Si brake rotors

[17SIYoDood]

Is it me or how come i can't find Slotted only rotors for the 10th Si? Then everytime I think i find them. I cross reference the part number provided and it goes back to a 11.1 inch rotor for the base models... it's as if every company has rotors for days for the regular sub models or the type r NOTHING for Si's for 12.1 inch rotors. Someone please find me or point me in the direction of Si rotors that are slotted. NOT drilled and slotted or drilled. just slotted haha. I'm going nuts here looking. If you cross reference anyones part number provided its alwats for a 11.1 inch rotor

I've seen that problem with the EBC rotors listing the Si as the base specs.

R1 Concepts has separate listings for Si and other sedans. They don't list the specs but if you change from Si to the other trims you can see the part #s change. They have their E-line coated rotors and Geomet high-carbon for a bit more money.

https://www.r1concepts.com/detail_c...020+Si+Front_and_Rear+Slotted_Rotor+silver+++

You could contact them to confirm the sizes to be absolutely positive but at least the different part #s for Si are promising.

StopTech makes slotted and cryo-treated slotted rotors for the Si but only for the front axle.

StopTech slotted
Front Left - 126.40094SL
Front Right - 126.40094SR

StopTech cryo treated slotted
Front Left - 126.40094CSL
Front Right - 126.40094CSR

Si has a unique front pad shape but the rear pads are same as the other trims even though the rotors are different.

Get the Geomet carbon R1Concept rotors, no rust. I’m sure there is some rust if you live in harsher environments, but it’ll be at a slower pace. In sunny CA I have no rust at all, except obviously the occasional thin rust on the portion that the pads contact

Hey there
At Unity Performance we carry StopTech Slotted Rotors. You can find the front here: https://unity-performance.com/colle...products/stoptech-front-rotors-si-coupe-sedan
And the rear here: https://unity-performance.com/colle...s/stoptech-slotted-rear-rotors-si-coupe-sedan.
If you are looking for a great daily set up, I highly recommend getting some Hawk 5.0 Pads along with the rotors. You can find them here: https://unity-performance.com/colle...oducts/hawk-hps-5-0-front-brake-pads-civic-si

Reach out if you have any questions

@jayy_swish Any coated rotor will avoid rusting like that. R1 E-Line & Geomet and StopTech are all coated.

@Unity Performance Looks like Centric/StopTech needs to update their online catalog! Only the front application for the Si shows up in the parts search on their site. They have a catalog listing for the part #s you have for the rears but the pages for them don't specify what car they fit.

EBC brakes offer all thoses rotor for all Civic.
They have 4 models with customs drilled parturn.

Models: EBC USR series , EBC GD series , EBC BDSseries and EBC Racing .

Features:

• Dimpled and slotted
• Corrosion-resistant thermic black or Nitrotherm finis

Just make sure you bought the right size -> 12.3 front and 11.1 rear.

I just bought those EBC BSD Front SKU : BSD7741 / Rear SKU : BSD7801

@alxgravel That's good info on EBC. For some reason most of the catalog listings for EBC for the Si are wrong for the Si but Edge has correct sizes for the Si.

EBC uses different prefixes in their part #s for the different style of rotor, RK for blank coated rotors, USR for slotted, GD for slotted/dimpled, and BSD for high carbon blade slotted.

It looks like the _7741 front & _7801 rear part #s are the correct 311.8 mm front & 282 mm rear sizes for the Si.

But Edge is listing the _7801 part numbers for all 1.5T Civics, and non-Si 1.5T Civics, at least in the US, have 260 mm rear rotors. The correct EBC suffix for the non-Si 1.5T 260 mm rear rotors is _7752.

Well I never looked up for non-si 1.5t you mark a good point!

I'm having one question for pads ... I bought my front brake pads EBC yellow stuff DP41896R and now I want to make sure that the DP42301R fit on my si rear pads.Maybe @Unity Performance could help me on this I saw they added EBC pads for our car but with out the part ID ( On their site they say that the rear pads fit on all models ).

Thanks in advance

Hey Alex, DP42301R is the correct part number that we also carry. Rear pads across the platform are all the same shape, despite the rotor size difference (and hub for CTR). There are many on this forum including myself who have tried Type R pads on the Si.

In fact, I'm removing the Gen Coupe Brembo Kit off my Blue Si, will be going back to stock calipers front, and my setup will consist of:

EBC Yellow Front (DP41896R): https://unity-performance.com/products/ebc-yellow-stuff-front-brake-pads-civic-si

EBC Yellow Rear (DP42301R): https://unity-performance.com/products/ebc-yellow-stuff-rear-brake-pads-all-civic

StopTech Slotted Front Rotors: https://unity-performance.com/products/stoptech-front-rotors-si-coupe-sedan

StopTech Slotted Rear Rotors: https://unity-performance.com/products/stoptech-slotted-rear-rotors-si-coupe-sedan

Goodridge SS Braided Lines: https://unity-performance.com/products/goodridge-ss-brake-lines-honda-civic-si

Motul RBF600: https://unity-performance.com/products/motul-rbf-600-dot-4-brake-fluid

The above will be an awesome street setup with light to mild track capabilities. Above this category of pads you have to go to race pads. Once I wear down down the EBC Yellow's, I'll test either Carbotech or G-Loc with RBF660 Fluid - this will max out the Si's braking system, and then I'll return to my next BBK! Gotta test everything

Believe me, we've spent a lot of time on this topic of brakes!

 

[alxgravel]

Yea believe I you hahah ... I did my homework to and also spent a lot of time finding the right brakes for my si. I saw a lot of great reviews on EBC Brakes on the internet and I finally decided to try EBC product. I liked the style of the EBC BDS rotors and will change everything for the next summer ! Its this fun to saw alot of compagny supporting the 10th gen here and keep trying product for us. ?? big brake kits are big money lol ... and I will maybe buy downpipe and clutch before it !

 

[CodeFault005]

Dropped some R1Concepts slotted E-line, black zinc coated rotors on the rear today. OE's were all warped with hairline fractures! (C'mon Honda, you can do better than this!!)

 

[alxgravel]

Finaly bought my rotor... yesturday I couldn't past on the r1 geomet rotor set it was 30% rebate on it so I give them a chance. EBC bsd setup was like 850 cad and this set was 219.99 us in rebate. They will be pair with ebc yellow stuff pads! I PMed the service and the support guys gived the right dimension. I will kept you update on those.
