Lowering your Scion tC causes negative camber (when the tops of the tires point in), which in small amounts can improve turn-in response and overall handling. Too much camber will cause short tire life, and skittish handling. Eibach camber bolts for the front and axles are a simple way to get your lowered tC properly aligned or a simple way to make your stock suspended tC handle better. Installation is easy allowing camber adjustments to be made accurately and easily. Sold as sets per axle.
