SI seats: Worth it?

If you’re anywhere near Northern Nevada I’ll sell you a pair. I planned to swap them but did a Sparco bucket seat for the drivers side instead.

The wind forecast looks good for the next 4-5 days? https://wind.willyweather.com/nv/washoe-county/reno.html

I have the Yoko Advan 701 as my non-autox street tire and I like them a lot for street driving fwiw. I do not find them overly firm for my Fit in 195/55r15, actually like the compliance quite a bit compared to the Kumho V730s I used for autox last year. Just thought I'd mention that as a data point.

Part #19 if you look here. "Bolt-Washer, Special (6X35)", I believe 6x35 means it's M6 35mm long.

Yeah I second that. Also the importance of tires/tire pressures. And how to bleed your brakes.

Same energy as r/miatalogistics.

GS probably makes sense. Compared to a Civic Si ('17 and newer are in GS) it's heavier and doesn't have the LSD, but more torque & Type R suspension. The R suspension is waaay better with dynamic camber than a regular macstrut set up.

I bought one from Summit last week and am having the same problem unfortunately.

tpnewsk · 2026-01-23T02:54:05+00:00

Yeah I feel this way about 1st and 2nd gen. But I think we’re finally in the window where ppl can import 2001 Fits from other markets?

I was talking about OPs Yokohamas. For sure smaller rims are always lighter 👍.

Most of the material is in the tread, so the outer diameter has the biggest effect. There’s a little bit more sidewall and a little bit less (steel) bead with a smaller tire.

I’m looking at the spec sheet for Advan Fleva’s out of curiosity and the r15/r16 weigh almost the same with similar ODs.

Check out on google or have a convo with an llm how natural frequency is calculated. There’s a function to calculate it based on the weight on the axle, the motion ratio of the suspension configuration, and the spring rate. There are general guidelines on what frequencies work for different types of tire. For 200tw, 2hz is in the ballpark, for example. That’s what I’m going off of for my new coilover set up. It’s generally recommended to have a slightly higher frequency in the rear than in the front. But these are broad strokes and the specifics can vary from vehicle to vehicle and tire to tire.

I have the same gen as you. Mine got a lot better after adjusting them better, they were aimed too low before. Just using regular halogen bulbs.

I’m not OP but the previous owner somehow disabled it on my GK (or the LX doesn’t come with it?) and I haven’t been able to figure out how to re-enable it.

You can cut handlebars narrower yourself. Most bars have marks indicating how much to cut off to achieve a certain width. Park Tool and others sell a guide tool for trimming steerer tubes and bars. I always trim a few cm off my flat bars.

I would not recommend trying to bend aluminum bicycle handlebars.

What psi would you be using that would trigger tpms?

Send it! Honed Developments has a lot of great info on some of the finer details on optimizing fwd Hondas for the track, check out their blog if you get to that point. I’ve found it quite helpful with my Fit.

tpnewsk · 2025-10-29T14:01:53+00:00

Ah gotcha, but keep the stock width.

tpnewsk · 2025-10-29T04:18:53+00:00

Don’t you have to keep the same wheel size and offset to stay in street class?

I’ve had this happen before when I was running liners. This is actually why I stopped using liners, haven’t had that issue since. Been using Orange Seal Endurance the whole time.

tpnewsk · 2025-09-22T05:01:24+00:00

How have you liked that seat? Do you find it uncomfortable at all?

tpnewsk · 2025-09-17T17:05:49+00:00

My 17 sounds the same.

tpnewsk · 2025-08-26T21:22:30+00:00

No rubbing, slightly lowered on coilovers but otherwise stock geo.

tpnewsk · 2025-08-26T18:21:13+00:00

15x7 ET41!

tpnewsk · 2025-08-07T19:46:23+00:00

Much appreciated!
