I've just spent a frustrating sunday afternoon trying to fit a set of lowered and stiffened springs (along with new dampers and rubber bits) to my '79 320. Thought the springs looked a bit short out of the box - despite being advertised as 40mm lowered, I measured at least 50mm lower from normal. This meant that the tyres fouled the wheelarch completely and I had to take them off again. I have later 14"x6 rims on (and 10mm spacers), but with lower profile rubber the diameter is only up 4mm on standard.Has anyone successfully lowered an E21, and if it's not possible, how can I make it roll less round corners? Can I move the front wheels back a little bit in the arches to make the springs fit? I've checked the archives for help on this, but a definative answer would be nice.
