chassis was further stiffened by adding two more support braces to the frame. An optional big brake kit by TRD is also available on the X-Runner; which consists of a 332 mm slotted rotor and 4 piston caliper. The BBK (big brake kit) was designed by StopTech. To further its track and sport appeal, TRD also offered a dealer-installed and warrantied roots-style supercharger which raised the power from and the torque was raised from . A factory TRD composite spoiler was also an option but originals are rare. The X-Runner comes only with an Aisin RA60 6-speed manual transmission. Production numbers are unknown but it is believed roughly 3,000 X-runners were made each model year. Production The second generation Tacomas were assembled in Tijuana, Mexico and Fremont, California while the plastic/composite beds were all built in Mexico. After the bankruptcy of GM, GM ended its joint venture with Toyota. Toyota, needing additional production volume at its Texas and Mississippi plants, ended Corolla and Tacoma production at the Fremont plant. In 2010 all Tacoma production was moved to Toyota's Texas plant in San Antonio alongside the Tundra. This brought a total of approximately 1,000 new jobs to San Antonio. Safety and structural integrity The Tacoma comes standard with anti-lock brakes, brake assist, and electronic brakeforce distribution. For 2008, a rollover sensor was added which would deploy the side curtain airbags in the event of rollover in Tacomas equipped with the optional side airbags. Beginning with the 2009 model year, all Tacomas feature Toyota's Star Safety System which added Vehicle Stability Control and traction control. Front row side torso airbags and side curtain airbags for both rows also become standard as well as active head restraints. Given the smaller size of pickup trucks in the Tacoma's category, crash testing for these sized trucks lags with how well most full size trucks perform. However, in an Insurance Institute for Highway Safety (IIHS) test of the Tacoma and other small trucks, only the side airbag equipped Tacoma received the highest overall rating of "Good" in the side impact test. The Tacoma also is rated "Good" in the frontal offset crash test. In 2009 with the active head restraints the Tacoma is given the IIHS's Top Safety Pick award. Third generation (N300; 2015) The new Tacoma was officially unveiled at the January 2015 North American International Auto Show with United States sales launch following on
