i generally run 200/55 on my gen 1, can't say noticed massive difference from the 190 it used to run, generally pirelli rosso corsa of some sort, though had bridgestones originaly. I've jacked the back up on the ride hight adjuster so not tried the 60 profile. couple of track days a year mostly road blasting about 5k per annum. havent needed to do anything with TC but run in slick most of the time anyway
