I know that this setup is actually quite well-known by todays enthusiasts and is a few years old at least already, but I believe it is not known enough, I had to do quite a bit of digging to come up with only one or two forums threads that ended up being helpful, so I bit the bullet and ordered all this stuff to try it out. You can do this similar setup for cheaper, or more expensive depending on what parts you buy/don't buy, this is just the setup I chose to use! You WILL NEED civic ex or Integra DA front spindles.

Went to my local junkyard on a half-off weekend and scored a complete set of DA9 Integra front spindles/knuckles/whatever for $55. I ditched the calipers to save some cash, ended up buying the rotors and caliper brackets not really knowing what i needed, and we all know those damn rotor retaining screws love to rust in (NOT getting that out with basic tools at the junkyard Lol)




Came home and ordered a set of steel braided brake lines for 88-95 civic (with rear disc because I have EM1 trailing arms rear disc conv.) for like $65~ , went to http://www.rockauto.com and ordered their Centric Integra Type R (i think I put year as 2000) front calipers (with brackets) for $30/ea + $15ea core charge, hopped back on eBay and ordered a pair of 2007 Mini Cooper (non S, just base model 280mm) front rotors drilled and slotted for $80. EVERYONE else I've seen run this setup has gone with rockauto's centric premium blank rotors, I chose to run drill/slotted because I don't like the feel from blanks, they always warp and vibrate IMO.... Also ordered Hawk HP+ front Integra Type R pads for $100, a brake master cylinder for a 88-91 Prelude (15/16 bore) for $30, and some high temp WilWood 570 brake fluid for another $30~.


Comparison of the 11in Mini Cooper rotor vs 10.3 Integra and 9.4 DX rotors



DA9 spindle and DX spindle, you can see the difference in sizes





New DA spindle on, rotor slides right on



Comparison of my old 13/16 MC and Prelude 15/16



Centric ITR caliper



Part # for calipers, I beleive other side was a 49 at the end



ITR caliper bracket bolted on



This is where it got good. Unlike when you run re-drilled Prelude VTEC rotors where you need to run a spacer on the backside of the rotors to get the rotor centered in the bracket, the Cooper rotors center right up perfectly.







Comparison shot of the ITR caliper vs DX caliper. Woah.. Lol



Clearance over my 949's and Buddyclub street wheels



Barely clear my 949s though



Starting to bench-bleed the MC




All in all I spent approx $365 on a DIY BBK, Like I said you can end up spending less/more than me depending on which parts you decided to use, but the basics are here! ex/si/integra spindles with 280mm (11in) 2007 Mini Cooper rotors, and Integra TypeR calipers & brackets. You'll notice that the Mini rotors holes for the wheel studs are bigger than the Hondas, but it doesn't matter, the center bore diameter (which is the same as the Honda) is the only thing that means anything for this.






Comparison of the DX pads versus ITR sized pads... Holy ****.



A Shot of the 88-91 Prelude MC installed. (Yes it requires a little tweaking of the front line because the original 88-91 Civic MC port is at an upward angle) But it was not difficult, I had the MC bolted up and lines attached in a matter of minutes.





Hawk HP+ pads installed, I read originally that the pads would overhang just a hair on the rotors, but they seemed to line up pretty damn flush at the ends.

Awesome! This upgrade is (obviously) a direct bolt on for Integras and is pretty common on team-integra. Another option you have is to used rsx type s rear calipers for the rear, just flip the left and right calipers. It can be more difficult to bleed but they are cheaper to find.

90ED6LSV

Yeah i've read something about that before, which rotors do you use for that setup in the rear?

m4xwellmurd3r

I believe you use 2002-2005 civic si rear discs

^ correct. EP3 rotors with integra type r or rsx-s pads

Nice write up!

I hear there is a big brake adapter for the rear aswell to get an 11" back there aswell. Fastbrakes I believe? And then which rotors do you run? I believe they just push out the stock caliper which is great and allows you to run stock ebrake cables.

Has anyone had any luck with bigger brakes on the back of the EF?

90ED6LSV

I'm not exactly sure what upgrading the rear brakes might do, from my little track experience the rear brakes hardly get used at all. My rear rotors have two track days on them and they still have the machining cross-hatching.... Wheels had barely any dust whereas the front wheels turned black from silver, and the rotors/pads look like they'd seen better days Lol. FWD's on the track really overuse the front wheels, they do practically ALL the braking.

F22Master

Seriously looking into this... If I can find some EX knuckles for cheap i'll probably do this.

m4xwellmurd3r

Yeah im thinking stock da rear rotors are good enough and do mini cooper rotors up front. Ive noticed the same thing on my car. The rear pads still look new after a year and the fronts have obvious wear in comparison

KoRn_vIRuZ

Very well written DIY, and much appreciated.

Given that the stud holes are a little too large (16.25 vs the correct 12.8 mm) on the front rotors I am a little concerned the rotor might rotate slightly on its axis when the brakes are applied. Did you notice anything that may suggest that when using the brakes?

Also, were you able to fit the OEM rotor retaining screw?

Thanks!

90ED6LSV

Negative on the OEM rotor retaining screw, the Mini rotors do not have a hole in the correct location for it. I think with the wheels torqued on, that would be enough pressure to prevent that from happening, there's plenty of guys running this setup for both street & track.


BTW - I got to take the car for a spin today, brakes are downright amazing. I should have done this years ago... Daily driving the braes feel nice and firm, but step into them a bit and holy hell. I haven't really slammed the pedal hard yet, I seem to have an issue with the front end feeling weird, I think I installed the Innovative crossmember bushings I got wrong, caster seems a bit funked up. Hopefully have some more time tomorrow to check it out and go for another test drive. Also have a little squeak until I apply the brakes, not sure if it's just rubbing off the coating on the rotors or what just yet.

So, does the rotor still locate on the hubs center ring? Or only by the lug studs?

Im asking because I already have brand new wheel hubs(and bearings, for the DX knuckles I have), but they are non-EX. New EX hubs are pretty much non-existent. If these rotors would work on the smaller hubs, then I could just get some EX knuckles and use my new hubs and bearings!

EDIT: Found my answer here: http://www.performanceforum.com/wesv...hubs/hubs.html

Seems I could use my non-EX hubs on EX knuckles, and still do the BBK. And If I was really concerned, I could make the spacer/collar shown. Awesome!!!

KoRn_vIRuZ

Thanks for the reply. I'm inclined to give these Mini rotors a try, seems better than running Prelude rotors with spacers plus the hassle of extended studs. I might have a shop drill holes for the retaining screws though, just for peace of mind.

Not ef related but just wanted to get some good info on what are good brake lines for a 2000 civic cx Im about to install 11.1 type r brakes and rear si brake. I know to get stainless just wanted to know what type brand and what year make for car.

KoRn_vIRuZ

Stock Honda ones really. Braided hoses are more prone to failure and not worth the risk in a street or even fun track day car IMO.

twomspeedek

what type of brake lines would i have to order if i am using type r front calipers and brakes. and si rear and brakes.meaning the year and make and model of car..

So if I am using type r front brakes with mini coopet rotors and si rear brakes. What yeat make and model of brake lines to I get. Also what type a brake fluid should I get dot3 or dot4. Thank guys

90ED6LSV

Yes the rotors slip right on the wheel hub center ring, the Mini's have the same exact bore!

Note - I did test the Mini rotor on my DX spindle and the center bore was larger than the wheel hubs on the DX spindles.

90ED6LSV

You might be able to just buy brake lines for any 94-01 Integra / 92-00 Civic (REAR DISC), I believe the brake lines I bought for my car were rated for 92-95 Civic with rear disc. I think the only differences between lines is going to be lengths, I believe all the banjo fittings should be the same? As for brand, Goodridge makes some nice stainless braided lines.

twomspeedek

Thanks for the info once i complete my civic i will upload pictures

twomspeedek

how are you liking the brake set up i am about to install this on my civic im afraid my 15inch gt3 rotas will not fit now....i was also told this set up does not hold good because of the caliper being too big on the bolt side

stinkbox

Does this setup apply to DC/EG/EK as well???

Fink29

Yes it does. You just need the DC or Ex 10.3 spindles.

stinkbox

Sweet! Wonder if they fit over most OE honda wheels like the stock EM1's or GSr fat fives ect. I doubt they clear them though.
