I just got all of my suspension re-done, I used new top hats in the rear and front, and my buddy's 2003 cavalier springs, and GR2's. My god, it rides like a dream. There's no noise, rides very smooth, and was a very inexpensive upgrade from stock. I HIGHLY recommend GR2's for those who aren't drop who want a nice ride without breaking the bank.
yea i had them and i was gonna use them but the person i was gonna get stock springs from backed out and gm held my parts on back order so i found a complete suspension and just used that. i ended up selling them
