E36 / E46 / Z4 rear swing arm (RTA) front mounts.
- 50% greater range for track adjustment
- Dual bolt pattern with standard or 15 mm improved anti-squat setting for increased grip under acceleration (eccentric bushings MRT-20023-3 must be used with this setting)
A higher anti squat angle (higher bolt hole) allows for more arm action in leaning the car backwards under acceleration, this provides more weight displacement and therefore more pressure on the rear wheels and less on the front wheels.
