You're telling me, my city puts manhole covers in a road track... what a stupid fucking idea.I have the Tanabe NF210 lowering springs installed. I love the look and all but the main problem is my location. I live in NYC and the roads here SUCK @$$. Dont get me wrong the springs run great when the road is smooth and i love it but if you are in a area with pot holes and bumps it might not be to comfy to ride in. Sometimes im on the highway and i go over a bump with a loud bang and it would hit hard enough for my window wipers to turn on. I cringe everytime this happens lol. So im switching to the Nismo Suspension kit or the Tein or Tanabe Coilover from BoB at versaspeed.
