the bormann 6, my trusty 88 528e, has acquired a drift, a kind of sudden sideslip almost like a gust of wind. any insights. car has 230kmiles. unable to take a look at yet. what should i be looking at? worn out rear suspension stuff? its pure stock right down to its 14" bottle caps. would a 4 wheel alignment be of any use? i know the front needs the toe in checked, i swapped out the left tierods to get by inspection. this swooping thing is newer tho.
