My FUCAs are of that kind.
I'm basically looking for a set of tools to do reasonably accurate DIY alignments, with a twist that the tools need to have a way to adjust for non-level floors. The ones I linked should take some spacers, so that I could level them once and keep using after. But they are only rated up to 4000lbs.
An upgrade to the string method would also be a welcome one, since the latter gets annoying once you startmessing with camber (and as a result front/rear track widths are no longer fixed). So, if anyone has any leads on decent alignment tools that don't cost arm and leg, I'd love to hear those.
I guess I am overall saying, for example, after a race day (where I already know the current alignment specs),
—20 minutes to lift the vehicle for a coarse adjustment(including removing the rear wheels).
—5 minutes to drive around the block (or to the event location)
—10 minutes to re-measure
—20 minutes for final adjustments (including removing the rear wheels).
Thus, I am looking at about an hour for the whole process. I have even done the first round (20min) of coarse adjustments at the Supercharger, meaning I only need a half hour to polish after reaching the track or home.
For these alignment rigs, I would expect at least 15 minutes for setup and another 15 for tear-down, plus another 15-20 minutes for measuring and adjusting. Additionally, one would still need to test drive the vehicle to confirm the wheels are also correctly aligned relative to vehicle, and not just each other (i.e. confirming a straight steering wheel with no pulling). So, I am not seeing a lot of benefit, with two caveats:
1) if also deliberately adjusting caster, that would add a lot of time to the simpler iterative process, and it would be very difficult to get everything done in two rounds of adjustment (potentially meaning an extra couple 35-minute adjustment cycles).
2) similarly, my ~1-hour timeline assumes adjustments are complete after the second round. That was
definitely not the case the first few attempts, and still isn’t something I could guarantee this early in the game (especially for the rear).
