Phillip at Mackin Industries (distributor for Volk, Proj Mu, ARC, Gram Lights, etc) recently sent these images of the Super GT Green Tec/Kumho Lexus IS350, which is of course sponsored by Project Mu brakes.
The car is fielded by Team Takeuchi and is driven by Takuya Kurosawa and Takuto Iguchi. The car and team haven't been doing so well this season, but the car is new and there is a learning curve to go against the Z and MR-S in the GT300 class, both of which are proven platforms. The IS350 seems to have replaced the Celica in Super GT racing, as the WedsSport team uses one as well. This IS350 is V8-powered (and not the V8 out of the IS-F), has some obviously non-stock aero and features massive suspension changes. Not much of the production car still remains.
