I had JOM temporarily and it was good for the money but made the upgrade to Bilstein B16 Pss9 and have to say JOM's will not compare with premium coilovers - you can't compare them. It has been a while since I made the change to bilstein b16 pss9 but I remember still the massive difference!
Driving in a straight line over imperfection you can actually feel the b16 pss9 coilovers working, in comparison the JOM felt like they were just along for the ride and did nothing. My coilovers are not made for comfort but the track and so even when I set the compression and rebound settings to soft it is still more harsh than oem, but the likes of the kw variant are renowned for their comfort. There's a lot that goes into the design of premium coilovers from the valving used to the spring rates. JOM are just for slamming.
