BMI Racing Double Wishbone Front End - Manual (Page 2)

Step 6
Install 2 black ball
studs into lower
arms and secure
with supplied
aluminum lock
nuts. Then attach
arm assemblies to
chassis and snap
the damper tube
onto the ball studs
Locate the left and right steering spindles. Trim the
steering arms length to the line molded on the part as
shown.
Step 7
Step 8
Locate the titanium front axles, four 4-40 alloy lock
nuts, and two alloy pivot balls.
Thread the titanium axles into the steering
spindles. Note that the threads on the axles that
go into the spindles are left hand. After the axles
are fully seated tighten an alloy 4-40 lock nut onto
the threaded stub coming out the back of the
spindle.
Thread the alloy pivot balls into the holes on the
steering arms and secure them with alloy 4-40 lock
nuts. Remember these are alloy pivot balls so
make the nuts snug. They are strong enough to
last a few racing seasons; but if you crank them
down, you can snap them.
Step 9
Locate 2 steel 1/8” king pins,10 1/8” shims, 4 e-
clips and 2 .020” springs.
Assemble upper arms as shown. Make sure that
the turnbuckle threads into the arm and eyelet very
straight. If it is not straight, this will mess up your
caster settings so be very careful. In testing on
carpet, we liked running 2 shims to the rear of the
block which will give you 6 degrees of caster.
