First off, when is that last time you saw a Porsche in a parking lot up on cinder blocks? They are 100 times more likely to steal your car then your wheels. That said, I'm sure you could find an aftermarket lock that is silver in color. Oh, and what size tire did you go with up front. The 225/45 was the key for allowing clearance. Only problem is that is reduced my ride height another 1/2 inch so I'm sitting up front with 23.5. Ouch on any curbs of ruts.
