#39, "RE: Are the rear rotors on a 99 GS with all wheel disc solid rotors???" In response to Reply # 0
From what I know, all rear rotors are the same size and solid and the fronts are different if you have an AWD. The difference in the rear is if you have a RS with drums or GS/GS-T/GSX with rotors. Also, when you order the powerslots, they should specify the year anyway so it shouldn't be a problem. Plus they are all slotted regardless.
