here's an idea
ke30 control arms in ke20. ben, you own both cars, see if this is a bolt up possibility? then you'll have control arms with 14mm balljoint, then you could use ae86 p/s arms with xt130 struts (like fook did in pinky) or even ae86 adjustables which you should be able to buy pre-made if option magazine is anything to go by
you could use anything with 14mm balljoint thread really, i think you can get control arms bushed so they bolt into an originally smaller bushed car (right fook?), so wrecker hunting for celica/corona/cressida/scorpion control arms would enable you to run a pretty wide range of tracks and cambers
you'd probably need flares front and rear (already need them rear anyway) to run anything wider than a steelie
basically, to put different struts in a ke20, you HAVE to go backwards with steering
