H&R springs. Without a shadow of a doubt, our favourite spring manufacturer. Not as stiff as some competitors, H&R springs give a noticeable improvement in stability while maintaining ride comfort. Not the raciest feeling spring but in our opinion, a great spring for a daily driver driven hard. If H&R springs are so fantastic, why are they not fitted by the factory? One word cost. H&R springs cost a lot more than the car's standard springs.
