GC, my Beemer lost a wheel on my poxy little two straight, two dragster turn circuit. When I investigated it appeared that the axle was way short - if I pushed the hub back on all the way, the inside would be rubbing on the chassis.
While we are at it, I had a bad week this one gone, my Cartrix NSX suddenly sloooowed at the Oxford track and both wheels were found to be loose. I guess our track is too bumpy.
"Things come in threes", old ma Wankel used to say. Nervous about my Daytona now but she'll not become a shelf queen - that's the Daytona, not my mum.
