The numbers are 53:47 front-to-rear weight distribution with a center of gravity sitting between a Cayman and a Cayman R (Cayman 482mm, GT-86 475mm, Cayman R 462mm and for scale a GT-R 495mm). Oh and it's almost 200 lbs lighter, 4 inches shorter, 30 inches wider and only .4 inches taller than a Cayman R as well.
