Good luck. Make sure you get a set of aftermarket rear-shock-mounts. The stock RSM's are prone to crack with aftermarket suspensions and the rubber is known to wear out prematurely, especially since the H&R coilovers will offer pretty stiff ride, combined with 19" wheels. You don't want to save a couple hundred bucks by not getting these parts, only to have to spend a lot more when they fail (parts + installation/wheel re-alignment + hassles dealing with accessing the rear shock towers, especially if you have a roadster). Rogue Engineering has a type of RSM that allows you to install and uninstall the rear shocks externally. TCK also sells very good quality RSM's.
