I'm only halfway thru the build, and not counting my mistakes, the build is not as straightforward and smooth as the RB5 IMHO. Mistakes in the manual don’t help: Step 12, the orientation of the ball cups showned on the steering tie rod and front upper rod are reversed. And surely having 3L at both ends of the steering tie rod, with the distance between them at 21mm, the ball ends are now fully screwed in with no room to maneuver, and when you attach to the car, you still have huge toe-in. I am guessing this is a misprint, you need a 3L with LL, or both LL even.
