[48Spoons]

F. Addition of spoilers, splitters, rear wings, bumper covers, valances, side
skirts, and non-functional sccops/vents is allowed provided that either:
1. It is a production part which is standard or optional equipment of a
US model of the vehicle. (“Model” is defined in Section 12.)
2. It is listed in the vehicle manufacturer’s US accessory catalog for that
vehicle for normal highway use. This does not allow for parts sold
through a manufacturer’s performance catalog (e.g., Ford Racing,
82 — 2015 SCCA® National Solo® Rules
14. Street Touring®
HPD, Mazdaspeed, Mopar Performance, Mugen, NISMO, SPT, TRD,
etc).
Parts must be installed as directed by the manufacturer. Exact
replicas,including weight, from alternate sources are also permitted.

Should be able ot under that rule as long as there aren't any special things that go with the install (I doubt there are). For example I know any S2K can run the CR front lip since its just glues on or whatever, but can't run the CR wing due to the trunk bracing that is part of it.
