The team at Sharkwerks just fit this 997 GT3RS with a set of 19-inch Forgeline one piece forged monoblock GT1 wheels finished in the Graphite powder coat. Though the GT1 wheel was primarily engineered for fatigue strength and deflection stiffness, the Sharkwerks team reports a mass reduction of almost 4.5 lbs per corner, in the front, and almost 9 lbs per corner, in the rear, compared to the stock Porsche wheels!
