    JST Performance

  2. Street Car ET

    Focus ST Drag Racing
    driving to the track and running a fast time and driving back with no changes is going to be hard in an ST. i did just that in my first ST street car. it was a full bolt on 2015 ST on E30, nothing special at all, just Levels IC, Mbrp turbo back, green filter, plugs, and a custom e30 tune by me...

    COBB Tuning

    JST Performance
    The JST Performance Focus ST at Road Atlanta for its debut. car was detuned to only 301whp for testing purposes, and was actually probably making less than that in this video due to the heat and heatsoak of the day.

    Focus ST Drag Racing
