Thrust bearings are not doing the same as the Hyperco perches. A thrust bearing only allows for spinning, not bending loads.
From the Hyperco site:
Notice it says tilt - something a thrust bearing does not do. The tilting is the most important thing here. Take a spring (little) and put it on your desk, then compress it with one finger. Notice it doesn't spin, but rather squirmes around.
From the Hyperco site:
By precise shaping of the sealing wall of both the perch and cylinder body, the perch can freely tilt as needed to evenly distribute the load of the spring.

When you compress a coil spring and the ends are constrained, the torque through the coils creates a bending force on the spring. I was told that up to 30% of the total damping has come from the friction at the shock seal when not controlled. Hyperco perches do the same at a much higher price.

...just read through this thread and I saw a few using these without the hardended top/bottom races. I would think the loads on the little rollers combined with the slight movement they'd have will wear grooves into the aluminum.

Is this on a sedan or a "real" race car with inboard suspension? On a sedan, it's as simple as using a helper spring to keep tension in the system at droop.

I used them on a set of ST44's I just did for a 355 Challenge:

It surprises me that I had never known about this problem until yesterday when I read Sunday Drivers thread. Then today, I get my latest copy of Grassroots Motorsports, and they have a product review of a company, sealsit.com, that sells them.
I can't use them because my car runs in SSC. But, I could probably run them and not get caught, because, if I make it into the top 5 at the Runnoffs, you can be sure that a meteor has hit Topeka on Oct. 11, or maybe even a hurricane.
