I'm new here. I have a 2006 V77 2.5T, 5sp auto, with about 130k mi. on it. I'm looking to do a few upgrades to tighten up the suspension, free up the exhaust and in just in general make it a more fun to drive vehicle. Being on a fixed income means I have to do this in stages. I'm thinking. 10mm wheel spacers, cat back exhaust, and new shocks and struts. It already has a k&n air filter. Sway bars? Bushing? Suggestions would be appreciated.
