I just got my full Megan racing coilover suspension installed yesterday and today notice that there's a noise coming from the passenger side front suspension every time I hit a bump it sounds like its bottoming out or knocking had any of you guys experience this problem and what was the fix for it thanks mahalo

I would do a quick double check and make sure everything is tightened properly.

I remember my old STi did that when I got BC coilovers. If I remember correctly it was due to a bad strut...? I don't quite remember but I just sent it back and got a new one.

Did you set reload on your coil? Some coil come in with out reload set.

It happened to mine, try to tighten the top mount ( pull out the dampening ****,theres a bolt that can be tightened) mine wasnt tight enough from factory

Yup that was the top mount bolt that the shop that installed my suspension didn't tighten so made it tight and now no sound thanks Club Lexus for you help
