The factory at least gave us a strut tower
brace for the new GTO but, unfortunately, it is little more
than a cosmetic piece. The factory brace is made from thin
wall 1" x .083" seamed tubing and does little
to reinforce the strut towers. The BMR strut tower brace
is made from 1-5/8" x .095" seamless tubing and
uses heavy duty 3/16" mounting plates. Available in
Black Hammertone
or red powdercoat. Also available painted factory colors
for an additional $40. NOTE: Some manual
'05-'06 cars may require bending the clutch reservoir bracket
for proper clearance.

Remove almost 10 lbs. from the nose of
your car with a BMR aluminum skid guard. Laser cut and CNC
formed from .160" aluminum, our guard weighs 5.75 lbs.
compared to 15 lbs. for the stock steel guard. Easy 15 minute
installation. Shipped bare aluminum, powdercoating available
for an additonal charge.

SUBFRAME CONNECTORS
BMR subframe connectors provide the ultimate
in frame rigidity and add to the overall handling ability
of the car. They are manufactured from 1.5" x 2"
x .120" rectangular tubing and laser cut, 1/4"
mounting and weld plates. The subframe connectors tie into
5 structural areas and provide 4 seperate weld points. The
rear mount replaces the factory suspension cradle mount
allowing full accessibility to the cradle after the subframe
connectors have been installed. Available in Black
Hammertone or red powdercoat.

DRIVESHAFT SAFETY
LOOP
Most tracks require driveshaft safety loops
for ET's quicker than 12.99 in the quarter. Our NHRA legal
safety loop welds onto the factory floorpan reinforcement
and has locating holes for proper positioning. Two piece
design allows installation without removing driveshaft and
will fit driveshaft diameters up to 3.5". Available
in Black Hammertone
or red powdercoat. NOTE: Will not clear '05 resonator.

HARROP DIFFERENTIAL COVER WITH
POLYURETHANE MOUNT
These custom differential covers stabilize
the differential mount, reinforce the case, and provide better
cooling with increased oil capacity. The factory rear mount
is a very poor design. The entire rear cradle and suspension
is mounted by two front bushings and one rear. The rear center
mount attaches to the cover and is responsible for controlling
movement and maintaining pinion angle. This improved rear
mount spreads the load out over a greater area by using two
bushings, each to the side of the cover. Less differential
flex results in minimized wheelhop and quicker response to
braking and acceleration. Simple bolt-on installation. NOTE:
Although this cover clears OE exhaust, aftermarket exhaust
systems may require modification.

DRAG BAGS
Does wheelhop plague your new
GTO? This is a common side effect in independent rear suspensions
caused by the inability to properly dampen vertical wheel
movement with applied torque. Combine this with the minimal
rear suspension travel of the new Goat and your bouncing off
the bumpstops every time you stab the throttle. An easy solution
to this is stiff rear spring rates, however ride quality then
becomes an issue as well as excessive oversteer. The best
solution is a set of BMR Drag Bags. This is an old solution
to a relatively new problem. Spring rate can be altered by
simply adding air (without effecting ride height) and ride
quality remains un-effected when the bag is deflated. Fairly
simple 2-3 hour installation time. NOTE: Works with OE springs
only.

KONI ADJUSTABLE REAR SHOCKS
Koni makes one of the best sets
of adjustable rear shocks for the late model GTO's. Valving
adjustment can be done through the trunk by simply turning
the supplied knob. Great handling mod and very useful in controlling
wheelhop.

HEAVY DUTY DRIVESHAFTS
The factory driveshaft in the GTO is the
weakest part of the entire driveline. It's a two piece design
that is only 2 inches in diameter and uses rubber mounts
instead of u-joints. Not only do the rubber mounts contribute
to wheelhop, they are notorious for failing on even slightly
modified 6 speed cars.
Our heavy duty driveshafts are a one-piece
design that use forged 1350 series u-joints. Each driveshaft
comes with a cryogenically frozen front yoke and a custom
machined 300M billet pinion yoke adaptor (shown below).
NOTE: Due to the physical size of this driveshaft,
the factory exhaust may require some modification. Most
aftermarket exhausts tested do not have clearance issues.
Steel driveshafts not recommended for 6 speed cars. Driveshaft
needs additional spacer if using Harrop Differential cover.

HEAVY DUTY CV
SHAFTS
OE CV axles typically won't
fail because the driveshaft goes first. Once the driveshaft
is upgraded, the CV's become the next weak link and typically
break at the axles' transition on the shaft. A broken CV axle
can cause thousands of dollars in damage before getting the
car stopped. Don't risk it, our heavy duty CV axles use custom
billet CV joints and 300M axle material. The axle itself is
1-3/8" diameter compared to the OE 1-1/16" and is
capable of handling 800+ RWHP.

NOLTEC BUSHINGS
The durability of polyurethane
is superior to the rubber components used in your new GTO.
Road salt, oil, and many other common under car contaminants
will eventually destroy the rubber bushings on your vehicles,
not to mention the weight and torque forces that typically
compress most rubber permanently.
Polyurethane components stand up well to contaminants that
often destroy rubber and have been engineered to give longer-lasting
performance and not compress permanently. Additionally, Noltec
addresses other common GTO issues such as providing camber
and caster adjustment that was otherwise unavailable.
The lever kit allows for remote actuation
of the Big Switch. The kit includes an 18" long, diameter
aluminum threaded rod, T-handle, mounting bracket and necessary
hardware. A "push off" decal is included. Accepted
for IHRA/NHRA competition use. Click HERE
for Big Switch features.
