I've managed low 59's in our little golf GTI when racing, but never been timed in the GT3...always wondered what it would do though, but as I'd never use it on a test or race day I guess I'll never know.
Spyderman, not sure who you do your arrive and drives with, but I was chatting with a sales guy from RPM (I've no links with them, so no vested interest). They prep cars that are used in your series and had one of their cars out on track at Brands. It looked pretty sorted, so might be worth looking into if boxsters are going to stay the car of choice. All the best saving those pennies, you never know we might end up on track at some point so let us know what series you end up in.
