I adjusted my tbars also you can see the difference here:
before:
After the tbar adjustment and accessories and tires:
Now that I added the larger tires for some reason the ride is much smoother - eventually I will get a suspension lift so for now the ride does not bother me.
{I know I spelled 'adjustment' wrong - this is what you get when you're rushing..LOL}
In this picture the rear is 10 inches from the tire and the front is 9 1/2 I think I turned mine about 5 times. And yes, jackin' it up does help - well it did for me, turning it was quite easy after I jacked it up and from what I've been told it is the proper way.
