Just wondering if any vendor makes parts to stiffen the chassis on the cabrio. I have searched but could not find anything.

Thanks

 

There are several underbraces available. The TSW is a good one: http://www.waymotorworks.com/tsw-xbr...6-r55-r57.html

 

any opinions on any of the braces available?

 

I have the m7 underbody strut system and I think it does work well. It braces in three places, the front near the radiator, the middle and the raer near the bottom of the strut towers. Combined with the rear upper strut braces, I believe I am pretty stiff. I do not know if these parts fit the convertible since mine is a coupe.
