Hello to everyone here on this great site. I recently purchased and installed a pair of raybestos professional grade variable rate wagon springs from rockauto.com. They are part number 5911055. inside diameter is 4.07". The wire diameter is .554" which is about 14.07mm. I installed these on an 89 244DL even though there for a wagon. The old springs that came with the sedans had a coil diameter of 12mm. After I installed them I noticed right away the restored ride height. however i haven't bought new shocks yet because i dont know what kind of damping (compression and rebound) i need to match these springs. right now the ride is bouncy. i'm assuming the shocks are original too because there was undercoating on the shock and spring hardware. I definitely want to go with bilstein HD. model # 24-002967 has 225 compression and 107 rebound. they offer another model # 24-022118 which has 275 compression and 200 rebound. Any advice on the right shock for these springs will be greatly appreciated. 022118 is 60 USD more each then 002967. thats about the same price to have bilstein hd custom valved.
