You dont need the N1 Spec unless you want some serious coilovers. They come in two specs and cost about $1500 from <a href="http://www.i-m-racing.com" target='_blank'>http://www.i-m-racing.com</a>. Type S models ( height adjustment, helper spring) and Type R models ( 13 way ride adjust,height adjust.) Pillow upper mounts optional. This is for the Nicer model. I think the WS models are adjustible but not as much as the N1 model. Find out from Shawn @ Enjuku Racing.
You wont need the pillow mounts. If you look at the picture of my coilovers the top of the coilover is a purple plate that mounts to the body of your car, it just allows for more driver feedback.
