The handling of the boxster is one of the main reasons I brought it.
I brought a strut brace for my previous Mz3 and IMHO a strut brace is not needed for the box.
Thanks for the product review on the Max-speed brace. I saw it on ebay and wondered about it. It looks just like the RD carbon fiber brace. According to the seller it is a "no-name" manufacturer so I wondered about the quality. Sounds like its a pretty good deal.
