a friend had the S13 struts and brakes in his 1200 sedan - there were serious geometry issues. ie if you were reversing anywhere near full lock, it would just seize there - you had to go forward a bit and really force the wheel back to straighten it. couldn't se any signs of fouling on anything when it was seized, it just bound up on itself.

steering was very quick with the S13 arms though - probably part of the problem. I didn't look into it any further than that, but suspect it had bump steer and scrub radius issues at the very least.

highly unrecommended conversion
