Anyone have an opinion on the Ground Control coil-over kit available on this website? Not looking to knock my fillings out, but do want to tighten the ride and am willing to do damper and springs if that is a better route to go. Looked at the Apex kit, but seems pricey. I commute on the highway with the car everyday, but I want to maintain some livability with the ride. I am also considering bundling the suspension upgrade with an OZ/Michelin wheel package.
