w123/w126 suspension interchange/upgrade
the w123 estate has a larger front sway-bar but everything else is the same with one exception in that the rear brake calipers are about 1-2mm bigger pistons. the w126 brakes are a direct swap for first gen and second gen if you have 15" wheels or bigger. my issue is the lack of significantly stiffer suspension components that would fit without extensive work. it looks like the w126 shocks are the exact same as the w123 and billstein has a B8 sport package for the w126 that is still available. the B8 shocks are designed for lowered vehicles so thats an option for anyone interested in lowering while maintaining proper shock valving. as for springs the w126 has slightly taller springs but the same width (475mm hight average in front vs 450mm for the w123). so it looks like im going to go for the sls delete springs in the rear with a 1.5" drop and a set of 300sd front springs cut to 1.5/1.75" drop. as for shocks im looking at the koni reds as i would like the adjustability they offer vs the bilsteins. i would like the lower valving the B8 shocks offer but im afraid that the stiffer rear springs and shocks might make it oversteer too much and would prefer to be able to dial in more or less as needed. otherwise that still leaves the rear sway-bar as an issue with no clear solution now that the 16mm version is NLA. has anyone looked into swapping in a universal torsion bar set up? i feel that you could find one the proper length and then its just a matter of making arms that would work with the stock fittings.
