I bought the 93-96 Supra LCA's and had them installed without any fitment issues, and afterwards had an alignment done without any issues either. The good news is that everything fits as it should with a cost savings of over $1,000.00. Now for the bad news. There are only two negative side-effects I've noticed after 1-week of driving with the new LCA's. They are:
1. The stiffness of the new LCA's has changed how the car rides. Specifically, when going over bumps in the road, I can feel way more vibration than before. I can hear and feel every reflector I drive over when I'm changing lanes and it only gets worse with pot-holes. However, it's not clear whether this would have also been the case with new Lexus LCA's also. The new rubber on the Supra bushings and ball-joints is said to be stiffer than that of a Lexus, so I would imagine that it would at least have been slightly smoother with Lexus LCA's. Still worth the cost savings to me however.
2. The ride height of the front end appears to be slightly higher. Again, it's not clear whether this would also have been the case with new Lexus LCA's since the rubber on the old ball-joints had deteriorated and may have compressed under the the weight of the front end. The difference in height that I'm seeing now may actually be the correct ride height that the vehicle would have had when it was new. Still it looks odd to me since I'm not used to it.
Other than those two things, I'm satisfied with the Supra LCA's since it has definitely improved the handling of the vehicle and saved a significant amount of money in the process. Pics below:
Side-by-side comparison. LEFT LCA = Stock Lexus LCA (I'm told it's aluminum, hence the ridiculous price) RIGHT LCA = 93-96 Supra LCA (Supposedly cast-iron and heavier than stock LCA's)
Another side-by-side. The only noticeable differences are that the tab sticking out near the rear bushing, and the small lip surrounding the Lexus LCA rear bushing, are both missing on the Supra LCA. Not sure what they were for, but it's doubtful they make much of a difference.
Here you can see the difference in the worn-out ball joint vs. the new joint on the Supra LCA. This is probably why the vehicle has a slightly higher height on the front end now.
Finally, this is the Supra LCA installed on my Lexus. It does indeed fit.

Hopefully this thread will put the issue to rest, again, even though there are multiple threads stating that the Supra Arms work... and the differences... but hey - there's still a few that seem to be overly cautious/paranoid.
Hi, I have a comment on the ride height and stiffness. A mechanic buddy of mine told me that most bushings like that are meant to have a little spring to them but not too much, that is because the center does not rotate so the rubber around the center bushing acts like a spring. so if you tighten the bushings in place with the car in the air then when the car is on the ground the bushing is being stressed and trying to resist (if that makes sense).
To remedy this keep the bolts that hold the CA loose and jack up the control arm end until it is about where it should be when the car is on the ground then tighten the bolts, that way when the car is on the ground the coil springs are providing the preload and not the rubber bushing.
I first encountered this when doing front ball joints on one side of a ford explorer (I know you SHOULD do both sides but the owner was cheap) and when I was done it sat totally leaned to one side (the new side higher). I tightened it like this and it sat flat again, I've been doing them like that ever since.
