How important is rake during bump steer set up? It's been a while since I did it, so I don't remember the prep details. And my notes don't mention rake as a critical parameter, but it would seem to me that it might be important, no?
The Long Acre instructions say to place the frame on blocks at "ride height" and jack the A-arm to where the hub height is for normal set up conditions (w/ driver/fuel weight etc). It could be argued that that means at all 4 corners to get the rake right, but it doesn't specifically say that. My first thought was that the point was to get the hub height correct relative to the frame height for one corner at a time.
Reason I ask is, I was going to leave the car on the stands (frame level) for convenience. I would then take that (stand height) difference from ride height into account when jacking up the A-arm to have the correct hub height relative to the frame height. But that convenience doesnt' simulate the rake. I guess I could mess around with wedge shims, but my Lazy Man's credentials might be forfeited.
I run at 1 to 1-1/8" rake. How critical to bump steer set up is having the car on the rake?
