So far on my 2011 v6 I have an airaid cold air intake, bama custom tuner, front strut brace, rear tower brace, and soon 3.73 gears. But with this extra power I find my car sliding all the time, should I get Eibach sportline spring kit or just wider/softer tires?

 

Me personally I would go with some new wheels and tires. When you start on suspension you gotta do just about all of it at once from what I read. But you will love the look of new wheels and tires
