So, I am thinking about upgrading my suspention by adding ipd anti-sway bars but am hesitant to purchase them for fear that getting them installed may cost more than the parts themselves (I'm on a budget here!). According to the ipd site professional istallation for an s40 takes 3-4 hours. Now, I know the s40 is a totally different car than my 850, but am fearful that the situation may be similar for my car. Has anyone installed these by themselves or had them installed? How long/how easy/special tools/etc. I'm hoping to install them myself but don't want it to be sometbing I could easily screw up. Thanks!
