We stumbled across this Esses Racing listing for a unique Porsche 997 GT3 Cup while researching. Unfortunately the details are sparse but we know the iconic race car no longer has a flat-six. Instead there is a 7.0 L LS7 V8 sitting in back producing 590 hp and 522 lb-ft of torque. The car still retains the GT3 Cup six-speed sequential transaxle. The body features carbon fiber roof, bumpers, deck lid, and wing. While the interior has OMP seats, Momo steering wheel on a Rothsport quick release, and full roll cage.
