I've noticed an slight increase in road noise with the KW sleeve kit but no vibrations through the steering wheel. Sometimes it'll transmit a rumbling sound when you go over washboard-like road surfaces but it isn't felt through the steering wheel. I'd say look at the wheel alignment.

As for ride height.. you can't measure height by just measuring the collar. You need to put the car on the ground with the wheels on to get the height and then adjust the collars individually to get it right. Mine was off a good 1/2 inch from left to right despite the collars having the same adjustments all around. I think coilovers would be better in this aspect. Never had any uneven height problems before with coilovers.
