It seems to me a freshly built 818 needs the suspension "tuned". Not just a simple alignment (toe, camber). For best performance, have corner weights adjusted and maximize caster.

With all spacers in, my tuner said the Baer kit was 1/8" too short, but we called it good enough. This was determined by exercising the suspension while on his fancy *** alignment rack.

I went with 1.5 degrees negative camber all around. For a street car, I think it's pretty good. But for a track car, I'd like to up it to 2.5 to 3.5 degrees all around.
