The KJT R&D Membership is for Stinger and G70 owners who push the platform: upgraded turbos, ethanol, water-meth, built drivetrains and aggressive calibrations. Your car joins our development network. You send us logs, dyno sheets and dragy results. We send you the newest calibrations first and back your drivetrain if something lets go.

Financial assistance toward engine or transmission replacement for approved failures while your membership is active
Free tune revisions and calibration updates as they are released
First access to beta ECU files before public release
Free or discounted KJT apparel and merch
Free entry to KJT hosted track events and private test sessions
