RE: GDU pump test and case removal

20 hours is not great!! Although I have seen a forward gear starting to wear after only a few hours. I guess once the metal is in the oil it probably speeds up the wear process, plus once the case har...

Wonderful experience

I had my 'turn-over' day(s) for my SR10 with Radical Northwest over the last two days at Laguna Seca. I have never had the luxury of a full support team in an arrive-and-drive setting. It was wonder...
