I have a 2007 base XLR and while I've attached the XLR-V rear sway, the softness of the setup is not to my liking. I'm wondering if any of you guys could point me in the right direction to correct this. Will just lowering the car tighten the suspension up? Do I need to replace the shocks as well? I'm also wondering if there is any adjustability in the stock setup in terms of ride height... Thanks for any help you can provide.
