I had some clunking noise from my HKS HAS. Found out it came from the dress up bolt kit I had on the shock tower. The bolts were just a little too long causing some rubbing.
It's hard to really capture it on a cell phone pic. One of those things where it's much better in person. Still have to lower it down and that's really gonna help.
I have a 21' with 1000 miles and I had this issue a few weeks ago where the car didn't want to rev, then when I put it in drive, it felt like it wanted to die. I drove a little bit and got a CEL. Checked it with MX+ and got a p0606 code. PCM failing its own self check. After about 3-4...
Yes, I'm definitely no mechanic and this was an easy install. If I had to say there was a hard part, it was the front lip. Mainly getting my hands in tight spots to put the supplied nuts over the bolts.
The trim kit added about 7-8mm in the front and rear. Also, it was the FRP version. I was skeptical how the whole rexpeed kit would fit, but they surprised me as it was spot on. I had a little issue with some white haze under the clear, but rexpeed stepped up and replaced it.
Freshly detailed and ceramic coated with Cquartz UK 3.0. Also, Installed Rexpeed V2 kit with fender trim kit. Great fitment for both the lip kit and fender trim kit. Waiting on my 20" Work CR 2 piece wheels and will lower it on HKS adjustable springs.
