A few more morsels of info. from Speedhunters' review of TAS...
Time to shift our TAS coverage to Toyota, one manufacturer that has won back the respect of car enthusiasts since the announcement of the FT-86 in fall last year. To everyone's surprise Toyota's new tuning outfit, G's, created a turbocharged version of the new
hachiroku, leaving most stunned at just how damn hot this car can look dressed up with some tasty carbon parts. The G Sports Concept gets a more chiseled front bumper with a carbon fiber contoured central air damn to help convey air straight to the intercooler. The carbon fiber hood sports a pair of symmetrical air outlets to help keep the EJ20 nice and cool while the lights gain an Audi-like top LED strip for added meanness!
Carbon fiber is also used for the side skirts and the rear diffuser not to mention the rear spoiler, which is actually designed just like a Toyota F1 front spoiler!
The front fenders have been widened and now also feature a vertical air outlet. The wheels are of a more lightweight construction and are shod with one of the hottest performance tire out there, the Bridgestone Potenza RE-11 fitted in 245/40/ZR19 size up front and massive 275/30/ZR19 for the rears. Ride height doesn't look to have been lowered much compared to the Tokyo Motorshow concept but if you look closely enough you will notice that the front calipers, now painted in red, have moved to a behind-axle position and the rears to a front of axle position. Not sure if there are any benefits but if I had to guess I would say that either the hub design or the suspension layout has changed from the initial concept.
