    2018 Civic Type R Championship White 114k miles $26,500

    By sackofcheese

    Selling my Civic Type R. I purchased the car in May of 2024 with 65k miles. Since then, it has been primarily my daily driver, and family hauler. I used to have a 150 mile a day commute, so a majority of my ownership mileage was interstate cruising. Part of what makes these so great is you can load the whole family up for a cross-country road trip, then swap tires and go crush a back road, track day, or an Autocross. I used it for handful of local Autocross events in 2025 and 1 rainy track... 2018 Civic Type R Championship White 114k miles $26,500

    Lever For Passenger Seat Loose

    By xichigox123

    Hi all, Pretty noob here. I don't know what to call it, but it's that metal bar/lever you pull up to slide the seat forward and back. It is so loose that it comes off sometimes. I do see that the clip doesn't snap on like the driver's side. Any tips to fix this? I'm thinking I need to remove the seat and adjust some stuff. If I need to, what kind of tools should I get? Sorry the car's kind of dirty.

    Hey everyone. I’ve tried using white lithium grease all over my shifter in so many different places and I can’t resolve this squeak. It’s driving me crazy. Any ideas or anyone else experience this with the full acuity set-up? Your browser is not able to display this video.

    By KeiranKiller

    Installed 27won CAI race MAF and 27won TIP and my car has been running rich with ltft going as high as -25% generally sitting at -21% it’s triggering code p0172.

    2021 Civic Sport 2.0 NA (K20c2) Function Werk Sport Exhaust Review

    By skullandcross

    This is a review for the Function Werk Sport Exhaust for the 10th gen Civic 2.0 NA (K20c2). It's a 2.5 inch exhaust (OEM is 2 inch). Relevant mods are a RV6 catted downpipe, PRL HVI, and Phearable Stage 2 tune. Note, I am using the factory front pipe. Noise: It's louder than the stock exhaust, no surprises there but more on the quieter side of aftermarket exhausts. Which is what I wanted as this is my daily commuter. There is no drone on the highway and the exhaust note inside the cabin is... 2021 Civic Sport 2.0 NA (K20c2) Function Werk Sport Exhaust Review

    Winter wheels and tires set - $100 OBO - Philadelphia

    By Camerabuyer555

    Well, my TypeR was stolen and is now totalled out. Which sucks. I don't bring it up as a sob story or a sales tactic, just that as I find more stuff in my basement related to the car I'll try and add it to the post. First up - a set of winter wheels and tires. They've been stored in a temperature-stable space away from sunlight, in sealed heavy-gage plastic bags inside of canvas wheel bags. They were stacked with thick cardboard disks between them to guarantee no moisture was trapped in... Winter wheels and tires set - $100 OBO - Philadelphia

    Hey, Ive got ideas and need help turning them into physical pieces. Anyone in here build prototypes or have a resource for prototyping? 3d printing would probably work initially. Someone in or close to washington state would be ideal to be able to collaborate in person.

    2020 Honda Headunit Software Update - Overcoming The Impossible

    By Check Out Bofa

    Car is a 2020 civic 1.5L with a 7" screen. According to Google, there should be a software update tile in the settings menu. There is not. There is also no option to export settings via USB in order to download an update to a USB drive. It seems to be software locked. Here are the versions I thought may be worth posting: Diagnostic Menu Info Bootloader: 1.12_20190613021043 Kernel version: 3.1.10+ Build #: 1.F1A5 15 Hardware version: 01.111 "Version... 2020 Honda Headunit Software Update - Overcoming The Impossible

    Strut mount or steering rack?

    By MikePA717

    Hello! I've been dealing with this for years. I'll try to be quick and to the point. It's a 2019 LX with 111,000 miles. I live in Mid-Atlantic USA. All four seasons here. Since 2023, when I bought my car used, I've had an issue during summer months. It had binding or sticking steering in left turns. In winter it goes away and then comes back next summer. This year, it got so bad I was afraid to drive it and took it an independent shop. Of course we had cool weather the day it went in and... Strut mount or steering rack?

    Weird Issue?

    By 2018civiclx

    Hey everyone, my sister has a 2020 Civic Sport Sedan and since she got it (used last November) it acts weird sometimes. It’s a great car but on hot days when starting the car it’ll act weird or stall and then weakly start after. Occasionally it happens pretty often but while driving a couple messages pop up saying “collision mitigation system error” and “lkas system error”. We’ve taken it back to Honda but they’ve said it has no issues and the battery is still new. Just confused but this... Weird Issue?

    W2 turbo oil leaking

    By mikepergov

    My W2 BB turbo started leaking oil from the center section; it seems to be coming from the CHRA area. I’ve already replaced the oil return line gasket and checked the feed line banjo bolt. What it could be the problem? The turbo feels like it's working well when the boost kicks in, and I haven't seen any smoke from the exhaust. Your browser is not able to display this video.

    Club-Version x M|M|E Shim-Adjusted Rear Toe Arms

    By Club Version

    Hi all, just dropping in from the CIVICXI Forums! I’m excited to announce that I’m helping develop the first shim-adjustable rear toe arms for the FL5, FK8, and DE5 chassis. TCR race cars use shim-adjusted arms, and I’ve long wanted a similar solution for our street cars. After more than 30 track days in my FL5, testing each modification individually, I’ve reached the point where the factory arms and their rubber bushings were limiting rear-end response during high-lateral-load corners. In... Club-Version x M|M|E Shim-Adjusted Rear Toe Arms

    2019 Civic Si Coupe Trunk Torsion Bar Delete

    By sublimewookie

    TLDR: torsion bar swap for struts for bigger subwoofer My sub died and I want to upsize its replacement. I have seen the headache that ensues with the 2019+ CANBUS system and am mentally preparing for that. In my research the torsion bars are a problem for upsizing the sub. Has anyone done a swap to struts on the coupe yet? I was hoping for advice!
