He was the quickest of the 6 drivers in qualifying, and consistently produced the fastest race laps during his 101⁄2 hour multiple stints behind the wheel.

He made his debut in the BTCC series behind the wheel of a BTC Racing Lexus IS200 at Brands Hatch on 24 September 2006, alongside then team-mate Darren Dowling.

[6] In October 2012, Stockton revealed he had purchased an incomplete NGTC Chevrolet Cruze from RML which he intended to finish and enter in the 2013 season under the BTC Racing banner.
