I like to gather all the information about the stock and diy BBK into 1 thread.
I'll start with as much information about the stock honda brake system that i can find.
Feel free to add any information that you found.I will add more information when i have time .

Stock Brake rotor size:
2016-2020 Honda Civic hatch/sedan/coupe 282mm x23mm front , 260mmx9mm Rear.
2017-2020 Honda Civic SI Sedan/coupe 312mmx25mm front , 282mmx10mm Rear.
2017-2020 Honda Civic Type R 350mmx32mm front , 304mmx11mm Rear.
2017-2020 EDM Honda Civic Sedan/Hatch 293mmx25mm front , 282mmx9mm rear.

Brake master cylinder size:
2017-2020 Honda Civic SI Sedan/coupe : 7/8"
2016-2020 Honda Civic Hatch/sedan/coupe : 7/8"
2017-2020 Honda Civic Type R : 15/16"
2017-2020 EDM Honda Civic Sedan/Hatch: 7/8"

Brake Booster size :
2017-2020 Honda Civic SI Sedan/coupe : ?
2016-2020 Honda Civic Hatch/sedan/coupe : ?
2017-2020 Honda Civic Type R : ?
2017-2020 EDM Honda Civic Sedan/Hatch: ?

Brake caliper size :
2017-2020 Honda Civic SI Sedan/coupe : Front caliper = Nissin 57mm single piston , Rear caliper ATE 38mm.
2016-2020 Honda Civic Hatch/sedan/coupe : Front caliper =Akebono 57mm single piston , Rear caliper ATE 38mm.
2017-2020 Honda Civic Type R : Front caliper Brembo 4 piston 40mm , rear caliper ATE 38mm
2017-2020 EDM Honda Civic Sedan/Hatch: Front Caliper ATE 57mm single piston ,Rear caliper ATE 38mm

Note 1 : Front caliper Bolt spacing on all calipers (including type R) is 140mm Center-Center .Which is also used on most 1992-2015 civics.

Note 2 :Civic SI's that use the Acura TL-S brembo caliper and TL-S rotors have a brake bias that is very close to stock. Allthough the only upgrade made here is the caliper .

Note 3 : EP3/FN2 BBK have the same fitment as 10th gen civics,so these kits can be used on 10thgen civic as well.


Big brake calipers

- '05 - '12 Acura RL : 4 piston Advics 2 piece caliper with 43/43mm pistons.OEM rotor is 319mmx28mm ,total height 50mm.
Will need adaptors (fastbrakes) to mount onto the hub and is mostly used with 350z (brembo) rotors 324mmx30mm. Radial mounted


- '04 - '08 Acura TL-S : 4 piston brembo 2 piece caliper with 38/43mm pistons.OEM rotor is 310mmx25mm,total height 45.4mm.
Uses M14 bolts and will require you to drill out the hub holes to 14mm.OR use thread inserts into the caliper .( Big-Sert, Time Sert)

- '10 - '16 Hyundai Genesis Coupe : 4 piston Brembo Monoblock caliper with 42/42mm pistons.Oem rotor is 340mmx28mm,total height 56.7mm.
Mostly used with Nissan Rogue with 3rd row seats 320x28mm rotors.

- '04 - '07 Cadillac CTS-V : 4 piston brembo 2 piece caliper with 40/44mm pistons.Oem Rotor is 355mm x 32mm ,total height 50mm.


- '00 - '06 Lexus LS430 : 4 piston advics Monoblock caliper with 43/43mm pistons.Oem rotor is 315mmx30mm ,total height 50.3mm.
These calipers are very similar as the Acura RL calipers ,except these are a monoblock and are cheaper .Radial mounted

- '06 -... Lexus LS460 (non touring): 4 piston Advics monoblock calipers with 43/43mm pistons.
Oem rotor is 335mm x 30mm ,total height 60mm.The LS460 calipers are not radial mounted like the LS430 and are much bigger .

- '06 -... Lexus LS460 Touring: 4 piston advics monoblock caliper with 43/43mm pistons.
Oem rotor is 357mmx34mm,total height 60mm.Same as above but even larger.


-'01 - '06 Honda integra Type-r DC5: 4piston Brembo 2 piece caliper with 36/40mm pistons.Oem rotor is 300mm x 25mm ,total height 57mm.These bolt straight onto the 10th gen hub and works with 300x25mm S2000 rotors.


- '14 - ... Tesla model S : 4piston Brembo 2 piece caliper with 40/44mm pistons.Oem rotor is 355mm x 32mm,total height 70mm.These calipers are almost the same ones as the Caddilac CTS-V calipers .Only difference is these are spaced further out for the different rotor .Center to center bolt spacing is the same as CTS-V and will be a straight fit.


- '17-'20 Honda Civic type R FK8 : 4 piston brembo monoblock calipers with 40/40mm pistons.
Oem rotor is 350mm x 32mm, total height is 55mm.These can be fitted but need some work .Ballade sports are offering a modified version of these to mount onto the s2000.


- '99- '04 Porsche boxster 3.2 Type S : 4 piston brembo Monoblock Caliper with 36/40mm pistons.Oem rotor is 318mm x 28mm,total height 67.2mm. Radial mounted
The Honed Developments DC5/EP3/FN2 brake mounting kit seems to also fit onto the 10thgen civics ,since ep3 BBK have the same fitment as 10thgen civic.They use the Nissan Murano 320 x28 mm brake discs along with The Porsche calipers.Honed brake mounting kit


- '06 - '12 Renault Megane/clio RS : 4piston brembo monoblock calipers with 40/40mm pistons.
Oem rotor is 312mm x28mm,total height 63mm.These are used on several 10th gens in europe with a adaptor from Freakyparts uk or K-System.pro These calipers have very good wheel clearance and will fit most wheels.Mostly due to the fact these are radial mounted.

#note : Radial mounted calipers will almost always give a better wheel clearance due to the fact they are mounted more towards the back .

A lot of brake information what i have found ,i found on these websites:
- Centric parts Centric
- Brembo parts Brembo (where you can even search for rotor size)
- Racingbrake racingbrake (where you can find a lot of big caliper piston sizes and on which model they are used)

- Race technologies Racetechnologies A great brake pad comparison between the most used brake pads. Brembo HP2000 come on most stock equiped 4piston brembo calipers .A great street/race alternative is the RT TS20 (race technologies) and Pagid 4-2 (Blue).


If anyone Wants to replace the rear caliper bushings and pins.I ordered them for a fraction of the oem honda price from ATE .These are exactly the same as oem.I can recommend installing the Wunderladen Racing bronze bushings instead of oem to reduce tapered wear and overal better brake wear.

The center to center bolt distance from the calipers is the same and it's also a M12 bolt so yes that bolts on.I however didn't found any information about what Rotor you need to use with it.

Just noticed this a few days ago Civic SI's with the Acura TL-S caliper and TL-S rotor have a brake bias that is almost the same as stock.

Civic Si = 57mm brake pistons = 2551mm²
Acura TL-S = 38/43mm =1134+1452= 2586mm²

2551mm² => 2586mm² = +1.4%

Civic Si Brake Rotor = 312mm
Acura TL-S brake rotor = 310mm
312=>310 = -0.65%
Total balance = +1.4 -0.65 =
+0.75% more front brake bias which is neglectable.
If you could increase the cooling capacity of the rotor (for ex. go to a 28mm disc)
Then this would be a perfect setup for the SI.

For people interested in a rear BBK and front for that matter, I’m working directly with Rage Performance Technik to create a kit for the FK7 as no one and I mean no one makes one utilizing the OEM rear caliper. I’ve seen it for the FK8 but not FK7. They make rear kits for the Si and FK8 as well as 2piece front rotors for the FK8 with the stock calipers.

The kit I’m going with will bring the rear rotor to 320mm x 10mm w/floating two piece rotors. I also have the RL BBK up front and had them make a floating two piece rotor for that as well. Anyone who is interested, and I mean seriously interested in these options DM me so I can get a head count and then I can figure out cost. With the new civic out I imagine more people will track the old one now particularly the hatchback. I’ve been looking for a rear BBK solution for a while and the front 350z performance rotor options out there aren’t thet great.

We are currently perfecting the rear bracket as the OEM specs for the US hatchback are different to the Si. In Asia they have 282mm rear rotors (same as US spec Si). Here we have go kart 260mm ? so their brackets needed modification. I attached a picture of the front and rear rotors and the difference between our stock rears and the 320mm. Most of the other civics use the same 260mm rear rotor including sedan and coupe (non si’s) and if anyone is curious these things are light! Especially the fronts. Also virtually any color hat is available. They also have their own kits for the front with 330mm and 350mm with 4 and 6 pot calipers if that’s of any interest for people, see photos

This might be a dumb question, but I have a 2020 sedan Sport and I kinda want to get the SI brakes for the front at least. The calipers/brackets/rotors should all bolt right up, correct?

My main motive for this is that I live near Crestline, CA, about 5,000ft up, and want to help prevent my rotors from warping when I'm having fun going down the mountain. I'll admit, they are warped a little now, feel it when I'm on the brakes hard, don't feel it during regular driving. I bought the car last year with 6 miles on it, and I already have 42,500 miles on it, so I do drive a lot.

If it's a straight forward swap, I'm probably going to order everything from Rock Auto so everything is new, but still cheap.

185353156168466120

That code is good for RA until November 21st, if anyone needs it.

They should bolt up just fine.The only thing that would not fit/line up is the dust shield of the rotors.They are much bigger on the si.You could swap those over as wel but AFAIK it requires you to remove the wheel hub/bearing.You could also just run it as is.

It’s available but no group buys/discounts. I believe it’s listed for 850 on their Facebook

The SI upgrade is doable too. Also something to consider is the accord rear brakes. Cuz they are also 280mm but you can snag the rear caliper assembly on eBay for much cheaper and it’ll have the correct C bracket thet you need. I know this cause I have them myself.

Ooo wait what! I’m looking for the most cost effective way to upsize the rears

Yes so the accord rear bracket is for the 282mm rotor. On the bracket you will see “282 stamped. Ours is 260. So like I said about having rage make me a bracket for theUS spec hatch, they initially sent me the bracket for the SI BBK which had the 282mm and it did not fit. Then I remembered I had the spares from the accord thet I bought awhile ago and presto it worked. So logically if I were running the accord or Si rear rotor from stock it would fit. The caliper assembly itself is the same across the line. At preset my rear brakes are from an accord with the BBK from rage that was designed for the Si spec. They also now have the spec for the hatchback thanks to my input.

There’s a thread here about swapping to the Si stock rears. You re use the caliper but need the rotor, bracket and dust shield. I think that is the cheapest way to get the 280 size rears. I see that Rage has up to 410 (bigger than my 27won fronts so that would be totally dumb)
