Installation instructions
4 point and 2 point rear standard and arched strut tower brace

Read all instructions before beginning work. Following the
instructions in the proper sequence will ensure the best and the
easiest installation.

Suggested Supplies:
17,18,19mm Sockets. Torque wrench. Reciprocating saw w/ blade. File –
Half round. Shop scissors. Masking tape. Gaffer’s tape (black). Shop

1. First open both doors and the trunk and then flip the rear seats
down. Pull up the velcro attached fabric flaps on the rear seat backs
and fold towards the front of the car. Remove the cargo net ( if
equipped ), and remove the trunk floor by slipping it up and out of
the widest portion of the trunk opening.

2. Now remove both trunk side panels by removing one wing nut behind
the taillight. Gently pull near the lower cargo tie down to pop a
christmas tree fastener out, grab the panel on both sides of the top
near the upper cargo net tie to gently work a second christmas tree
fastener out.

3. Lean into the car from the cabin and get both hands under the
forward bottom edge of the panel to ge the single large christmas tree
fastener out. This one means business so hang on tight and gently rock
back and forth – it will come out. Reach into the trunk pull the side
panel out around the rear trunk panel and free from the car. Repeat on
the other side.

4. ** For the 4 Point rear bar only.
Use a 16mm socket to remove the single nut on the right side of the
rear seat brace. Insert the REM brace from the trunk gently set over
the exposed shower towers. Place the 2 large powder coated washers on
the other and unused factory stud near the left side of the rear seat

5. From the trunk, tilt the front edge of the brace up and visually
insure the brace now drops down completely around the outside of the
rear most shock bolt bosses. **** 4 Point bars only check both sides
and tilt the brace down to touch the rear seat base studs. Lean into
the rear of the cr and press the brace down over the seat base studs.
It may take a little effort due to slight powder coat interference;
use a rubber mallet for a little extra force if you like.

6. 4 Point rear bar only: Hand thread on the factory nut to the right
side seat base stud, and install the provided large lock washer and
nut to the left side seat base stud over the REM brace.

Return to the trunk and place the 4 powder coated cups upside down
over the 4 rear shock bolt end and bosses to trap the rear brace in
place. Install the provided lock washers and nuts.

7. 4 Point rear bar only: Torque the seat base studs on both sides to
42ft. lbs. and then torque the smaller stud nuts to 32ft. lbs. Do not
over tighten the tower cap nuts or you will crush the caps. Note: The
torque spec for the rear shock bolts which are installed from the
bottom of the car is 38ft. lbs, if these are not correctly torqued to
begin with it is possible tightening the REM bar cap nuts could back
the shock bolt out slightly. Retorque the bolts prior or the tower cap
nuts if there is any doubt these fasteners are tight to spec.

8. If you wish to reinstall your interior panels, measure from the
trunk near the exposed panel to the rear crossbar of the brace, and
from the trunk floor up. This measurement should be about 23 3/4″ back
and 7 1/2″ up on center.Do the same for the forward bar. Using masking
tape, tape up the matching area on the side panel and mark it up to
find the cutting point as in the attached photo. Using a razor knife
carefully cut the center out in about 1 inch diameter for now to
insure the holes are correct. **Note** We highly recommend the use of
our close out panels, part #306-COP for a clean finished look.

9. Using a pair of shop scissors or other sturdy cutters, cut a slit
down the panel at the same angle of the nearby panel fold to the
center of the first hole, and between the holes. Using the scissors,
razor knife, or your hands, cu and remove the insulation on the panel
back around the holes and for about 1/4″ on either side of the slits.

10. Test fit the panel into place by slipping it on either side of the
bar, working it into place. Note where the bar interferes and mark
upon your tape for areas to cut further. Remove the panel and re-trim
until you have about 1/4″ clearance around each bar. This will make
the panel easy to install and remove as needed and noto warp over time
due to being forced into place.

11. To finish use an 8inch section of the black gaffers tape placed
right up underneath the brace on the wheel well to hide any body color
showing through when you are done. Install the panel, christmas tree
fasteners, and the taillight wing nut. A little velcro ( rough side
only ) on the back of the slits help close it up nicely. Repeat for
the other side panel and insure the interior is well seated including
the small clip (1 per side) holding the carpet in place between seat
and trunk.

12. 4 Point bar only: Carefully install the trunk floor and slide it
forward until it hits the REM brace. Lay making tape down on the
floor, and then mark up the area of interference for cutting. Using
the attached picture as a guide cut one side first, and use the piece
you cut out flipped upside down to draw around and cut the other side,
this will help you achieve a symmetrical cut for both sides. Next cut
off a 1/4″ strip between the two holes. Using the half round file,
clean up all cuts and sharp edges, vacuum the floor thoroughly. Test
fit and trim again if needed.

13. Reinstall the trunk floor, cargo net, and attach the velcro net,
and attach the velcro flaps, put your seats up and insure all the
panels and fasteners are installed. Close up the car and start
enjoying your new brace.
