I went to a test and tune yesterday and checked my car weight on the certified scale at the track. Over the winter I converted back to base brakes from z51 and mounted 2001 c5 front wheels 17 x 8.5 with 225-45 tires in place of the OEM 18 inch 245-45 18 and found my weight down from 3251 to 3155. I was pleased/amazed at the improvement.
