ENGINEERING BMW RACING PERFORMANCE
BMW has manufactured thousands
of cars and each car differs to a degree and no two are the same.
This is called manufacturers tolerance.
With age the
chassis strut towers migrate/change location after years of use, or
are deformed due to an accident that has caused non-repairable
damage to the subframe. In some cases this can cause assembly
problems for the front strut installers.
The 3 piece adjustable strut
bars are easier to install but not as rigid or structurally sound.

Put the car on a flat surface,
set rear brake, chock rear wheels.
Remove the three front strut top nuts
using a 13 mm wrench or socket. Perform for both sides.
Attempt to install bar over the
studs, sometimes it will slide over with no problems. Because
the front towers are inclined in 2 planes of angularity-to achieve
caster-camber settings- the studs are at different angles in respect
to each other. To make the bar fitting easier- jack up the
front chassis so one side of the studs will be flush with shock
tower- loosely attach opposite side bar and nuts, then carefully
lower car so other side studs will raise up through bar holes into
Finish by removing jack and
tightening all stud nuts. I recommend using anti-seize on stud
