Just bumping an old thread as I installed these tires on my 2015 3 GT on the weekend. What an unbelievable difference between the Michelins and the stock Dunlop SP 5000.

I was initially disappointed in the handling and especially the feedback on the stock setup compared to my old 2010 3 GT. I thought the move to fully electric steering had dulled the response but the 2015 now handles as well as my 2010. The Michelins are AA Traction versus the Dunlop which is B Traction and 500 Treadwear on the Michelins versus 340 (I think) on the Dunlops. I'm not normally a Michelin guy as I find them expensive but got them on sale at Canadian Tire last year (just didn't have time to mount them until now). It also tracks much better and so is less tiring to drive as you are not forced to make constant steering corrections. Acceleration is more stable as you don't have that sort of wandering feeling.

The only positive of the Dunlops were that they were *slightly* quieter with less road noise than the Michelins.
