Famed aftermarket and motorsport specialist HKS has released a new video of the Toyota 86 race car it is working on to participate in the 2012 season of Japan's D1 Grand Prix production car drifting competition. The new clip shows the 86 being tested on the dyno.

As well as the motorsports version of the 86, which you should know by now is a sister model to the Scion FR-S and Subaru BRZ rear-wheel drive coupes, the Japanese company is also preparing a raft of tuning parts for the production model.

One of the most striking Honda CR-Z proposals at this year's edition of the Tokyo Auto Salon came from Japanese tuning firm Silk Blaze. The heavily modded concept model boasts a full body kit with a new front bumper and grille assembly, side skirts, a rear wing and a new rear bumper with additional air vents on top, plus a diffuser and three-exhaust pipe openings in the center. The tuned CR-Z rides on deep-dish 19-inch alloys wrapped in chunky 225/30 rubber.

Even more impressive is the beast that lurks under the hood as the tuner said the CR-Z concept model features a HKS supercharged version of the 1.5-liter four-banger delivering 271-horses (202.4 kW). No other details were given about the powertrain upgrades in the firm's spec sheet. You can gaze upon the rest of the pictures after the break.
