Default "clunk"

am too starting to get that light sometimes (louder) "clunk" noise going over bumps slowly...... what can the dealership do to tighten the top when fully closed?

yes, but very very minor, though.

it's probably due to air pockets between the rubber seal, joints and metal brackets.

mine is very minor over bumps and I've gotten used to it by now.

If it's major noise, then it's worth checking it out.

Yeh I have the same noise on my sc430 as well... every time my car is 30 degree slop and turning it makes the noise. I found out it is coming from the right side on themetal thing you can see inside the car...(i don't know what that is called). But thats all I know if anyone can figure out how to figure it out tell me. It is annoying

I posted a tread on this about 2 months back and only a couple people came forward with confirmation of this problem. Now we have a few more. It is a real problem with the SC. The chassis flex is very significant. Suspension mods will intensify your chassis flex/roof noise.

I had my roof adjusted by the dealer about a 1 1/2 months ago. It almost went away completely. Unfortunately, It has come back some but is still "MUCH" better than when I brought it in for the repair. The adjustments were on the hinges and the locking mechanisms. The repairing tech said he believed most of the problem was in the locking mechanisms that attach to the front windshield.

Interesting,, we "flatlanders" from the East,, don't experience this problem, at least I haven't, however, I do have some "sqweaks" when the top is down and I'm riding down my gravel lane...

Thank you. That is precisely where it sounds like mine is coming from. I am going in to the dealer soon, I will report back what happens.
