I believe my track days numbering in the triple digits, thousands of autocross runs, SCCA regional Solo 2 championships, and multiple endurance race podiums (LeMons) give me a pretty good knowledge base for offering an opinion in this area. In my opinion, a slight improvement in caliper rigidity is not worth the hassle when the required bracket is big and difficult to make and the pads are expensive. In my experience, I get good performance and pad life out of stock BMW brake systems with their single piston sliding calipers. Bolt-on factory upgrades such as a 330 system on a 325 provide huge performance for dollar. If the Boxster S caliper offered a significantly larger pad volume and longer useable track life, I would suggest trying them. They don't so I don't recommend them.
