Hello,
I figured it would not be a bad idea to start this type of thread for rules and what we can do to these cars to get them in GT-2.
We have an IMSA 997.1 that we are converting and have been seeing all kinds of stuff come up that HAS to be changed to classify the car properly.

The requirements I have come across so far are
Windshield clips 2 bottom 3 top
Rear window straps 2
Remove door windows and install left side net
Right side net recommended.

please any comments of know rules or modifications are welcome

 

just found this little piece of info in the GRC.
Not sure how I feel about this.

Glass and/or plastic headlights, front parking lights, front signal lights, lenses, and bulbs shall be
removed. Headlight openings shall be covered with a wire mesh screen or panel having the same
contour as the original lens, mounted so that the headlight bezel/rim remains in place, maintaining
the standard appearance of the Production automobile. Side marker light assemblies shall be
removed and the resulting openings covered with a plate whose dimensions do not exceed those
of the original parts; side marker lights that are an integral part of the taillight assembly cannot be
removed.
