Any problems mounting the RS 5000 shocks with the canister on top?

Thanks.

my brothers are upside down, and have been for a while without any problems.

I have been running mine upside down for years. I have run them right side up, and up side down, with absolutely no difference in performance.
I currently run them upside down because they dont hit my calipers in that position, No problems at all.

I run mine canister up they work fine keeps em from getting bashed up I think, I see no problem <IMG SRC="smilies/skull.gif" border="0">

Most cars run shocks with the can down, but most race trucks run with the can up because that's the only way to mount external reservoir shocks. So what is upside down is sort of a point of view.
