I installed the Caliperfexion brake caliper studs on the GT350 today. I got the sleeve extensions too. If you track your car, these are a must for cost savings and easy of changing the pads.
The factory bolts are one-time use. I got 1 1/2 track days out a set of front pads. The pads at $250 plus are bad enough, but spending another $30 on bolts that literally strip a little bit of aluminum out of the knuckle every time you change them is way too much. And I don't want to spend $500 to replace the knuckle after a few track sessions... that is just way too much.
