Coilover, grinding Options

[Shigexile]

i know i asked this before but i still don't get it. In order to install coilovers you have to grind the struts right? Why? Arn't coilovers made so they fit our cars? It doesn't really matter but isn't there any coilovers out there that you don't have to grind the coilovers?
Whatever.
My main question is, on the KYB struts do i shave the circular part that is partly gold in color? or am i way off? I need your guy's knowledge or i can't install them or have anyone install them. HELP ME

my tein oilovers fit fine, complete bolt on. harsh aride during the break in period but other than that nothing really out of the ordinary.

are you talking about grinding the top of the struts to install ground controls? I did it but honestly its a really easy thing to do. takes about 5 minutes on a grinding wheel. also I don't see how they could avoid doing it, the top sticks out a little bit from factory and the coilover has to be tight around the strut

edit:

SilverCell94, long time no see. whats new with your ride?

my coilovers don't even fit around the struts (it fits halfway until this gold ring comes up and). There is only like a 1mm difference in diameter. i thinking because the struts and coilover is different brands so thats why the coilovers arn't fitting around the strruts. So do you think i should grind part of that?

pictures would help. but more than likely you need to grind the cap that holds the insert inside the strut
