alright, i used to have a set of Koni and it screwed up so i got a set of BuddyClub RSD last week..when i bought it i didnt really focused on the shock itself, my attraction goes to the turbined B18CR EK next to my car.. so anyways, i went thru my car and have a look thru with the suspension today and find out the upper side of the shock is umm.. the upper mount is from my old koni.. or if its a stock item(i forgot how the stock one looks alike). i have completely no idea.

so.. does it affect performance at all? or im totally wrong about this topic at the first time?
thx for any inputs..
(or the upper mounts is actually the optional pillowball mount that i dont need?)
