I installed a progress rear sway 06 TL MT. The car has about 90k on it. The rear of the car feels more planted but now i notice more lift in the front once I accelerate and the front left drive wheel usually has more wheel hop now than i did had prior to installing. The front doesnt feel as connected to the road now. The car does not bounce in front and no evidence of leaking form the shocks.

Are these reflective of my suspension being worn (shocks, bushinges etc) or reflective of having the stock hollow bar in the front?

Thanks
