I have already spent several hours looking into the subject of front shocks.At this point I am leaning towards koni sport over any Bilstein because of the harsh road feel.The ES has slightly stiffer springs as stock in the front ,all I want to do is find the right shock number to match the original springs ,no lowering or any other changes to be made.I have looked at a number of sources for the konis and have found a variety of different manufacturer numbers for these ,my question is ,which is the correct number that I need ?
