Im looking to give my 02 xtreme better handling. Has anybody had good luck with different springs iv allready started replacing the swaybar bushings with polyurethane.

Get bigger sway bars and lower it with coil springs and blocks or drop leafs.

im finding alot of springs that only fit to 01 is one brand better than another?

You can go with a ground force lowering kit from streetbeatcustoms.com for about 100 bucks and it comes with everything you need, my buddy used it on his s-10 and said it was a pretty good ride and increased handling by far!!
