civic si

Hey Guys, So I picked up my brand new civic si hfp 2018 from the dealership two days ago first night drove fine and then last night I went to the mall and when leaving I got a warning light on the dash that said Suspension System (ads) problem. This car has only 200km on it and I have dont a...

Sorry if this questions sounds dumb but I’m new to the turbo world, I’ve built B20V, H22 and GSR with my brothers but this is different. I’m looking at the PRL Cobra Intake. I see the difference between the Race and Street, and I know it’s recommended to have a tune for the Race. What if I...

I figured I should start the Brake pad thread since I did not find any. Very few options are out for the Si even though they share the same brake calipers as the Accord Sports. When new products come out in our size, please post a link and a part number if possible. If you have upgraded your...

Part numbers. Front: HB875B.666 - Rear: HB900B.572 They have ~2,000 miles on them SOLD

I'm selling an eibach pro kit for 17-18 SI, new in sealed box. Decided i wanted to go lower and the place i bought it from said all sales final. 200$ shipped or local pickup oxnard/ventura CA area.

Hi my first post yay! Well I got an si (my first manual car) about two months ago and even though I really like the stock oem shift knob, I want to replace it with a weighted shift knob but I had couple questions before I commit to it... I’ll try to make your eyes easier by listing them 1.Does...

Hello Folks, So I got my brand spankin' new Civic SI '18 yesterday... and today .. like an idiot.. I swiped it by a sidewalk pretty hard. Most of the damage is to the front bumper on the right side and not just scratches. Looking for advice on what to do? Should I buy a bumper and replace...

Hello Folks, New to the forum. Just purchased a 2018 Civic SI Sedan in Rallye Red. I'm looking to do some fairly basic exterior mods. What should I target at first (low-hanging fruit) type of mods? Below are some things I'm thinking of but don't know the DIY complexity involved: 1. Changing...

Guys! Specifically, coupe owners listen up. Confirmed as of today (07/18/2018) WeatherTech has released new window visors for the 2016-2018 Honda Civic COUPE. Typically, I like getting my parts OEM if I can. If I cannot, then I try to look for a reputable brand aftermarket. When it came to the...

Want to buy for Civic SI front seats, message me if you are selling. If this post is still up then I am still looking for a set. Cheers

I drag raced against my friend with his tuned 1980 El Camino vs my stock 2018 Civic Si, and I won! We started looking into it, and the reason I won is because A) he has an open dif and needs a limited slip, and B) he needs more than 3 gears. He and I were basically side by side at the start...

Hi guys, so I'm debating on getting a four door car but I'm stuck between an 8th gen civic si or a 10th gen si or ex-t. I assumed the older si would be able to beat an ex-t with ease, but I've been reading on tons of sites that that is not the case, which I still thing it's some sort of fluke...

Good day to all you sirs out there!

It's been quiet, but we're always actively developing in the background. This feature has been in testing on our Si for a while. We've recently had this feature in the hands of multiple testers for extra feedback. Along with some extra quick adjustment options it's now very simple to setup...

As the title says, I am looking to sell my Throttle Pedal spacer. Condition is 9.9999/10 only because it was bolted to the car for 5 minutes and is not technically "NEW". Looking for $80 shipped obo

Used unlocked Hondata FlashPro, off my 17 Si. Will work with all 16+ Civic 1.5T. Asking $450, was $690 new.

#turbotuesday Today we’re dedicating this post to @27won. Their drop in turbo has allowed the #SiSePuede #Civic to make some sik power (180+ trq & 165+ hp gains). Proven to be reliable with countless roadtrips and races, we have officially nicknamed this turbo “The Sleeper”. Unless someone...

So I work for another car manufacturer, and have gotten criticism about my purchase. As we all know it's hot and our black interiors get pretty warm in these sunny summer days. I decided to make a sunshade. Let me know what you guys think. I'm trying to decided what design to put on a store...

I was playing around in the headunit settings and found the greatest thing. You guys might already know this but I’ve never seen it posted online anywhere. If you turn off the tachometer it doesn’t just go away, the shift light indicator replaces it Now I have both of my favorite style gauges...

Hey civicX folks! I have been a lurker for a long time now and finally took the plunge and traded in my Harley and my 2016 Sedan EXT in for a 2018 SI coupe. This will be my fourth civic i have had and by far my most favorite. I absolutely love this little driving machine. I picked it up last...
