Why do you need one?

This top mount allows you to adjust caster (wheel position) and camber.
Caster adjustment is important especially on track cars where extra caster can be beneficial, especially on non-M cars such as E36 and E46.
Conversely on a E30 with E36/E46 spindles this top mount can be used to reduce caster to a suitable range.
Top mounts allow caster/camber adjustment up to Gr.A and/or STW specification on their specific chassies.
Pillowball design is 100% solid without any flex. Recommended for track and drift use.

Does it fit my car?

These top mounts can be used with most common coilovers with 14mm or 16mm shaft diameter. See available variations:

Top mount style:
