At the moment running on my s14:
Bridgestone re070 semi slicks on the front
Khumo something or other sport tyres on the back with a v tread. 203s or something.
The re070s are brilliant - they wear well, are super responsive, super grippy, good in the wet.
The khumos are surprisingly versatile and have lasted really well with a bit of abuse.
Next change I'm going Federal 595rs semis front and probably federal street tyres rear. See how it goes.
