I don't track my Boss,I would like to atleast once,but I see alot of problems on here with the Bosses drivetrain,rear ends,transmissions,and drive shafts.Is this just the Boss or do the Shelbies have similar problems.Are these parts stronger in the Shelby's.I have run my car pretty hard numerous times,taking it to 7500 RPM's through the gears with no problems at all.Are these problems due to tracking the cars.
