If you have a family I would suggest going H&R, I think it's the only one available that is made for the 5, the Progress are the same springs as the 3's same part number and all...not sure about the others, megan springs will slam your ride pretty low. I'm running stock MS3 springs and an SPC camber kit, the springs sag too much in the back for my taste, I purchased a set of Tein H-techs, because they lower the rear less ( I have family too and haul stuff sometimes) haven't installed them yet. The H-techs are for the 3, but I also didn't realize the front spring rates on the H-techs are only 146lbs, the MS3 springs are at 188lbs or something. My reason for going H-techs was because the rear spring rate was 224lbs. So....wondering now if it's possible to run MS3 springs on the front and H-techs on the rear....
