyres were cold they performed brilliantly all day... 200km worth of track time!

Pads are Ferodo DS2500 on the front and regular Bendix GCT on the rear


This is all for an AW11....

I know this is a very old thread but -finally- I have gotten around to doing something with this. I've had the hubs machined/sleeved to a 55mm hub spigot bore and hub mounting brackets and knuckle mounting surface skimmed 2mm each (moving the calipers inboard 4mm). I already had to replace my wheel bearings so it wasn't such an issue to separate the hubs/steering knuckles. Using JDM Group A/ADM S2 ST184 single piston calipers (that accept a 278mm disc), ZZE123 rotors (direct bolt on) and everything works My stuff is off getting ceramic coated now but I'll get photo's when I've got everything assembled (as I'm heading off for up to 3 months this may be some time).
