I have these on my Sport with H&R -50mm springs and I am loving them.

Is there anything else I could do the the suspension setup to maybe imporve the handleing again? I hear that I don't need those 'bump stops' things

I was thinking about changing the front arb to a 22mm? like I have on the rear.

 

Solid drop links front and rear
adjustable top mounts front and rear
camber bolts
uprated anti roll bars
front, rear top and bottom braces
polybush's

 

cheers for that.
