So I currently have K-Tuned coilovers on my DA9. I recently installed K-Tuned front camber arms and i’m hearing knocking sounds when i’m driving over bumpy roads. Mind you my car isn’t slammed to the ground but is mildly lowered (Because I prefer to drive a functional car, haha). There’s small bouncing up front like you get from blown shocks but the coilovers have only about 500 miles on them (Purchased new). I haven’t had these issues prior to installing the new camber arms. I’ve even tried raising the car and it a little better but occasionally i’ll hear the knocking and bouncing over big bumps at higher speeds.
Check your front lower control arm bushings and rear trailing arms bushing. I had the same problem when I was building my DA. I would hear a loud clunk when I went over bumps. The sound of metal hitting metal. After some inspection. I discovered my rear trailing arms were shot.
Ok so a friend of mine that also owns a DA as well as a DB said that this chassis is known for the UCA/Camber Arm to hit the shock tower. A solution to this would be removing parts of the shock tower for the camber arm to clear. He also did mention there are multiple companies like downstar that make shock tower extensions. Anyone else had this issue with their DA?
Very common problem for lowered cars with corrected front camber. You can run more negative camber, raise the car or cut the shock tower out for clearance, those are pretty much your options. Generally it’s personal preference regarding which option is best for you. You can also try different methods for camber correction as some options there will have better/worse clearance.
