Si rear brakes on Sport hatch

[L8apex]

Is this the correct part number for the replacement rear hub bolts?

90160-TBA-A01

Correct. You’ll need 4 per side.

Awesome write up! I actually was thinking about offering this upgrade locally today but stumbled on this thanks to Humza...

Good work.

In case anyone was interested, I found the harness clip that I snipped off. 91507-SWA-003.

Thanks for doing this. I’m doing the 27won front BBK and I feel like even tho the performance gain won’t be there in the rear, this might make the appearance a little more balanced

According to the parts catalog, they are not the same part. But they have interchangeable pads. And the piston seal is the same part. Which tells me that internally, the dimensions (caliper bore and stroke maybe) are the same.

Some people have gone further into the research and it seems CTR rear calipers will also bolt up, but are a bit more expensive since they’re aluminum. https://www.civicx.com/forum/threads/type-r-rear-brakes-on-si.56337/page-2#post-918855

You can do that too, if you can find them cheap, they’ll bolt up to Sport hatch, Si, or CTR brackets, just need to get rotors that match. CTR diameter but 5x114, not 5x120.

That thread also says there’s not much to be gained from rear diameter upgrades, so again keep that in mind when you’re budgeting/prioritizing for these.

CTR rear caliper is also the same just painted red. It is not aluminum
