UK member here 2003 xfire Coupe Auto 60k. Michelin Pilot Sport were fitted as standard from new. Lasted 32k on rear 42k on front. Replaced rear with Pirelli P Zero Rosso lasted 11k, sticky but wow the wear rate! Now on Conti's doing OK with 16k on them but more than 50% worn now and liable to give way without warning near the limit. Had Kumo on the front and they were OK but hard and noisy and tram lined something awful. I had to replace them due to a tracking problem after ball joint change and have returned to Michelin. God I didn't realized how much I missed them.
Stick with Michelin costly but worth every penny.
