if I had to do it again, I'd get cobb's in the rear and kartboy's in the front.
Kartboy's are padded so they're not as precise as the cobbs but I can't live with the pinging from the metal on metal in the front with the cobbs.
I don't think it's fair to say endlinks improve handling nor that getting just a sway is silly. The main benefit of endlinks is better handling feedback to the driver allowing the driver to make better decisions and adjust to what's actually happening with the car.
