[TR] Euro or other taller differential needed

[Jamie]

We're in Chumpcar.  Basically, the CC rules say that if you take the  
safety equipment/wheels/tires off the car, what you have left had  
better not be worth more than $500.  And we are trying to keep within  
both the spirit and letter of the rules....  ;-)
