BM, expect it to cost about $1,700 give-or-take $1K. The kits for the 997 are about $1,800. Plus labor to get it installed. If I do it, I will order from Sunset Porsche (Phil Coy is the contact)...no sales tax...about $75 for shipping.
Heck, PSE kits for the 986 still run about $1,650!
I may have to ask Mark (Houston C4S) for a test-ride before I spend the moo-la$$
