More info: Talking to Cody Walker, he mentioned an insider telling him that the new Supra is several seconds faster than the Z4 around the Ring. He noted it will be quite the controversy when both cars are on the roads for the masses. This could be true since the Supra is a hard top coupe and probably lighter. But he commended the Toyota engineers for their work on the suspension as being the main element for the quicker track time. He told me Toyota had their hands on most of the design, but had to use BMW parts and drive-train to even make this car a reality. Plus they may have had input on the B58 development back in 2012. He says the new Supra is growing on him. He's hardcore classic JDM guy like his bro.
