Another Tire Conundrum

[Topless]

Typically "Toe in" burns up tires far faster than negative camber. Try a Zero Toe setup front and rear and see if you get more miles while retaining good aggressive negative camber. Also some guys who street their R comps will flip their tires on the rim every 2000 miles or so to extend their life. I think the Michelin Cup has a dedicated outside shoulder so you can't flip those. With Nittos and Toyos you can flip them for longer life.
