NissanRoadRacing.com The guy who made the custom housings (veilside180sx) runs that site, they have this stuff all over the site, In the suspension section they cover allot of this stuff like using 3000gt Bilstein inserts for the 240sx fronts, spherical bushings made to go into stock spindles, etc... All though directed towards road racing (very little if any talk of drifting) it is a good site to read trough if interested in putting together your own suspension pieces. I can't wait to get the race inserts for my car but the 240sx koni replacements are not that bad even when getting it low the big problem I had was the front like most people, but cutting down the strut tube and modifying the lower part of the the tube dropped it lower and still got to keep the stroke, And my wheels fit pretty nice offset wise so they strut mounting wasn't an issue for me.
