From the Research i have done but never used them any of them ,,

KE20 Corolla, has the same 80mm distance bolt holes with a shorter arm ,

the last model sigma also has the 80mm bolt hole and shorter arm .. but the ball joint is offset close to the disc which could be a problem , you would need to run the 200b ball joint as well or mod the sigma lower control arm ..due to the Larger taper ball joint ..

also if you are use s13 silvia struts/hub it gives you shorter arm as well ..

also the early Mazda use the 80mm bolt distance ..but the steering arm seem about the same arm lenght as the Datsun ,,

any one got other ideas ..


you would have to check your bump steer after using what ever set up ..
