Sport Hatch vs SI Brakes

Does the SI come with different brakes than the Sport Hatch? like Calipers, Rotors, brake lines?

Yes. https://www.27won.com/blog/the-brake-breakdown

I question that information. As far as I know, Si front calipers and rotors bolt up to the Sport knuckles no problem. Almost bought a pair of Si calipers and rotors from a fellow member.

I'd tend to trust a company that had both cars side by side and tried to swap them more than someone's opinion. If it were something easy to do there would be a lot of ppl doing it.

I sold my Si brakes to a hatchback owner that had no trouble with them. Not sure what 27Won’s complaint was.

“Easy” isnt the only factor. It’s also not the best bang or the best bling for the buck. It may not fit into some people’s budgets, or some people prefer the bling of a BBK to throw their money at. Si brakes are a future upgrade for me, but the opportunity came at a time I was in the middle of selling/buying a home.

Look at the CTR rear swaybar. Definitely an easy upgrade. And cheap. At one point it seemed like everyone was buying them up and installing them. Guilty. Then Honda jacked the price. Still was an easy mod, but now it cost as much as an aftermarket bar. Not as much people doing it.

Good to know it works, I'd rather use those for tracking than having to buy a BBK and either swapping back to smaller every winter or selling my 16" winters for 17" ones. Plus, smaller discs means less un sprung and rotating weight. Is there a 2 piece rotor yet for the SI? Might help those brakes even more. I'm actually surprised AP racing isn't making anything for us poor people who can't afford/want a CTr.

is it confirmed the si calipers, rotors, and pads will fit on hatchback and non si sedans? will si caliper bracket also need to be installed?

Just installed oem si calipers on my ‘17 hatchback lx. I only had to trim the dust shield a small amount close to where the caliper bracket bolts up, otherwise it’s a bolt on affair. I am running ilx aspec rims that fit over the slightly larger brakes, not sure about the stock lx wheels, I no longer have them to check.

The lx dust shields are a little smaller in diameter than the new rotors leaving a small amount of rotor exposed. I used my stock lx brake lines as well, it’s a little tight but seems to be ok.

I just installed the Si front calipers on my Sport hatch this weekend. Luckily, the calipers came with the Si brake lines. I initially installed the Sport brake line but compared side by side with the Si brake line, the Si brake line is bent correctly and doesn’t stretch the flexible part of the line like Sport line does.

I’m not saying it’s a “must replace”, but something to consider if the Sport brake lines start showing wear. Up next for me, Si rear rotors. I already have the rotors and calipers bracket. I’m just trying to decide if I want to switch to the Si rear rotor splash shields or just leave them off completely.

Would you mind posting pics of the brake line comparison? I’m planning to do this brake upgrade as well.

Ok kinda tough cause it’s on the car. But pretend this is the picture of the caliper. The first pic is the bend on the Si line. The second is the bend on the Sport hatch brake line. After that bend, the rest of the line is the same. Same length, bracket, etc. so you can see how the slight bend on the Si benefits the flexible part, but the Sport kinda bends it away.

How much improvement after change guys?

Honestly, for a commuter car, I really can’t tell the difference yet (it’s only been one day, and it’s mostly been freeway). I never had an issue with the Sport hatch brakes not being sufficient. I’m sure there is a measurable difference, just not a really obvious difference. I like having bigger brakes with replacement wear items available at your local Honda dealer.

Is it worth the money? I would say not for brand new, msrp price. I think you can get better performing aftermarket kits for a little bit more. But for a used set at a fairly good price, I thought I’d try it.

Disclaimer, don’t get in the habit of purchasing used brake or safety parts. Do so at your own risk.
