New owner here and I'm wondering if, 1) the GS sway bars are more aggressive than the ones on the TourX, and 2) if they will fit on the TourX? Swapping sway bars is a method I've used to improve lateral handling without compromising the suppleness of a factory suspension; I'm not interested in changing springs. Alsodering where to find OEM Regal/TourX parts online. Any suggestions are appreciated. Thanks.
