I have installed someH&R W124 (self-levelling) SLS and special equipment lowering springs to my non-SLS 300E AMG. One of my front springs snapped and I thought it best to change all of them, the rear AMGs are no longer made and H&R seem to have the best reputation.
Am I correct in assuming that the SLS rear springs are higher/harder then the non-SLS items? I only assume this as I have read here that Merc Sportline Wagon SLS rear springs are used on non-SLS saloons. I have an ICE install in the trunk so I thought it best to use the hightest rear-lowerring springs available!
One last question. Which way up should the springs go, flat part top or bottom?! Thank you
