Well there's your problem. If you " force" them on, then they will bottom out before you hit the rebound stops. Possible to break the damper mounting pin.

Dampers should have enough travel to cope with fully closed to fully open, so should not be difficult.
The post about Gmax dampers before seemed that they were incorrect. I gave this info before , still stands...

Std front damper open 330 mm, closed length 210mm, stroke 140mm
Rears open 380 mm, closed 240, stroke 140mm
Hope this helps.
Sports pack different
Front 425/333 stroke 92
Rear 380/250 stroke 130

Hope this helps

 

gmax 25% uprated dampers....

KYB standard replacement for original factory spec dampers...

I don't understand what point you are making?
Uprating damping force has nothing to do with bump to rebound travel. Nor open and closed lengths.
Short dampers mean using the damper itself as the rebound stop. Mini front suspension is designed to use the subframe rebound buffer as the stop, not the damper mountings.
As for the links, Minsport does not quote the travels on either. They do say KYB I standard so the travel implied would be standard.

I checked with Mini Spares this morning and they quoted the figures below for standard dampers and mine match those figures. They told me that the GMax are only available in standard format. So now I'm really confused as I still need at least another 10mm

 

Front

End to end
opens approx 33 , closed approx 25.5

Pin center to pin center
opens approx 30.2,closed approx 22.5
--------------------------------------------------------------
Rear

End to end
opens approx 40, closed approx 30

Pin center to pin center (between of 2 top bush)
opens approx 35, closed approx 24.5

ALL READINGS ARE IN CM's

I think the issue is the new cones! 

 

See if you can measure the pin to pin distance with the wheels on the ground. I am sure it will be within the fully open length of the dampners.

The wheels are on the ground.

 

I got the following figures for the KYB ones...

 

442001
Fully open length from pin centres is 324mm and closed length is 210mm.

442002
Fully open length from pin centres is 3680mm and closed length is 222mm.
 

And the front ones are 22mm wider than the GMax ones I have by the looks of it.

 

Cheers, Paul.

Sorry Paul i miss read your previous post. i didnt realise youngad already measured the gap on the car.

given your measurements i Personally I don't see an issue fitting the dampners. Your new cones will settle in a month or so!

On really lowered minis the rear dampner does act (wrongly or rightly) as a sort of check strap.

[PaulColeman]

Is it possible to get the brackets which the top of the damper mounts on the wrong way round? I'm still trying to figure out why the dampers don't fit and I'm getting to the point of returning them.

 

Thanks, Paul.

There was a post about this "Does this look right" where I commented and was told I didn't know what I was talking about - any idea where it went?

[Captain Mainwaring]

They are shortened dampers

Second post in a week from someone whos been sold shortened dampers instead of normal ones

 

What happened to that post with photos of a similar issue?

[jaydee]

Nah mate that was not the same problem, that post was about normal length KYB dampers, here they're talking about some G-MAX dampers which are about 2cm shorter hence the problem
