I've just had a rear M3 fitted and have a 014 on the front.
Two trackdays back I ran 014's front and back, this was not fun at all, the rear let go on me 2 times, once at turn one off pit straight, and a huge moment at turn 3 doing prolly 140k's.
The GSX-R day just gone I had the m3 on the rear and 014 on the front. The m3 was bullet proof, well it did move a bit when fully leaned over trying to get the power down, but I thought it was exceptable considering it's a sport/tourer. Still prefer to run a slick but would be happy to go on a trackday with the M3.
