No worries, I didn't know what KW2's were at first either. I forget if I'm allowed to post a link to KW's website, but just do a google search for:
KW Variant 2 Coilover Suspension it should be the first link that shows up in the search.
I think it's pretty bad a$$ too since you can kinda see the purple yellow coil-overs through my 19/20 Wheels. They are a really good suspension and well known as one of the better choices for performance and affordability compared to more expensive versions like Motons. I also don't track my car so I didn't need anything extreme, just wanted a pretty good suspension that lowered my car safely.
If you've been using Eibachs and like how low the car looks, than you do not want to go the original suspension route, trust me lol. My friend had Eibachs, but he didn't like the way the ride of the car was, and when he put his stock suspension back on the gap between the tires was a lot more noticeable, hence he referred to his car as a 4x4 lol. He eventually purchased lower profile Spring Caps to go along with the stock suspension to slightly lower the car again, but it wasn't lowered as much as with the Eibachs.
I don't have real small fingers, but with my stock suspension I was able to put 4 fingers between the gap where the tires are. Now after being lowered I can barely put 2 fingers. If I had Pirelli Tires, I could have lowered my car more, but with the 30 profile on the PS2s it was the safest to leave about an inch for the clearance with no rubbing.
Sorry I am kinda dumbfounded when it comes to abbrevs or maybe I just dont know the make. What are KW2s?...lol Also i do have the original suspension set up if I need to go that route although I would rather not go through all that mess right now. Probably stick with the Pirellis. Just feel I am paying more for the name then the tire. Although they are great a great running tire.
