I recently bought some used kw coilovers but i couldnt find anyone running them. it's okay to have the rear perch at the top? I tried placing it at the bottom but the fitment was slightly loose. The perch fits perfect on the top, but I was wondering if it requires a plastic gasket in order to avoid metal to metal contact? I am currently experiencing some rattling issues when I am riding on rough pavements or making turns.

 

you have the perch upside down. You should contact KW on install info. They are pretty good about getting back to people. Its not only a danger to you running things the wrong way but every one else on the road also.
