well I guess it depends who is doing this. I don't know that I would trust anyone than a Porsche-trained facility to do this.
My fahter had this done on his old Volvo years ago and it was like $900 back then.
Which I thought was outrageous given the value of the car at the time. Allot of money to spend on something that wasn't going to noticeably improve the Volvo.

but now youre talking Porsche.
If you can, I'd skip it unless you plan to keep the Boxster forever.
