With the Hondas it seems like they don't require all that work, but I will leave it to the Hasport guys to figure it all out and document it. We will certainly find out.

The L engine uses it's own bellhousing type, but it looks like that is swapable with the 6 spd in the Civic Si. Brian @Hasport has more info than I at the moment.

Fastbrakes swapped over the Fit to the 4 pot 11.6 brakes and rear disc swap this weekend with the help of our friend from Hasport Brian Gillispie.

Is the Fit serving double duty as a rally car? That underbody is filthy!

Brian Hasty 09-19-2017 12:48 AM

All 4 struts/shocks are leaking, looks like the original ones from Honda, 142k miles on them! Replacing them with BC Racing coil overs in the next couple of weeks, along with lower control arms, Progress rear sway bar. Will be giving it an extensive underside cleaning/scrubbing prior to installing the Ultra Racing chassis braces.

In that case, go rally it before it gets a good scrubbing! :D

Nice! Go with the standard springs/rates or did you go custom with Swift springs?

I think the standard rates are 5k/6k which don't sound bad to me, but haven't tried them.

idrivemyself 10-11-2017 09:20 AM

Nice. Are you upgrading the control arm bushings and ball joints as well?

Brian Hasty 10-12-2017 10:41 AM

We should be changing the ball joints to reduce bumpsteer, but don't plan on changing the bushings to anything harder. The car isn't going to be a track car so we want to retain some civility in the ride.

Brian Hasty 10-12-2017 10:43 AM

We kept the stock spring rates that BC sends to keep it a decent ride. We can always change them later if we need higher rates.

Brian Hasty 10-30-2017 09:47 PM

Picked up a Civic Si seat to see if it will work in the Fit.

Brian Hasty 11-19-2017 11:03 AM

Here's the Ultra Racing chassis braces we will be installing on the Fit once the engine swap is completed. The Fit is going to the Hasport shop this week to be used to re-design the K series engine swap brackets, and then the L15 Turbo will be fitted and mounts fabricated.

We did notice the rear axle bushings were starting to tear so we will have to replace those at some point, probably while it's at Hasport.

GAFIT 11-19-2017 02:26 PM

Nice score on the Ultra Racing braces! I did not know those were still available. Please let us know how the fitment goes.

My understanding on the bushings for the rear beam is that there aren't any that are a true exact fit for a USDM Fit. From what I have been told, the ones linked below are the closest...


idrivemyself 11-19-2017 05:57 PM

^The UR braces don't fit 100% to our USDM models either. Many of the bolt holes are drilled to JDM/ROW model sizes.

And yes, those Febest bushings are the best of what's readily available. Custom polyurethane bushings are the only other real option.

Thanks for the info on the braces and the bushings. I'm sure I'll be modding the braces to fit, just like I had to do on my FX16.

Brian Hasty 11-20-2017 07:09 PM

Did SuperPro get the bushing sizes straightened out? I'm in need of them now.

Glad to see this thread exists. Also following this on Fastbrakes.

No, SuperPro ended up dropping interest. As you've seen, anyone with a lathe or access to a machine shop can fit the JDM/ROW bushings to our USDM models. Let me know if you need measurements and additional info on retrofitting them.

Nice build man!

Where did the rear disc parts came from?
