i know its possible but im wondering if there is something that im not aware off if i mount them upside down?
the reson why i want to do this modd is that ill get the weight from the dampers closer to the ground if they ar mounted upside down. also im experiencing that the rear dampers already have begun to leak oil, and i dont want to replace inside orings all the time. so can you tell me why i shouldt mount the dampers udpside down?
i run on a carpet offroad track, the same as kant76

It means the shock weight is normally over the main chassis, so its weight is added to the suspension reaction. When you put the body out on the arms, that weight is shifted toward the arms that aren't included in the suspension reaction.

Are you using the upgrade metal versions? They don't leak as easily and are much simpler to rebuild.

and yes im using xray alu versions and the rear ones are already leaking oil so that after 40min run time ive got to put in new oil.
ive had them for about 1? month now so i was very surprised to se them leaking so fast.
should i buy new orings ore will it help to put in thicker oil and go to 4hole pistons in the dampers?

The o-rings are easy to replace. If you want a racing tip, use AE green slime on the seals/o-rings. It increases the o-ring life.

Are you sure its not through the top? When I have leaked oil, its usually I overtightened the top and damaged the diaphragm seal. Also, make sure your bleeding the shocks before tightening as you could otherwise have too much internal pressure that will make the o-rings last that much less.

when you say make sure you bleed the shocks before tightening the cap what do you mean? im doing my shocks as pr the instrucktions and push up the piston before tightening the cap and my shockmembranes are fine they do not get damaged becasue i use limiters. thanks for your help and ill try that tip with the green slime :)

it would be very nice if someone would take their time to make a video off how to proper fill oil in the shocks because there are so many people who say its better to do it one way ore another.. so it would be nice to have one of you guys make up a video off how to :)

I thought you mounted them upside down to prevent the oil leaking. :roll:

i havent mounted them upside down yet, and wanted to ask here before i did it. it was my plan to do so to prevent as mouch oil spill as there is now when they are mounted the right way.

replace the orings and lube them up withe the oring lube I have with me always. I can make a movie with my way of building the schoks but you have already seen it like a trillion times on the track. you do build them the right way but it takes years of pracice to get them 100 % perfect every time. the main reason why your schoks are leaking are the lag of maintanance on your car. normaly I rebuild my shoks and lube the orings the day b4 we go to the track.
