Just got some Toyo T1Rs on my SP23 a few weeks ago. 205/50/17 were $225ea fitted and balanced. Compared prices (in 205/50/17) with Falken FK452 @ $229, OEM Bridgestones @ $230 ea, and Dunlop SP SPort Max @ $330 ( )
Grip is better than the OEM Potenza 040's, however there appears to be a little more sidewall flex on turn in. Once settled the car is beautiful through the corners.
Overall Im very happy with them, especially in the wet. Price wise they were great, however I was advised that for the skyline (235/45/17) the price was not so comparable :S
Dry: 8/10
Wet: 8/10
Value: 9/10
