You might need a wheel alignment again man. One thing to consider as far as steering input is having your caster adjusted because it's caster that is important to steering feel and high-speed stability. Having your negative camber adjusted more towards the max spec can also aid in steering sensitivity as well. If you're using the Bils 5100's, and you have them maxed out, some have complained about ride being bouncy as well. If you're running spacers then your low profile tires are more to blame for stiffer ride.
