Default Rear suspension falling out

Hello,
yesterday i took my freshly built x16xe mini to the track for some fun.
It was fun
But the right rear wheel suspension fell apart, track has mostly right corners so thats probably why that one was affected.
Is there any rebound buffers or something to use to keep this from happening?
Car is running on hilos and its not that low even. But when i jack it up, the suspension arm comes so low that i have to hold the pieces in place when i jack it down again. Can this be fixed with a shorter damper?.. i got brand new kyb's so i dont want to replace them unless i really have to.

Only heard of this problem on Mini's that have had the standard trumpet cut to lower the car. Usually with the HiLo wound to a normal ride height this issue doesn't occur.

Is it possible to remove the shocker and measure it's maximum length. Compare that to a standard shocker. Should be no longer.

The only other thing I can think of is the rubber donut is old and compressed. The rubber goes hard over time and doesn't expand and retract as a new one would.

Hello, Thanks for answer. I measured it in place, and it is about 360 mm from mount to mount.
Rubber are new, as everything else on the car...
It is lowered of course, but i can still get almost 3 fingers between the wheel and the arch, running 165/70-10".

Measured to the lip of the sill, is 250 mm.

Lowered shocks have a similar to standard compressed length, but quite a lot shorter extended max length for exactly this reason. I have a data table somewhere, let me look.

Yes, i saw on minisport website that it differs around 30 mm.
Mine are actually about 380 long. Seems that i have to replace them......... but... what ride height is standard then? If i set these so that they dont fall out, the car will be so high that it cant be driven.

So i just found my shocks info on minispares:
http://www.minispares.com/product/Cl...aspx|Back%20to

They are 362 mm... And they have lowered versions of different shocks, that are 350 mm and one 365 mm... so i guess these should be fine, anyways, 12 mm shorter would not help me with my problem... hmm, i dont know what to do now.

I remember seeing once a leather type strap that jpined the top and bottom mounting points decreasing extension, was possibly an mg of some sort.but could have been fitted to a mini, my memory is terrible.

Not your typical heated leather seated track day car but it does have heated leather!

How old and squashed are you rubber donuts? I was running my 10" wheel car so low you could barely fit one finger between the tyre and arch and didn't have the problem you mention. I have lowered avo on that

i fitted a spring (a series oil pressure spring cut in half) inside the hi-lo, a bit will need trimming off the end of the rod to allow room for the spring. Put the spring in and the rod, compress the spring fully and measure how much needs removing to allow the rod to slide in fully then ad 1-2mm to this and cut that amount off.
The spring keeps pressure on the cone etc when in droop and holds everything in position

If your cones are new then they take ages to settle, you wonít be able to set your ride height properly until thatís settled and itíll lower itself when it does and can hopefully wind out the Hilo to get the ride height you want and prevent it from dropping out.
This means youíll have to have a taller ride height for now or you can do what Gaz has said, they can take months to settle sometimes.

That spring idea looks good, i think i Will try that! And the comes have been on for a month or two, actually longer, but only drived it for about 800 km with them on, so they are going to settle a bit more i guess.
A strap to prevent it would also work, but i dont see any good way to mount it, to clear the wheel and so. Any idea here?

Heard about people using a strap on shock mounts to limit the drop and other people have used a larger rebound buffer to restrict the radius arm movement.

Don't think your shock absorber is working!
It works up and down,
And make Shure your swing arm nuts are holding the arm,
It will fall down slowly but it should not fall that fast if it's held by big washers,
