VTT “1.3” Drag Kit

BMW G8X Platform (G80 / G82 / G81 / G83)

VTT is proud to introduce our “1.3” Drag Kit for the BMW G8X platform.

This is a complete rear conversion package for AWD or RWD G8X vehicles looking to maximize traction at the drag strip.

On AWD (xDrive) vehicles, this setup virtually guarantees a 1.3-second or better 60-foot, provided the vehicle is properly tuned and launched. For RWD cars, this kit is essential to fully utilize available power and improve consistency.

Install it once — and beat your previous best ET.

Complete 17” Rear Conversion

This package includes everything required to convert the rear of your G8X to a 17” slick setup, dramatically improving traction and weight transfer while expanding tire options.

Recommended Tire Options:

• Hoosier DBR 28×10.5×17

• Mickey Thompson ET Street R 305/45/17

Both recommended combinations are 28” tall.

xDrive Height Note (Very Important)

Both recommended tire combinations are 28” overall diameter.

On xDrive vehicles, front tire height must remain within 3% of rear height to avoid drivetrain issues.

Deviating beyond this threshold may cause mechanical problems.
