The Nismo suspension kit for the b12 has long been out of production. A couple of months ago Nissan Motorsprts USA was clearing out the last of them, so alot of us got a killer deal on them.
Greg Vogel at Mossy Nissan ([email protected]) was responsible for getting them to us. I think he may have one kit left. He was selling them for about $560 or so... the original price ran about $2,000. I havent installed mine yet but maybe John Nismo Driver has. Definately contact greg if you are interested in these kits... tell him i sent you.
