You really should get out more.
If you're talking about pre-load spacers or spring adjusters, that's at least part of their purpose.

O-rings on the shaft outside would be a bump-stop, to limit compression travel. It is not something I have ever seen seriously used in RC although they are common in full-size motorsport.

Ideally, you should only use a bumpstop to stop the chassis from bottoming out over the biggest bumps and kerbs. If the car rides on the bumpstop in normal running, you will lose a huge amount of grip because the suspension will effectively run out of travel.

Another reason to run bumpstops is to stop the driveshafts from popping out or similar issues, I know that with my old, old HPI Pro3 I had to run quite a few o-rings on the shaft otherwise the driveshafts would pop out in crashes.

Hope that helps.

Sometimes I wonder why people spend so much time bashing and then others piling on. It's like a bunch of kids in the schoolyard.

They are for setting "preload" when you have your ride height set and no downtravel, duh!

yeah, this thread has gone downhill, sorry xraycer, clever name, welcome aboard.

I think all ol' Doc was doing was trying to do was prompt the kid to read the manuals and tech sheets that the xrays come with or is available on their website. Otherwise the kid comes here and he gets bombarded with a lot of contradictory information he's not sure where it comes from.

The only use I can think of is to add droop to a mini cooper. With the o rings.

I've used 'em for that (inside the shock body) and as bump stops (outside the shock body) on my bottom-happy DT-02 buggy.

basicly using a o ring on the shock shaft would limit the amount the shock travels up sort of a bump stop which would work with a very soft spring on high speed corners so the chassis will not scrape the racing surface.

sounds like a specific trick for certain conditions. I'd hop over the Paul L. thread in a very clear and specific manner.

my guess..... don't do it. stick with team setup sheets.

It's a little square kind of round thing used for numerous things like holding your batteries in and such.

The car should never run on the bump stops. As soon as the car hits the stop the suspension will become solid all of a sudden and you will lose heaps of grip.

You should only hit the bump stops momentarily, use them for protection when riding the kerbs or the biggest bumps, not in normal cornering.

If you want to run soft springs/lots of chassis roll but have problems with bottoming throughout the high speed corners, raise the ride height.
