I'm telling there some side effect ... well it bounce but not like a basketball ...lol. I might do the back this weekend. Might. Well I cut 2 lines and believe taking those curves at 60mph uffff is fun.... I can't wait to do the back as well. I slam the car b-cuz let me tell you 1. You feel the difference 2. You look good riding it 3. and 4 the envy people that said "can't do nothing to the Aveo" Well I keep upgrading the car and every time I do something people get amaze especially the Aveo's owner...they get curious and ask me how did I or where did I get the stuff for the car? I tell them I do it my self, and so far I've been getting good clients by the way. I want to finish getting the front lip, then the custom side skirts, and a surprise on the rear bumper you'll see the result. I'm trying to finish so I can go on a tour with my AVEO!!!
