My OEM Metzlers would prolly be okay, but there seems to have been an error in manufacturing. Instead of dead-dino rubber, the plant seems to have used dead-squirrel rubber. My Metzlers spin on hard take-off. What's worse, the rear tire seems to be made from dead-alpha-male-squirrel-rubber, as it always wants to come around and take the lead under acceleration leaving a sweeper.The metzlers worked as well as the Bridgestones and I wouldn't have any issues at this time with going back to the them. Except.... They seem to obviously have a belt seperation issue. So I will wait till they get that figured out.
With about 1500 miles on the OEM Z6s, I'm a bit disappointed in the lack of dry grip. I've got no experience in the wet, yet, but I'd be very surprised if the Metzlers are as good in the wet as the 'stone BT020s were.
