I've e-mailed sam about the parts, I know everyone that used to run FSR's here stopped running them ages ago (stopped making them?) but I remember still seeing a kit in there not too long ago. that doesn't mean they've got the parts though. You're best bet if they don't have the parts might be to pick up one cheap second hand. there would be a few out there as no-one runs them anymore.

And yes, racing still going at Shenton
