Premier Motor Sports is a Kirkham Motor Sports dealer and finisher and has
developed a high quality component car based on the original 427SC chassis and
suspension with a fiberglass body. The original chassis design has been kept while
increasing the strength and design of the front and rear structure for the larger aluminum
radiator and increased trunk room. Suspension has been modified from the original to
use late model Ford braking components, which are upgradeable to Wilwood. The
suspension will interchange with the original 427SC and vice-versa.
