what size of tires you guys use on your cobras? i have the stock 245/45ZR17 all the way around. i was thinking of putting nitto extreme performance tires on @ 245/45ZR17 in the front and 275/40ZR17 in the back. what do you guys think? will it make the ride bad? will it look stupid? is that normal? i will be lowing the car 2" if that makes any difference. thanks for any info!
