OK here it goes, When my car had the stock Rims and tires and springs I could run it up to 125+mph or so and the car felt tight to the road, I changed the wheels/tires lowered 1in with springs, Now at 125 it feels loose in the front like it's walking side to side. Kind of scary. I took the settings pdfat gave for Performance street and the guy told me it would eat my tires off. Instead of arguing with him I just had set it to stock. Still feels lose at high speeds.
MY question is if I have them set to pdfats setting will it fix the high speed problem? and will it make it eat the inside of the tires off faster?
