Yes it is a GSR, Gsr's come with sway bars but i dont know if the LS's do. The ride is not bumby at all, with the blues I am very satisfied. I have Ingall camber kits in the front but i am not happy with those, they sqeek and one of them came loose. I have no camber kit's in the back but for soem reason i only need it on the back passenger side.
