First post, long time lurker.

Are you talking about a new rule?

Port installed options are legal in Street. This is what caused the FRS/BRZ dilemma with the TRD option suspension. Same with the protested Mini in STX with a boost altering option (I heard at least).

Section 12: "An item of standard or optional equipment that could have been ordered with the car, installed on the factory production line, and delivered through a dealer in the United States. Port-installed options provided by the manufacturer are considered to be the same as those installed on the factory production line. Dealer-installed options or deletions (except as required by factory directives), no matter how common or what their origin, are not included in this definition. This definition does not allow the updating or backdating of parts."

As the rule is currently written, any/all port installed options are considered standard parts and are therefore legal in Street regardless of their performance impact. If the coilovers were port installed (I think they are dealer installed), they would be legal.

This specific rule is an advantage imported vehicles have over domestics.
