Federal 595 RS-R one mine. Cheap, sticky, and seem to last long. Dry grip on track is great, levels above T1-R, and wet grip is better than your average street tire. Rears are a little less than halfway through with 17 000 km on clock, fronts little over half, which is normal as mine's a 4x4. When the grip goes(never happened outside of a track), it's gradual and easy to control.
Only downside I've found is that they're noisier than normal street tires, but as that's not an issue with me, I think I'll stay with these.
