Price Range $0-$250

What tires do you guys recommend? Im on 235-45-17 tires now...
Does that affect my gas mileage? I went from 215-55 to 235-45

Here are the tires im currently pondering...

Goodyear Eagle GS-D
Kumho ECSTA KH11
Michelin Pilot Sport A/S
Falken Ziek 512
Bridgestone Potenza Pole-Position

I run my car at the track alot, no SCCA stuff.
My Falken St-115's have NO grip,

Thanks
