H&R uses bilstein parts but different valving. B8 is a digressive valving where h&R are linear valving and softer ride but have more rebound dampening at higher shock velocities. H&R are more similar to the ST dampeners which are also a linear valving. I've had all 3 and also had all 3 dynoed on a shock dyno to understand their dampening curves and dampening forces. H&R and ST use very similar spring rates so these would pair well with your rear springs. B8 uses a 46mm piston where h&R uses a 36mm piston on rear shocks. Both are larger pistons than you will find in a ST or Koni shock since Bilstein and H&R are monotube and ST and Koni are twin tube.
