Consistent, repeatable, accurate rear alignment adjustment:
You love the wonderful driving dynamics of your semi-trailing arm BMW, but you hate the fact you have no control over your camber or caster adjustment!
...Maybe you have tried 'Eccentric Bushings' in the past but have come to realize that they cause more trouble then they are worth; loosing adjustment at crucial times.
...Your lowering springs or coilovers get your stance right but you are stuck
with too-much-camber!
...You track or drive your BMW hard and have found that without proper rear alignment, your BMW will never perform at it's peak.
Extensive BMW experience here at VAC Motorsports gives you our rear sub-frame modification service: By sending us your sub-frame (or by using a core we provide) you will gain simple, repeatable camber and caster adjustment independent of your rear ride
height letting you and your BMW obtain the performance you would have otherwise never obtained. We have offered this service for over 20 years and do a fantastic job.
This modification does not adversely affect the ride quality or reliability of your BMW. Its also very simple to adjust requiring no special tools; it's just the same as aligning any traditional late model vehicle.
Save tires and improve handling dramaticaly.
