Veering a bit off the topic perhaps, but there's always the choice of retiring the CS from tracking by picking up a higher mileage M2C slicktop with DCT to be built out for track use. Let that be the beater that takes all the rock and debris hits, hammers into the gators at the apex of a 60 mph turn, etc. Proper coilovers, camber plates, perhaps monoballs, Apex forged wheels, decent tires, BM3 CS tune, etc, etc. You could build it out while saving all the stock parts. When you're done with the M2C beater in a number of years, part it back to stock, sell it and sell all the parts.
I can't help but think the CS will thank you for that.
