CRC is about to revolutionize 12th scale building when it releases its new front end. if you search through rc.50.com youll find pics. No more black magic (my specialty-ho hum) to get a perfect front end everytime.
some highlights include super fast and easy camber adjust with pillow ball, fast caster adjustments and no more shims on the kingpins. YOu adjust spring tension (preload or no preload) with a hex driver. Very hard to build it wrong (ie. binding). Ride height adjustment will be enough to run a rim with felt on it to a full size uncut tire. Steering arm (spindle) is now outside of the rim.
Also-with the flip of a part-you can go from unheard of caster to the caster we run now as well as choosing between 0,5 and 10 deg mounts.
