Purpose:<=
/b> This modificati=
on
will serve several purposes for your car. If you have a car that
been lowered (i.e. lowering springs), this modification is a must. Wh=
en
your car is lowered, the body of the car moves closer to the chassis changi=
ng
the factory geometry of your suspension. Your rear lower control arms
(LCA) will be offset from an angle parallel to the ground. This resul=
ts
in less force being placed on your LCAs causing=
your
tires to spin easier. The relocation brackets allow the LCAs be moved back to an approximately a level positi=
on.
On a stock ri=
de
height car, relocation brackets erve a
purpose at the drag strip. When used in conjunction with aftermarket
lower control arms and a set of slicks or "cheaters", a 0.2 second
reduction in the 1/4 mile has been proven.
Preface: <=

nstall
be sure you know how to use all of your shop
equipment. Take your time and be careful.
Notice: This installation has one
problem, I took horrible pictures. I had a backlight
condition and did not use the flash which resulted in very dark pictures of
objects close to the camera. I will be redoing this install in the ne=
ar
future to retake better pictures and to add more pictures that had to be
removed because they were so bad (dark). Sorry for any inconvenience.=
1. =
We placed the rear of the ca=
r on
two jack stands and chocked the front two wheels. We placed a set of rhino
ramps under the rear tires and let the floor jack down but left it under the
rear differential for added safety.

ate
telling anyone to cut their bracket. It is really a minor adjustment =
and
this is a muscle car. A small cut is not going to end my world, and it
had to be done. Besides, it makes the job SOOOOO much easier. :=
-) Cutting the bracket=
was a
very easy job for us. We used a battery powered =
DeWalt
reciprocating saw. I highly recommend a power tool for this job. =
; It
will greatly cut down on the install time. Just be careful not to get
drunk on the power and cut into the frame as I did. DOH! Figure 4<=
/b> 7. Place the shock mou=
nt on
the bracket is in front of the lower shock bolt mount on the frame. <=
span
class=3DGramE>Slide the the lower shock bolt th=
rough
the bracket and frame mount. Insert the original=
LCA
bolt. This might be a little difficult but it can be done. I us=
ed a
small pry bar and a screwdriver to move the bracket as needed (see Figur=
e 6).
It might take a few minutes, but the bolt will go in. Once the bolt is
through, hand-tighten the nut on the LCA bolt and lower shock
bolt! You will tighten both nuts to specification later. Figure 5<=
/b> Figure 6<=
/b> 8. Figure 7<=
/b> 9. 10. With the LCA bracke=
ts in
place with bolts back in, LCA nuts finger tightened, and the shock bolts
tightened, raise the rear differential housing up off the floor jacks about
1/4” and place the rear suspension in a “loaded” position=
.
The nuts should be tightened while the car is in a loaded position!&=
nbsp; Tighten the origina=
l LCA
bolts to 80 ft-lb. Tighten the lower bolt on the relocation bracket t=
hat

wer
the car. That is all there is to it. Comments:=
There is a defin=
ite
difference in traction on the 1-2 shift on street
tires. We completed this install a day after our local drag strip clo=
sed
for the season. :-( That means I don't have any track data to b=
ack
up my claim, but there is a difference. When used in conjunction with
slicks on a non-lowered car, a 0.2 second difference has been seen in the 1=
/4
mile. I have interviewed several LS1 owners and all have gained at le=
ast
0.1 seconds in the 1/4 mile. I installed the brackets on my 1999 Z.&n=
bsp;
My Z is not lowered; I wanted the better traction. Looking back on the
install, I would guess that this install would be easier if we had
unbolted both lower control arms at the same time instead of one side at a
time. This is just an observation, and I have not explored that optio=
n yet.
I will go back and redo this install at a later date and update my horrible
pictures (I will use the flash for sure) and unbolt both LCAs
and try again to see which is easier. The second side goe=
s a
lot quicker than the first side. The learning curve is basically stra=
ight
up after doing the first side. The horrible pictur=
es
were a result of me not paying any attention to my camera. The camera=
was
not using the flash because of the back light condition caused by the
surrounding light around the car. Pictures will be updated in the fut=
ure,
so stay tuned.![](3D"BMRBolt-OnRelocationBrackets_files/image002.jpg")
