Dual piston calipers will be an upgrade over their single piston counterparts. Looking at the caliper shows that the mounting bolts are 14mm which means you will need to drill the holes on your knuckles to fit. The rotor is 296mm diameter and 28mm thick which is similar diameter (300mm) as the 8th, 9th Gen Si and TSX, but thicker. So the rotor will have more heat capacity than those previously mentioned rotors. I have not tried to use this combination before so I cannot comment on fitment.

just clarifying the question here, are you trying to put the rear Brembo Calipers of a Genesis on the front of your RSX? or on the rear of your RSX?

Front

It’s not a direct bolt on for the rear Genesis calipers, as the bolt hole spacing doesn’t match up to the RSX upright. You would have to get some kind of custom adapters made to get them to fit. So it can be made to fit around a variety of rotors

The rear Brembo genesis calipers bolt on with no modification to the front of my RSX . Only thing is I can’t find the right rotors . I’ve tried the Nissan rogue sv and they are too thick

Interesting, never tried to find a rotor that fits the rear Genesis calipers, I would imagine you will need smaller diameter and different offset

Thank you!!

Hey there! I just want to caution that tire size, compound and sway bar sizing will influence your spring choice, so please adjust accordingly. If you want to use my setup as a starting point you are more than welcome to. I am running 900/550 lbs/in front/rear Eibach ERS springs.

@formuladelta4929 900lbs spring rates Wow 😳 ! I thought the 'Koni Sports' can't handle more than 600 lbs.

Well, the word handle is kind of used loosely in that context. I don’t know the exact technical specs of the Koni yellow’s valving for this application, but it does not have enough damping for the shock to critically dampen the 900lb/in springs, but it still does a decent job at it. The Koni yellow race shocks would be a better fit for the front spring rate, especially for a stiffer spring, but then I would lose the lifetime warranty, it’s a trade off for sure.

@@formuladelta4929 What would be the softest front spring rate you would run on a 15 x 8 rim with 225 wide tires on those Koni shocks? 🤔🤔

The rate here would more depend on the grip of the tires you are running and how low you want to keep the car. If you are running really high grip tires then you want higher spring rate. If you are constantly driving on smooth roads, with very little bumps then you can go higher spring rate. If you are very low and have very little suspension travel left before bottoming out then go higher spring rate. Good starting point for 200TW 225 wide tires on koni yellow shocks without going too low would be 500-700lb/in front and 400-500lb/in rear. Adjust to your liking from there.

Rotor height is 56.7mm, if you bolt it on then the rotor won’t be cantered in the callipers. This parameter in conjunction with the rotor thickness and the hub mount thickness also has to place the rotor in the center of the calliper to get everything to bolt up

Its same 94-01 Acura Integra 32 mm hubs same as the 96 to 00 Honda Civic EX and I believe it's the 90s Prelude si hub 4x114.3 also the Acura ITR use a 32 mm

@@sherryhilbert7888 yes 🙌🏼 I just upgraded to the 98-01 ITR calipers and I had to use the 96 prelude v-tec rotors 11.1 with the 4 by 114.3 bolt pattern and 96 accord ex rear rotors 10.5 for 15 in wheel.It was a nightmare trying to figure out this conbo.thanks bro

@@Everydayprojects365 if you want to upgrade your rear you can add the first-gen ep-3 si you just flipped them upside down on opposite sides so the right side goes on the left side

@@sherryhilbert7888 would I use the same rotors? How much bigger are the ep3 rears?

@@Everydayprojects365 2003 ep si 10.3 in rear

Not 100% sure about the Acura RDX, but there are forum posts about a 2017 Honda Pilot that fit the Genesis Brembos with some bolt bushings because the Genesis Brembos uses 12mm bolts and the Pilot brakes are mounted with 14mm bolts. Not sure if the Pilot and RDX has any similarities in the brakes department

The RPF1s in this video is 17x9 +35, it was tight on the barrel. Might work with 18x9 and a spacer

If you are leaving the rears as drums then there’s no need to change the proportioning valve. As for the MC and booster, it is more of a personal preference, going to a bigger MC will decrease the amount of line pressure for the same pedal force input and reduce the amount of pedal travel. If you choose to use the existing MC the pedal travel will be longer with the ITR calipers. If you go to a bigger MC (7/8”, 15/16” or 1”) there will be less pedal travel. Bigger booster will give you more vacuum assist, effectively reducing the amount of pedal force you need to generate the same line pressure. Do you prefer a heavier or lighter brake pedal? Do you prefer more of less pedal travel?

@@formuladelta4929 well now I got to contemplate all those things .😂 I REALLY appreciate your response and the knowledge👍🏼👍🏼

I just made the rear disc conversion putting a 260mm rear brake disc and no difference, u might buy the prop valve 40/40 non abs and might see some difference

The limiting factor for wheel clearance is the caliper not the rotor. Reducing the size of the rotor will only increase pad overhang. It will not improve wheel clearance.

@@formuladelta4929 right., cause the caliper is the one that sticks out the most from the assembly., got you, Thanks!

I ended up going with 720 Form GTF1 17x9 +25 with a 10mm spacer. Other wheels that fit would be the Konig Hypergram or Dekagrams in the 17x9 +25 or the 17X10+18

@@formuladelta4929 awesome thank you. Very helpful 👌

Not really, other than a slight step in the pad wear. Would recommend looking at the Sentra SER rotors, which has slightly bigger inside diameter, which gets rid of the inside overhang. Someone on Instagram recommended this option as an alternative to rogue rotors.

@@formuladelta4929 awesome thanks! Any issues with noise from the brake swap? I've been reading on a forum and there were several complaints about a squealing noise.

@@FieldGenEJ That’s more about the brake pad compound selection than the caliper and rotor choice. I know for sure that the Hawk HP+ squeals a lot, by design. Also the very high performance/racing pads might squeal as well, mainly because it’s purely performance oriented and noise is not a consideration during design.

Hi Paulo, thanks for visiting the channel and subscribing, I would recommend also going to the TSX calipers with the TSX rotors. Technically speaking with some caliper bracket clearancing and used brake pads, you could probably get the TSX rotors to fit with 8th gen Si Calipers. My concern is that the caliper bracket doesnt have enough room for the increased rotor thickness of the TSX. For the cost of the calipers its not really worth this hassle.

@@formuladelta4929 thanks once more for the info! Sadly here in Brazil it is quite hard to find those calipers. Actually the Acura TSX wasnt even sold here haha. But... I know by looking the specs that some Accords have the same rotors on them, which I can order for a reasonable price. As the rotors on said Accords are the same probably the calipers are also the same, but I am sure it will be hard to find em. I think the number of these cars ever sold in Brazil is less than a month worth of sales in the US...

@@paulo..ferreira Get the rotors and see it fits your current calipers, if they fit then great! otherwise you can try getting the other calipers!

Can I run 14" wheels with this set up?

DC2R Calipers with Mini Rotors

720form GTF1 17x9 +25, sadly they are discontinued. The front fenders are totally destroyed to fit 255 tires underneath them. Might be able to make them look presentable if I had more patience when rolling/stretching/pulling them

❤

Novustech.ca they are a Canadian Company, they will have Honda fitment which is 64.1mm Center bore

not sure if your stock wheels will work, check out my other video on wheel clearances. MC and booster should work just fine, the brake pedal travel might increase a bit, but that is personal preference, so adjust MC size accordingly.

Fronts only

Yes, 8th gen Si. Cant confirm on regular 8th gen civic though

@@formuladelta4929 thanks for the info.

OEM will work just fine for the street, OEM with upgraded pads and rotors will handle spirited driving on the streets, even light track duty will be fine on the OEM DC2R brakes. This is an alternative to other BBKs on the market, whether you are modifying for the aesthetics, braking feel or the performance is up to you
