I swear I searched at least a dozen different ways to find this answer to no avail. I am trying to find out, just how much harder are the H&R Sport springs on your stock shocks? The car has 48k on it and figure they will need replacing soon anyway, which points me to coilovers. But for the sake of the argument, are the sport springs worth the price saving? We all know that basically once you get the ride height set on coilovers you pretty much leave them alone. anyway. Oh forgot remember the car does see the track guys.
