Matt car: 10,000+ miles per year

Your cars: so without any real idea of how often you actually run any given race car... 1/4 mile at high rpm and a 1/4 mile back at low rpm for X number of runs that day, for X number of days between rebuild.
Maximum 1500 miles per year here for not even 50 runs a week.

thats a world of difference.
