If the suspension in your RX-7 looks anything like that of a Miata, your
stock setup is a coil-over type suspension. The common usage for
"coil-over" usually denotes a setup on which the vehicle's ride height can
be adjusted by raising or lowering the lower spring perch.
But going by the strictest definition, the stock spring/shock setup on a
Miata (and your RX-7, if it is similar) qualifies as a coil-over suspension,
as would a typical MacPherson/Chapman strut suspension. The way I read the
rule, I could legally add a coil-over setup from, say, Ground Control or
Truechoice, and still be legal in SP, although for me this isn't an issue
yet.
Hope this helps!
