This is pretty much my initial build plan for my PP, with 11" wide wheels and complete set of suspension bushings from a certain vendor :-DTo answer, I think it would be best for someone to buy a PP....then upgrade the bars, springs and dampers. Those mods, with some better tires, and you will essentially have a race ready street car, that will perform amazingly.
The Torsen and the brakes are what really makes the package (though the gauges are a nice touch).
