02 / Why it's different

For wide-body programs.

GT4 is the wheel we build wide-body programs around. Deep enough to fill a 4" fender flare, light enough to keep track times honest. The flagship of the forged line.

  1. 01

    Unbox & inspect

    Every part QC-checked and serial-tagged before it ships. Verify fitment against the OEM body before drilling anything.

  2. 02

    Dry-fit & align

    Tape the part in place, walk around the car, eyeball the panel gap. Adjust before committing the adhesive.

  3. 03

    Bolt down & cure

    Torque to spec sheet, peel the VHB liner, press for 30 seconds per zone.
