i recently got done with my LCA/knuckle combo (based on Def's how-to). i used knuckles which were professionally cut and TIG'd for greater steering angle. i drilled out the knuckle to 3/4" and used shims totalling ≈1.7" (≈42mm) of roll center correction. i also drilled out the tie rod pickup point to 5/8" to use a heim joint and fine tune it's drop down distance (aka bumpsteer correction) with various collars and washers. the final product looks nice and made LOTS of angle compared to stock.
the only down side is the shorter pickup point on the knuckle gives less steering leverage, making it very hard for me to steer without power steering. sooooo i converted back to stock LCAs and knuckles for the time being. i may convert back to power steering later, we'll see.
in the meantime,
if someone wants to buy this setup (modded LCA's, modded s13 knuckles, outer tie rods, and all the nuts/bolts/spacers/shims/etc),
PM me. i'd consider selling it all as a complete bolt-in setup and just sticking with the simplicity of my stock stuff for now.
i wish i had taken a pic when everything was installed. lotsss of angle! haha
