I bought 2 x Falken Azenis RT-215S's for the rear, about 2000km ago, i must say i'm very impressed with their grip levels. Only had them let go once, and that was severe provocation... i.e. 90 degree righthand corner, 1st gear, full throttle, up a hill. Even then they didn't let go in a big way, they still kept gripping, and pushing me fowards, where my old tyres would have just been a plume of smoke, with me not accelerating very fast at all.
Edit: P.S. They were 205/55/16's to fit onto standard R33 Rims, $255 each.
