  4. Standard BC coilovers lowest ride height

    I have a brand new set of the standard BC BR coilovers waiting to be installed with the intention of going a little lower than my D2 lowering springs.

    Can someone with an SI and the Cipher or any Harness Bar take a photo of the harness going over the seat? Curious to see how wide apart the belts look.
  6. Back for more

    I have been away from the tuner scene a long, long time. Many things have changed and like Garth Algar said "we fear change". I do anyway, a little. It's overwhelming to dive in to all the new companies, developers, race enthusiast inspired/developed products...its a lot to catch up on. However...

Not finding enough decent videos of aftermarket systems and want to put the call out there, if you have an aftermarket exhaust, would you mind posting a video (or audio) clip of cold start/warm start/revs/drive-by/in-cabin-noise/etc...
  8. Swap Back To Stock Intake?

    I’m bringing my 18 si sedan in for its first scheduled maintenance and to get the condenser looked at per the warranty letter. I have a cobra cai on it right now. Should I swap back to stock before going in? Anyone have any experience with the dealer and what happens if I don’t swap back to...

  12. Emission system problem and other fail code

    Hi Guys, Yesterday, after I filled my car and drove it for 50 to 60 miles I got all kinds of warning lights like emission system problem.

  13. Si widebody Kit, Seibon

    Was wondering if anybody had had the pleasure of installing, owning or seeing this kit in person, I really love the true to form likeness as well as real vents. Im getting a Civic Si soon, and if it looks good rather then performance mods this time, I may go full cosmetic and keep it mostly...
  14. Coils vs Bags for 19 si

    Hey guys, I just got a 2019 SI sedan last month and am trying to figure out whether to go coils or bags, and figure out which brand for each one is the best.

  15. Type R OEM exhaust on SI Sedan

    Hey guys, I can get my hands on a slightly used CTR OEM exhaust, but wasn't sure if it will fit. I know we can make anything fit with enough custom work but how much work will it really take? I hate the HDMI look and now that I have a friend who's letting go of his CTR exhaust (in favor of the...
  16. A/C fan speed trick

    So I was playing around with A/C today and notice this. When you turn the control knob on the driver side with Auto Off, it actually adjust the fans' speed! Now I dont have to press climate and wait 5 sec before I can change the setting, on a touch screen, while driving.

  20. Si Coupe Spoiler on Si Sedan???

    So I'm seriously considering buying an 18 Si, but I'm torn between the coupe and sedan. The sedan would fit my day-to-day needs a lot better than the coupe, but I love the looks of the coupe, including the spoiler. So I was wondering if there's a way to have the best of both worlds and install...
