Clutch pedal is making noise

Recently installed an em2 cmc and now my clutch pedal is making a noise. During installation I even took the whole pedal assembly out to inspect it and I put a brace on it. Every gear shifts smooth but the noise is throwing me off.

New to car modding! Best daily mods for 2010 Acura CSX (K20Z2 automatic) + Mugen body kit advice in

I recently picked up a 2010 Acura CSX base model here in Canada with 140,000 km on it .K20Z2 engine (Automatic).

This is my first time diving into car modifications, so I am a complete beginner! I want to turn this into a fun, snappy daily driver. I know it’s not the Type-S, so I’m not trying to build a race car—just something that looks clean, sounds nice, and feels sharp for everyday driving.

I'm eager to learn, so please break things down for me like I'm new to this. Thanks in advance for any advice!

Hondata tunes for track

Hey everyone, I have an fg2 and take it to the track every couple of months. The only engine mod I have is a k&n typhoon (came with car) and I just bought Hondata. Is the Hondata k n intake preloaded tune safe to run on my car while going to the track? Also what’s a safe red line with stock engine. Thanks

Cold start rattle, fresh VTC actuator spring

Hey guys, hoping someone may have some insight on this one. I used to get a cold start rattle in the winter, and that was my VTC actuator going bad, replaced the spring and the noise never came back.

Fast forward about 6 months, just starting yesterday or the day before, I’m getting a slight/moderate rattle sound similar to the VTC actuator, and it goes away after like 2 seconds. Ambient temperature is about 26° so it’s not because of cold.

I’m just over 100k miles, but I know the timing chains are supposed to be lifetime, however I have over-revved the car one time about a month or two ago, so I’m curious if this situation is that money shift materializing.

I have a new OEM TCT in my garage I may try to install when I’m home. Also I noticed on idle it sounds like I have quite a few backfires or misfires, an irregular idle. Does this point in any direction?

TIA everyone, I’ll try to get a video tomorrow morning.

What happened ?

This is directly under my passenger seat.

I noticed the floor mat was visibly sticking up and i went to push it down.

The metal of the car is warped upwards. That picture shows the metal warped upwards.

I don’t remember hitting any curbs so I don’t know how this could happen, but regardless anyone know how I could fix this.

I see that the clips came loose but how would I push the metal down….

Anything helps haha

Tune required for exhaust?

I’m looking to upgrade my exhaust setup to a skunk 2 alpha headers and the megapower rr. I did a quick google search to see if I need anything else and they are telling me that it’s required to have a tune or else it will run like shit. To anyone who has the same exhaust setup or did exhaust in the past, did you guys tune after and if you didn’t did you notice a huge difference in how the car ran wth no tune? Pls lmk thanks!!!

Is this just a tachometer malfunction?

Just picked up this FA5 about a week and a half ago now and I noticed something kinda weird. The vtec in this car engages at 4400rpm and revs to about 8700rpm according to the tachometer. I messaged the previous owner about this and he said the car had never been tuned and the only thing that is done to it is an injen intake (does not require a tune like others) and some hasport motor mounts, it even still has the stock exhaust. Does anybody know what could cause this and should I refrain from taking it to redline? If I remember right aren’t these cars supposed to engage vtec around 5500 rpm and limiter is at 7800-8000?

brake lights stuck on

last night getting out of my car i noticed my brake lights were stuck on even when the car is off or in motion. i looked it up and ended up finding broken parts of a little blue ring that holds the brake pedal to some sort of white stem sensor. i decided to disconnect my battery overnight so it didnt die overnight. is there any solutions to this i'm not seeing?

Best looking wheels for FA5 in 17x9 +35?

Really wanting to get some new wheels on my FA5 and ditch the heavy and weak XXR’s and switch to a 17x9 +35 to fit a 245/40r17 and will take track abuse. I’ve been thinking of going with the old reliable silver enkei rpf1 since I’ve always loved the look on these cars but if anyone else has some more recommendations I’d love to hear and see them.

Headlights

Hey everyone, I’m looking for suggestions for headlights, I’ve had two sets of all chrome headlights in my civic in the past two years, each set only lasted a few months before turning yellow, I’m assuming most all of those cheap clear headlights are the same and will all have the same issue, is there any reasonably priced headlights for my car that will not yellow or break fast or would I be better off just sanding them down and throwing some 2k clear on them? Thanks!
