i have a bad rattle right before vtec 5000-6000 rpms
i can only hear it when top is up

i have hardtop roll bar and custom 63mm exhaust

 

your saying like were suppused to know what the hell it is...how bout give us some more information

 

like?

 

Post a video if possible. Does the noise sound like its coming from the engine bay, tranny, exhaust, ETC. ETC.

 

it sounds like it comes from the rear u cant hear it on video

 

Post it in the rattle thread

 

i did no one answered there

 

Spare tire? Give us more info... No one wants to just guess blindly.

 

i have no spare tire...well im not sure wat kind of info to give

 

Check the rear tray in the center console... Check if exhaust is hitting any thing. License plate... Etc it also would be good to tighten up the
spare tire bolt, and make sure u don't keep anything the rattles in the trunk... Lol like a box of stem valve caps, or anything that could possible make noise. And that goes for any storage location in the s2000...

Thoese are just my two cents..

Good luck
