Help: DSP and FSP classing anomaly

["Cliff Loh" <cliff_loh@infoserve.net>]

Mercury Tracer 16V in DSP
Ford Escort GT in FSP

While I can see the old 1.9L Escort GT being in FSP, why are the newer
ones (like Kurt Spitzner's ST car) in FSP when they are essentially
the same mechanically as the Tracer?  Should they not be in the same
class?

I don't know a whole lot about these cars so someone help me out
please.  It's an inquiry from a
local competitor.

thanks,
