Ken Block Subaru STI TRAX
We've already told you about two Subaru show cars headed for SEMA - namely, the SPI-tuned WRX STI and the Legacy 2.5GT VIP -- but the Subaru WRX STI TRAX could safely be called the wildest one yet. In the spirit of the winter season and based on a concept idea by DC Shoes co-founder and rally driver Ken Block, the STI TRAX eschews its snow tires for a Mattracks 105M1-A1 rubber track system to ensure that Block is still able to get to the halfpipe with his snowboard no matter how much snow falls this year.
In order to complete the Mattracks conversion, the 2009 STI's drivetrain was dropped three inches and custom machined hubs were added. As could be expected from a Block creation, the STI's 2.5L H-4 engine was also given a little extra kick, with a Motec M800 ECU that bumps output to a sizeable 400 hp and 400 lb-ft of torque. A KAPS five-speed close-ratio dog-engagement gearbox was tossed in for good measure and EXE-TC Group N competition rally dampers were installed for more control when the going gets rough.
A host of standard rally car modifications add to the package, making this Snow Cat on steroids a serious winter toy. Starting life as a stock '09 STI, the interior was stripped and the body was seam-welded for additional strength and rigidity. A roll cage then went in, as did carbon/Kevlar Recaro SPA ProRacer competition seats, a HANS head and neck restraint system, carbon fiber door panels, and an onboard fire suppression system. Suffice it to say, the STI TRAX means business.
A Yakima FatCat 4 snowboard rack sits on the TRAX's roof and is filled with DC Shoes XFB-C snowboards. And if that isn't enough, a matching sleigh has been built to go along with the car. Now that's a sleigh ride we can get behind, especially with Block behind the wheel.
