[AdeC]

AdeC pull the interior, you will want a lexan interior in your car.  If your glass is not in 4 individual pieces you will want to cut them so they are and remount.  This will release 2-5 grams from up high in the Porsche as it is one of the taller cars in the proxy.  Make sure your front tires ride lightly on your set up block, and your fronts ride as wide and out to the fender as it is also a narrow car for this proxy. This all said your car will probably out run my Porsche without the suggestions.  I also test on a sport track.  

The interior lasted about 20 seconds after I took that picture   . It was pulled straight afterwards and replaced with a universal lexan alternative saving about 6-7 grams! The glass is still stock but now pendle finally have the lexan alternative in stock I'm tempted to replace that too, although I'll see what savings can be made by trimming first
