I don't know if this has been shown, but I figured out how to use the Mugen calipers to get an even bigger than ITR upgrade on our cars now.

The caliper is about 9lbs compared to the ITR's 13.5lbs. The rotor is the same weight as the Legend GS 11.1" rotor but is a more effecient design giving better cooling due to its heat vane design.


These calipers were painted silver (and without the stickers though.) This uses an 11.8" rotor which is hub-centric to the Integra. It was redrilled to 4x100 and the brackets have to be milled similarly to the ITR upgrade. FYI, this particular setup is for sale, clears 16s and 15" CPFs and TE-37s, and is a bolt on for 90-01 Integras (maybe 1st gen?).

 

Ok, so are you going to explain the what, where, how and why so that we can go about creating and retrofitting one of these systems ourselves? Or is this a "Hey look how cool I am and now you guys can bend over and buy it from me if you want it" post?

In other words, where's the tech?

 

those look like prelude rotors redrilled to 4X100

I'm willing to bet that they are S2k rotors and calipers.

S2K rotors would not work well as they are 40mm tall compared to 45mm for the non-ITR Integra. I am skeptical of the authenticity of the pictured rotor because they fit the center hub. The ITR uses a 70mm center hub and the non-ITR has a 64 mm. They could be 282mm Accord rotors (5x114.3 with 64mm center bore). Regardless, I will never be a fan of redrilling a 5-lug rotor to a 4-lug pattern due to the overlap.

 

What about the RSX's?

It is possible, though I doubt a 15" wheel would clear a 300mm rotor and caliper. The OP indicates an 11.1" rotr, which is 282mm. Here is where I pull rotor dimensions.

Choose the Honda catalog.

 

Sorry I had to leave, let me clarify.

Those are the Mugen calipers. Yes the S2k calipers are very similar.

They are not prelude rotors, those would be 11.1"
These are 11.8".

They are perfectly hub-centric. They are from an RSX Type-S. Most of the newer 5x114.3 hubs Honda uses have a smaller centerbore and outer hub diameter, thats why this setup cannot work on an ITR.

Redrilling rotors with an overlapped hole is 100% safe. Remember that this is a rotor-over-hub design. This means the hole in the rotor is there solely to let a lug stud through to get to the outside of the wheel. It is not load bearing hole. The pressure from the wheel is dispersed throughout the entire surface of the rotor's hat. Drilling a few more holes does not make it unsafe. If you would like to calculate the added pressure (though negligable) find the SA of the wheel you have, calculate the lost SA of the rotor's hat due to the new holes, and divide, and theres your percent increase in pressure. However these are solid cast iron which as we know can take a shitload of pressure.

This was more testing and throwing a setup, sometimes I list every spec and no one cares.

This is an 11.8" diameter RSX-S rotor professionally redrilled to 4x100 and is hub-centric. The rotor is 25mm wide. The caliper takes an S2000 pad and is pulled from the Mugen Active Gate brake upgrade kit. The bracket was milled on the back as it brushes JUST slightly on the inside. This is a great step up from the ITR setup and clears 16" wheels. Just throwing another option out for everyone.

Sorry, I did not mean to stir up any harsh words. Is there any other tech you would like? I just got done fitting this setup and was very excited so I thought I'd share.

As I stated, the 300mm rotor in this setup...this setup CAN clear 15" wheels, I have seen it.

 

Can any other caliper be used, or is the mugen the only one? Any modifications required to fit the caliper?

 

very interesting. However how much are mugen active gate calipers? Can you buy them seperately?

I have no problems with the bracket and the rotors. but Im concered about the caliper.

can you please explain why s2k calipers dont work? I dont understand the 40mm vs 45 mm tall thing. what dimension are we talking about?

The S2000 rotors are 40mm tall vs. the 45mm for the Integra. That dimension is the distance from a flat surface to the top of the rotor if the rotor is lying flat. Look at the link that I provided above for further clarification.

Are you still running 70mm center bore rotors on your 64mm hubs?

 

but couldnt you use s2k calipers on stock integra rotors? or possibly RSX rotors according to this guy?

You could use the RSX calipers. I know that the DC5R Brembo calipers will bolt right up to the DC2. The S2000 rotors have the correct rotor height, but the center bore and bolt pattern is incorrect. The real issue with the DC5R calipers is the wheel spoke clearance due to the outboard pistons.

 

The S2k calipers should go on the integra knuckle, but the integra rotors are much smaller. The stock ones are 10.3", the ITR rotors are 11.1", this is an 11.8".

You could use a redrilled RSX rotor like you did above. You'd have to machine the caliper bracket for rotor clearance.

 

It would have to be the Type-S rotor though. And yes the bracket has to be machined, but only like a millimeter or so, there is actaully clearence stock, but there is light brushing from rotor to the inside throat.

?

I'm sure this setup would cost more than piecing together a brake upgrade using prelude/accord rotors, prelude rear calipers and legend from calipers w/CRV knuckles.

The Mugen calipers, I woudl think, are several hundred.

 

Interesting.

Sorry if i'm not reading correctly, but do you have a picture pointing out where material has to be removed from the caliper?

I'm trying to understand if it is on the knuckle-bracket portion, or as you said, the rotor side, so the actual material being removed doesn't have to be precise (so i can just use an angle grinder)

 

It is in the part of the bracket where it meets the knuckle. It must be precise. This bracket I did a few weeks ago I used a mill end and took off .050 inches. Bracket mounts just fine as in the picture I posted.
