I don't race my car, other than to dust every Mustang GT that asks for it on the street. For what it's worth, I just put on a new set of P245ZR40x18 Goodyear Eagle GT's, and am pleasantly surprised at how well they grab, wet or dry, but I also replaced all suspension and chassis-related bushings, including differential insert (Pedders), big bore shocks and GSRII struts (Pedders), 1.25" Front & Rear Drop Springs with rear spring insulators (Pedders), and (G-Force) modified trailing arms. Alignment is good too. The car handles exceptionally well compared to OEM, and, for the money, the Eagle GT's grab really well for a $169 tire. But once again, I haven't been a track goer, so, other guys have better knowledge of a good street/strip tire. For comparison, I have used Ultra Performance Hankook and Nankang tires, and both of those are **** compared to the Eagle GT's, but they are cheap tires.
