PCA GTC Rules Change - Parts Substitution
GTC Parts Substitutions Effective Immediately from PCA
GTC Parts Substitutions:
Here are some approved parts substitutions for some of the GTC classes. If you race one of these cars, please share this with your shop:
1) Some additional 996 Cup (GTC3) parts are no longer available from Porsche Motorsports. The following substitutions are allowed for this model:
Headers, if damaged beyond repair, may be replaced with a) stock 996 GT3 or 997 Cup headers, modified to mate with an allowed exhaust system after the collector, or b) a fabricated replica of the same tube OD and ID and shape as the original Cup part made of mild steel or stainless.
If the bushings are worn out in the shifter console, bushings of any material may be fabricated to replace the original bushings, or the Function First Shift Right 996 retrofit kit may be installed. This allowance may not include a "short shift" function.
Shift cables are free as long as they are of stock length.
The urethane front bumper may be replaced with an accurate fiberglass or flexible material replica (note - this does not allow use of carbon fiber).
2) The 2010-2013 997 Cup (GTC5) tubs are NLA, and modified 2006-2009 (GTC4) tubs may be substituted.
3) The 2014-2016 991 Cup (GTC6) tubs are NLA, and modified 2017 Cup (GTC7) tubs may be substituted.

The goal of the GTC classes is to Race WHAT WAS DELIVERED FROM PORSCHE. So on the shifter, they are trying to accommodate using as much of the factory shifter as possible, without adding an advantage like short throw shifter. As bushings can now be of any material and wholesale parts can be substituted, could a Numeric Shifter be used as long as setup without and short shift function? I cant say for sure.
