Best, Easiest Brake Upgrade W124 300TD
There will be a ball joint/rotor clearance issue with your early lower control arms. Later control arms have a non-replaceable BJ with better clearance. I don't know what the cutoff date is. R129/W201/w124 LCA's all interchange.
The 140 calipers won't work, in case you didn't already know.
The R129 spindles are thicker and use different bearings. Less flex if you autoX or track it. The W201 16v EVO II used the R129 spindles.
320mm rotor setups can fit under 17" wheels if they have caliper clearance. Anything bigger and you need 18's.
190rev has a lot of brake part interchange threads, a sticky too I think.
