SVT Shelby GT500
Just purchased a 2011 GT500 SVT. I have some questions.

[QUOTE="Bad Company, post: 16985154, member: 141815"] These cars can get away from you quickly, as they can produce a snap oversteer situation while hard into the throttle. You asked for tire recommendations for basically running an all-season tire on the car. The responses you've gotten were recommending a dry weather summer tire. Yes it gives the best traction on a hot summer day, but the drag radials will not work in a heavy rain or in the winter if you got caught in a snow storm. Also to increase tire sizes to the 315 width at all 4 corners requires a serious amount of suspension modifications, along with a new set of wheels. To utilize the stock wheels I'd recommend the Michelin Pilot Sport All-Season 4 for the ability to use the car all year with the ability to drive it whenever you please. Now to get caught in a snow storm with this car is asking to get in an accident at the worst or having to abandoned the car at the least. In the winter months I'd watch the weather and if any weatherman indicated the slightest possibility of snow in his forecast I'd drive a different vehicle over this one all of the time regardless of what tires were on it. 550Hp in any car without a lot of traction on the drive axle is an invitation to disaster in snow. Now if you want to get serious about suspension modifications that will greatly improve the snap oversteer issues when your in the throttle I'd use CorTeX Racing's Watts Link, Torque Arm, Rear Lower Control Arms and relocation brackets with the 2013-2014 rear sway bar. Up front you can utilize the stock K-Member and front Lower Control Arms with an Eibach 36mm adjustable sway bar.
