Wheels would be the best idea; but I am out of time for that option. I know these things are not going to fall off; but the wobbly vibrations are going to drive me nuts.
I have a couple more tricks to try. Things my grandad taught me.
Anti-seize can be your friend, if used properly.

 

If you get in a real pinch too, you could always try the "airsoft BB balancing."

 

I hear the Airsoft system works great, and it keeps the brake dust off the wheels. That may be the best idea of all.

 

Update:
I took my whels off, and torqued the spacers myself. I started with 20 ft-lbs, then 60, then 100 ft-lbs.
Then tightened the wheels the same way, except only to 80 ft-lbs.

There is no more wobblies or vibrations. Nice and smooth.

These spacers are sensative to lug torque. No forgiveness.

The tire shops don't take the time to do it right.

I am happy once again.

Cheers! :-)

 

thats good to hear. I dont know how I dont have any vibe issues on mine but they are smooth.

 

No more worries then.

Take lots of pics in DV.

 

Glad you got it figured out, I was going to recommend snugging them with a star patern in the air, having someone hold the brake while you pretorque them with maybe 45lb. in the air, star pattern of course, lowering the vehicle so the wheels barely touch the ground and torquing them, than lowering the jacks all the way and torquing them again. Non-hubcentric setups can be touchy

 

Returned from Death Valley trip. We drove almost 3000 miles. There are slight vibrations at 55mph & 75mph. Nothing terrible. The spacers held up to 60 miles of bad washboard roads. I never had to do any retorquing or adjustments.

 

New update:
As you all know, these suspensions work as a system. If you install large tires, you need more room. A lift and trimming is in order. Then you need more room behind the tire; so spacers or wheels are in order.

Two problems crop up. With the lift, and alignment, you lose some caster angle. With a low caster angle, the wheels are more likely to shimmy. I did not notice any shimmy problems, after my lift, until I installed the 1" wheel spacers. The lack of caster angle, magnifies little issues, that may not have been a problem before. I have to tighten the spacers and wheels very meticulously, or I have terrible shimmy problems.

So; the next quest will be to modify the alignment; to add in a little more caster, at the expense of some camber. I can't go to far with this, or else I will start to get an effect similar to bump-steer (like driving a Twin-I-Beam Ford). If this helps; but does not solve the problem, it will be time for a now pair of UCA's. The aftermarket UCA's have more caster built into their geometry (moves upper balljoint back a bit). --OR-- I hear people mentioning some special Toyota parts to solve alignment problems. I will have to look into those also.
