Appreciate the attempt at answering the question, however, the reference to the GCR is not applicable, or in other cases even the PCA rule book for that matter. The 944 Cup rules are fully self contained and what you need to know about the series is contained in the 944 Cup Rules. The Cup rules no longer make reference to PCA or SCCA Prep.
Rear coilovers are not permitted for Prep 2, but are allowed for Stock and Prep 1 .
A splitter is allowed in Stock and Prep 1, but not allowed for Prep 2 as the rules do not provide for anything other then the stock spolier.
