Hello ! So recently i’ve been attempting to get my E30 aligned properly as the car does not self steer back to center and appears to be ‘crab walking’ when driving in a straight line.
modifications :
Front: E36 BC Coilovers / Knuckles, GAS (FAPO) E30/36/46 angle kit, E46 Purple Tag Rack
Rear: E30 BC Coilovers, Poly trailing arm bushings , Poly subframe riser bushings, Normal Poly Diff Bushing (not raised) 5 Lug Conversion, Toe / Camber Eccentrics
Method : A combination of Toe plates and string alignment. the string is measured from axel / wheel bearing nut on each corer and adjusted so that the string is equal distance from each front and rear independently. when these numbers match, i’m confident the string is parallel to the frame.
Questions:
1) when pulling back steering rack boots, i’ve verified that rack is centered among itself (inner shaft same distance from outer rack housing on both sides) , but when i zero out the toe i am clearly seeing a difference in exposed thread on the outer tie rods. a. is this okay ? and b. why is this? is the rack not centered among the chassis? i am fairly certain that caster (lollipops) and camber(tophats) is the same on each side.
1) in the rear, i have zero toe in reference to the strings (parallel to car) but i believe the rear thrust may be off. crude measurements show a slight difference in measurement from wheel to front of rear arch. i believe this to be the cause of my ‘crab walk’ issue. is there any way to correct this?
Car has a clean title and does not appear to have pickups damaged also.
Thank you in advance !
