^^^ had the same problem with my AE80 front. if u using the foreign used 12 valve 3A or a 16 V 4Age with OD tranny or even if your suspension is just worn i suggest gas KYB shocks in front and the slightly stiffer foreign used springs in front. i did that a few years ago and kissed that problem goodbye forever.
i'll be doing an overhaul on the suspension on the AE80 in the toyota 4age/3sgte thread. just see page 1 for the index and if its there you'd see it in the index in the first post on pg 1.
could just be me guys but now is a bad time to plan a crew lime. maybe after xmas we could hit a cooler fete together with the "toyota models" or something
