[vtectransplant]

I have run the following tyres on track on various cars....

Yoko A048
Toyo R888
Toyo T1R
Toyo T1S
Federal 595RSR
Federal FZ201 (road legal semi slick)
Dunlop SLicks

IMO A048's win hands down on everything apart from Cost. Slicks bring another dimension but unless you're competing I wouldn't bother. I spent nearly £600 on 13" slicks for my Metro vtec and the grip was good, but not twice as good as the £300 Yokos.

Yokos are not great on the road but amazing on track in ALL conditions apart from lots of standing water.

In the wet, they still work well as long as you get decent temp into them.

Ive just bought Yokos for the Saxo and Ill be buying some 595 RSR's as the 2nd set as they're better than Yokos and 888's in the wet and pretty good on the road.

Thats my input!
