i got on a tear recently looking into upgrades to solve the boat like characteristics of my 85 300d in a tight corner. as i live up in the mountains of NC it can be "interesting" on my way to work every day depending on which route i take and road conditions. so far i have looked at the sls conversion spring set that along with the second gen W126 brakes should help some however that still leaves the shocks and the front springs lacking a known good upgrade. the bilstein B4 HD shocks are slightly better but im looking into fitting something more aggressive. i have no issue driving something loud and harsh for extended time, as my other daily is a 86 F-250 with the 6.9IDI strait piped under the cab (which has the added benefit of dis-encouraging people to ask for rides or to borrow either car).
the question i have is how interchangeable are the various suspension components such as springs and shocks between the W126 and W123  cars? the W126 ran much longer and more performance options were available. so there is a slightly larger after-market which if compatible would solve some issues. there are also at least two companies i have found making coil-over kits for the W123 body. however i have not seen any reviews or found any proof that they do in fact work. (https://www.otakugarage.com.au/product/m...coilovers/) (http://pbbrakes.com/street-coilovers-kit...n-kit.html). the final question i have is directed to anyone who has worked with more race oriented equipment. how difficult do you think it would be to adapt the standard 5.5" or 2.5" universal springs to fit inside the spring stock perch with a hight adjuster? also what is the stock spring rate on a w123 sedan spring?
