Stanley was super helpful and builds a great product! I highly recommend GBox Inc for your transmission needs. He even took time to go over tire size recommendations as mine are to wide to create proper 200deg temperature at the tires (which is required for good traction). Could not be happier with these guys!

purchased a rebuilt transmission for a Porsche Boxster in the past-My client raced it for four years before selling the car. It performed as a trainer car before he committed to a 997. Never did it not deliver as promised! Very pleased and would recommend them for their products.
