I have had similar problem when i was going round a tight and sharp bent, was only doing 30mph and the TC kicks in. My bridgestone RE040 fronts are near the legal limits. Have just bought a set of 4 falken 452 from Camskill for just over £400 delivered. After reading lots of post here on mixing tyres, i have decided to change the rear as well to Falken even though there is still some life left in them. It's money or my safety and i chose the former. If u want the Falken 452, i would put in an order sooner rather than later as they sell very quickly. I have to wait for a pair of 245/45/R18 for couple of weeks as Camskill has run out of them. It's in the stock again. My tyres should hopefully be here tomorrow
