I have put the 034 Rear Sway Bar on the car, its solid and 25.4, adjustable with the the soft setting at 215% increased stiffness and the hard setting at %290. I set it to hard, with 034 spherical end links and this thing keeps the car flat during turns and may be one of my favorite mods, definitely my top 2 favorite mod for under 300. Technically you will not notice anything because when you turn aggressively you shouldn't have to keep compensating for under-steer. I am not sure how other people have modified their cars, but I have Bilstein PSS coils on the car and they are 25mm lower than stock in the front and 20mm lower than stock in the rear. I do not notice any aggressive changes when speeding at highway speeds (or track speeds). Now another big one would be tires, I am running DWS Extreme contact and not summer tires, so I have not lost traction but summer tires might enhance that drastic feel you may get at faster speeds? If this is a daily driver, buy either new OEM rear end links or whiteline ball joint endlinks. Do not buy spherical end links unless you are tracking constantly.
