Adjustable Rear Upper Control Arm (A-RUCA) for rear camber adjustment

2tCornot2tC,
Thank you for doing this. It's clear after looking at some of your other work that you pay attention to detail and have an excellent work ethic and I'm betting this isn't only because you've got a lot riding on (safety wise) these parts.
And thanks for the update!

The final setup...
I asked for 0.0 camber up front and 0.00 toe up front...these are both within manufacturer's specifications. I provided SPC bolts to do the fronts but this is only temporary until I get the TEINs. I also asked for -0.4 camber in the rear which is the minimum allowable. I also asked for a smaller toe (outside OEM range) of 0.02 toe in. Toyota specifies 0.04 as a minimum toe in the rear but I feel that that promotes too much under steer and too much scrub on the rear tires. The final sheet...
I posted my start point sheet here with the OEM RUCAs...

Thanks...
A significant improvement! But my answer is biased…and here is why. If you look at my start specs, you can see that my left rear had a -0.05 toe… that made it feel real loose on right handers. All off/on ramps are right handers in OH and IN. Any left handers are such long sweepers (they might as well be straights) that you just can’t tell on them. So, all of the ramps that you can gauge the handling on are all right handers. Since all of the weight transfers to the outside, the left side alignment determines your handling characteristics. It is now a very light handling, responsive car.

btw after u installed TRDs, how did u tighten shock and control arm bolts?
bolts B and C:
do u have a full car length ramp? is tightening them with just rear on the ramp ok? or does it have to be at ride height with proper weight distribution?

I just snug them down…about 5-ft-lbs. Then I dropped the car and got a long ½” drive torque wrench in there. If I recall correctly, I had to torque them twice…there was not enough stroke to get a final torque. Since I don’t have ramps, I did not use any…there is such a small weight transfer from the change in elevation that I would not worry about it. It will sure make the job significantly easier.

Got the wheels off to safety-wire the A-RUCAs...this is what they look like installed...here is the right rear...
This is the left rear...
Note that both of these arms are identical and take a look at how far each ball joint is exposed.

Anybody wanting to check out this car up close and personal will be able to at the Midwest Car Meet at Richmond Toyota/Scion on May 5th. Here is a link to the event...
