Ok, wife won a eibach rear sway and since my r55 already has one it will be going on her convertible. I read it has a hidden 5th bolt holding subframe but I have searched and googled with no joy.

I saw a video that says just cut a hole to access and tape over it etc, I'm fine with that as I'm not going through the fun of removing heat shields.

But be nice to know were it is , someone got a link to a pic or drawing
showing were to make a hole.

 

nevermind I found it, I found that using a cargo strap to pull muffler to one side really helped alot.
