Could someone give me some advice of wheels... we started karting late last year and received 5 sets of wheels and tyres with the kart, all a bit worn.  So I bought a set of Jet wheels to put a new set of slicks on.
  The fronts wheels have an offset or around 65mm, which I didn't think much about at the time.  Only a bit frustating as the next best set of tyres were on a set of mag wheels with an offset of around 50mm.  Therefore the front track had to be adjusted every time I switched wheel sets.
  Now that we are getting ready to start up again, I've measured all the wheel sets in an effort to make life a little easier at the track.  I've found that all the other front wheels have an offset around 50mm (Ali and Mag)... should I have specified a front wheel offset?  Or are the the wheels I'm using as front wheels really rear wheels, as rears all appear to have an offset of roughly 65mm?
  Thanks Jim
