The Better Bilstein Ebay Coilover Thread
#84
The thrust bearings on the spring perches are a must on cars that run front struts where the shock rotates as you steer and the top hat is stationary, it probably helps keep everithing working without much bind as the suspention travels and makes it easy to adjust ride height without fighting the spring, but I doubt that it has a big overall impact.

The thrust bearing is there to prevent torsional loads caused when one perch is rotated relative to the other, such as when steering with a strut type suspension or rotating the perch. The only time our perches will twist is when the ride height is adjusted, and as long as you take the load off the perch when you do it, you're not going to twist the spring.
So we don't really need the torrington bearings, they're more of a strut thing. The spring isolators could potentially be beneficial, but I've seen several people say that they've ran without them with no issue and no one say they've ran without them and experienced scraping sounds during suspension compression. I assume this means that on the scale of the springs we typically use, friction between the spring and the perch is enough to cancel out any twisting caused by torsional stress on the compressed spring.
I'm not sure all of that actually made any sense, but it seems a shame to delete it after spending the time to type it out on my phone. Take it as you will.

Maybe this can show how the bearings will benefit by keeping the spring end from binding on the aluminum perch.
It's a company advertisement but does a good job of showing what happens to the end of a coil spring when you compress it.
I imagine running Swift or Energy isolators can accomplish the same thing. Or nothing... whatever does it for you.

Thrust bearings or plastic isolators would help accomplish this.
Right?

Will your lap times drop because you have bearings under the springs?
Highly unlikely.
Will your swagger increase when people see them (and helper springs for that matter) when they peer into your wheel wells?
Most likely.
Save the $$$ and put it towards something that will show bigger gains in your lap times... like better tires.
Or. Pimp out your poverty shocks and post pics all over CR.

If they're bound, they won't twist. But I'm not saying it's a bad idea to use thrust bearings. I'm just not convinced that they're necessary (all reports seem to indicate otherwise), and by the time you add up all the thrust bearings and spring isolators and spherical mounts and helper springs and $30/corner bumpstops and other cool **** that it would be awesome to have, you're squarely in "should have gotten a revalve instead" territory. And if you pay for a revalve as well, you're creeping into "should have just bought Xidas and been done with it" territory. What's the fascination with spending more money than necessary on something that's interesting because it's comparatively cheap?

Well... whether you revalve or not, you're still going to be using the $18/corner bumpstops that we're using.
But if you could point me in the direction of some super pimptastic $30/corner bumpstops, that'd be awesome.
I'm unsure what sort of logic fallacy shows that a revalve makes the other fun toys un-useful.

I only paid $48 shipped per set of four, but I bought 14 of them: One for the top AND bottom of each spring, one behind each brake disk, one behind my steering wheel, and one for the bottom of my cup-holder. My slushy spins like a disco-ball when I'm doing madd skidds down the mountain passes.

10/10, would read again.
