I have a front right clunk noise sometimes and I thought it was due to too much suspension mods. I have megan coilovers, polyurethane bushing and endlinks, h brace, rear tower bar, rrm sway bar and lower tie bar. It did not happen until I put on the H brace. I have since taken it off but it still happens. If I floor first gear and shift aggresively into second I hear a clunk in the right front of the car. It is very annoying. I am going to South Coast mitsu this weekend for a much overdo alignment and I am going to mention it to them. Hopefully it is not hurting anything. I checked all of my suspension components and everything looks tight and snug.
