I recently installed a Raybestos 15/16 MC for a 91 EX on my 89 Si hatch and it fits without modification. Just FYI. I would use it over a prelude since the lines don't need bending. Good info on the BBK though OP.

They fit with stock em1's. I am running that exact setup on my 93 si.

95 Legend GS dual piston calipers
Mini cooper rotors
94-01 Integra Knuckles
Stock 2000 Si rims

No wayyyy thats awesome! So any civic/teg with the 10" setup just needs itr or legend calipers and brakets with mini cooper 11" rotors and blam, big brake kit for like $150-200 or so and they even clear factory 15" wheels. This is def on my to do list.

Sounds like you have a defective brake system. By any chance, was the car converted from a drum brake setup?

Rear brakes do much more than anyone gives them credit for on a FWD Honda. they do about 20% of the work, and when you've only got a finite amount of grip, if your rear brakes aren't working then you're going to be braking earlier than the guy with 20% more brake force at his disposal.

In fact, it actually gets worse than that, because with 20% less brake force you can only brake at say .8g instead of 1g. This means less forward load transfer, which means less available grip before the tyres lock, so then you might see performance reduce to 70%.

Let's also not forget the rear suspension design on these cars which is designed to react brake torque, affecting toe angle and trail taking stability. There's also kinematic anti-lift, which stops the rear wheels decambering and losing grip.

If you think you back end feels light with updated brakes, it's because they're not doing enough, not because they're doing too much.

I would always upgrade the rear brakes. Front bias just make my EK4 worse.

Double post.

nice
where you get hawk hp + from

Sorry to bump an old thread but is this information completely accurate?

The centerbore on the mini rotor is ~64mm.

The civic rotor centerbore is ~61mm.

Which means the rotor is no longer hub-centric.

Although it will "work" I think really a hub ring should be used.

Does anyobody have a source for the proper size? I'm looking for some.

I know a few years ago BrakeExpert was making them but I don't know if he still is.

In my research I found that MG ZS 180 rotors (available in Europe) are a better match than Mini Cooper's, in terms of center bore, stud diameter, overall diameter, retaining screw holes, etc. Those Rover/MG cars were Honda based.

I haven't been able to test them yet because I can't get the screws holding the old rotors out. I will let you know once that happens.

use an impact screw driver

Found on eBay UK - PAGID Front Brake Disc - MG MG ZS 180
Vented - Studs 4
Disc diameter 282.0mm
Disc thickness 25.0mm
Overall height 44.4mm
Centre diameter 64.1mm
Minimum thickness 23.0mm

The MG Zs is a V6 with a 2497ccm/177HP engine, fwiw.

Awesome writeup! Thanks!

I do not have this setup, but the person who posted this was referring to Integra hubs, which are 64.1mm. You would indeed need a hub ring if you want to use this rotor on a Civic hub, or just upgrade to Integra front knuckles/hubs like the OP did.

Has anyone confirmed that the MG rotors work?

The Mini rotors ARE hubcentric but they do slide forward and backward due to the larger stud holes than on our Hondas. I'm sure the brake disc slide back and forth during sustained breaking and ABS lock out.

For the track, unless the MG rotors work, it might be more reliable to use redrilled rotors rather than stock Mini ones.

what a great bolt on affair!

Better late than never I guess: yes the MG rotors work great.

umm think ill try this and hope they clear my 13 wheels for slicks

here is the way i have done on my 91 DX

from stock 9.3'' to 11''

i keep my oem 9.3 spindle.

Use a 2007 TSX front caliper .
vw corado G60 Disk brake.

All you need to do is use a special center ring because vw disk hole is bigger. Also you put the right caliper on the left and the left on on the right ( im sure you get it )

why did i do that versus EX / DA knuckle ?

first DA knuckle change your suspension geometry and is heavier than civic one.
EX knuckle is super hard yo find in canada

Bently_Coop

Link to hub centric ring?

Which Pads did you use?

Matt_EH3

These look like Hawk pads to me. Not sure which ones, as they are pretty hidden in the caliper in the picture.

If you use the 9.3" knuckle with a ring like this, make sure you keep close watch on your front bearings. I have seen a few fail with this kind of setup. They are a little weaker than the bearings from the 10.3" knuckles.

Oasisqc

ask your local machinist

pad is hp+

i also added SS brake line , RF800 brake fluid and 1'' type R brake booster and master.

Brake soo good but you need to have good tire .. i run NT01


nice to see some CCQ people here

Bently_Coop

I meant which car did you order pads for? TSX, Corrado, Integra?

Oasisqc

pad is TSX pad.

center ring is custom made.

Bently_Coop

Want to have your machinist make more?

Oasisqc

actualy im a machinist heyhey . my car is stored so i cant take any mesure but i can make some this summer.
