I bought these tires last week to replace GoodYear F1 (steel belted showing). I bought this car a couple of months ago. The F1 was at the end of their life, so I can't comment on those. The Continental traction is great for everyday driving and accelerating. Handling is awesome even on wet roads. I can't comment on snow because we rarely get snow. It is probably in the 40's now and I raced a Trans Am red light to red light, easily taking him. The traction was great if you don't dump the clutch or drop the hammer. 540 HP at the wheel and something it gotta give. The second round with the Trans Am. I come to a stop because of traffic and he changes lanes. So he gets the jump coming around me. So I dump the clutch and drop the hammer. My brand new Continental extreme contact start spinning, the back end start fish tailing and then it hooks up and lauches me. These are great all around tires for everyday driving. I'm not a track driver but I enjoy the occasional street race. It is evident to me that I require two set of tires. These for everyday travel and a set for road racing. I will look to purchase a set of 555's and rimes for the rear. The supercharger is a beast and so far nothing has fully hooked up. If it ever does this thing will lauch into outer space. I have a stock set of SVT rimes, so no one carries a road racing tire in 19in rimes. I hope this helps your choice on purchasing these tires. Tire Rack purchase was flawless. I highly recommend tire rack and I search for two weeks on line before purchasing my tires from tire rack. Several places advertise no shipping but when you compare prices that is a false statement. My tires arrived in two days with standard shipping. These guys are awesome, even the local tire dealers recommend tire rack. They can't come close to touching these prices.
