I have a ‘17 civic si coupe and I’m wanting to redo my seats. Don’t get me wrong; I love the “si” logo. It’s a must. But I’m not a fan of the red. I’m wanting to change the red threading and logo color to purple. Purple stitch and purple logo. Does anyone know a site or somewhere that can make...

Can't find much on the topic, so I'll post a thread. What are the most "worth it" or "best bang for your buck" chassis bracing parts? Thinking about ordering from Ultra Racing for their November sale, but open to other suggestions. Already have the strut tower bar and sway bars Check me out on...

Hey guys! A few months back I picked myself up a 2020 Si Coupe! Absolutely in love with it, thanks to everybody on my previous posts helping me decide! I’ve done some minor aesthetic upgrades to my car so far, but seek some suggestions when it comes to the performance mods for the car! I’ve...

I’ve purchased an ‘17 Si coupe trunk lid to replace my EX-T trunk lid without a wing. Can anyone who’s done this tell me what the process is like? Is there anything special to do to make sure my smart entry to the trunk still works? Thanks so much for any answers.

I’m looking at buying an Si trunk lid from a ‘17 or ‘18 since it has a spoiler and putting it on my ‘16 EX-T coupe instead. Are they interchangeable like I’m thinking they are? I’m looking to do the whole trunk lid because my trunk lid somehow got a couple dents on top and it’s just not worth...

Sold my 2019 Si Coupe a few months ago. I just want this gone. I live in MA. Local pick up preferred.

I have a question, I have the TSP stage 1 on Ktuner. If I am under WOT and want a little more boost, does it hurt the car to hit the sport button while in WOT?

Hey, gang! So, here’s my tiny, nitpicking, issue with which I need help: One of the things I love most about new cars is how quiet they are! My Si is totally quiet except 1 thing: my passenger-side door makes a tiny ‘pop’ sound (as if some panel is momentarily unsticking its adhesive or...

Hey everyone! We are new to this forum but not to making CivicX product, so I wanted to put ourselves out there and see if anyone is interested in REAL aerodynamic upgrades for this platform. We make product for the Type R, Si coupe/sedan, hatchbacks and even the non-Si coupe - our stuff shows...

Hey All, Just looking to get some ideas on where to buy touch-up paint since my rallye red honda has a few minor scratches. I looked at Hondaparts website but they charge over $20 for shipping.

I'm just curious on why people are changing their shift knob? I'm more than happy with the stock one, looks great, easy to handle and just goes with the vehicle. If I had a Civic sport I would consider changing it but other than that I think Honda did a good job with the Si's.

I had my wiring harness for the active damper system replaced by the dealer, but I don't notice the change in sport mode anymore (steering feels the same and boost is not higher than normal mode). The dash shows sport mode is activated. Does anyone know how to reset or re calibrate sport mode?

Hey guys, ever since I got my new 2018 Si Coupe (Canadian version) last year I have been having the subwoofer rattle issues as I'm sure you all heard of. I cannot find anything on how to fix this since there aren't many Canadian Si users on here with the same problem. It seems to have gotten...

I got new Civic Si a couple of weeks ago, but doesn't feel as fast anymore... I still have a ton of fun driving it! During my first test drive I fell in love with the car and I was amazed with the speed and feeling you get driving it. But now after driving it for a couple of weeks, I don't get...

Hello! So I recently bought a Honda Civic Si Coupe (2018) and I am wanting to add some simple mods The challenge is that I am fairly new and trying to learn. I know that I want to get the Ktuner (is this better than hondata or just opinion) What exhaust would y'all recommend? Also which...
