"...saving hours of fabrication
time and effort, while significantly
shortening the timeframe to deliver
a top-tier performance vehicle."
The ultimate bumper-to-bumper chassis solution for high-horsepower, bigtire, pro-touring projects is now available as an off-the-shelf item. Builders
can take advantage of Chassisworks robust engineering and manufacturing
capabilities, saving hours of fabrication time and effort, while significantly
shortening the timeframe to deliver a top-tier performance vehicle.
The complete system consists of the following: Chassisworks’ fabricated
front subframe with modified engine position and drivetrain angle;
replacement double-walled rockers; 3 x 2” subframe connectors; choice of
4 x 2” canted-4-link or torque arm with watts link rear frame; fabricated
transmission-tunnel and lowered seat-mount assembly; complete interior
tin kit, including front and rear floor, wheel tubs, trunk floor, and rear
firewall. The exact-fit roll bar or roll cage with forward support struts can be
added to create an extremely rigid performance platform suitable for 1,000
horsepower engine combinations, with room for large enough tires to put
that much power to good use.
Tire Sizes (‘67-69 Camaro): The front subframe accommodates tires up
to a 12.25” section width with 26.3” overall height (305/30-19) with a
full 30-degree turning angle. The rear has ample room for 14.25” sectionwidth tires with 28.2” overall height. The prefabricated wheel tubs allow
room for even larger tires when they become available.
• Fully-optioned system engineered
to support over 1,000 hp in
performance handling applications
• Double-A-arm front suspension
with rack-and-pinion steering
• Highly adjustable geometry canted-4-link or torque arm with
watts link rear suspension

Front Subframe System
Similar in construction to Chassisworks existing double-Aarm Camaro subframe, the enhanced gStreet subframe
features redesigned frame rails to increase
maximum tire section width from 285 to larger
305-wide (12.25”) tires. Engine mounts are
repositioned rearward to improve weight distribution
and leveled to provide bellhousing, transmission and
exhaust clearance necessary for the significantly lower ride
height of the complete frame system.
One-Piece 4 x 2” g-Machine Crossmember
Bent-tube, billet-component crossmembers are a
completely closed, rigid structure with greater strength
and resistance to bending and twisting than other
designs. Formed from a single piece of 4 x 2 x .120”
steel tubing, large-radius mandrel bends are placed
at each end to distribute loads throughout the
crossmember, eliminating fatigue points at critical
areas. Slots for the billet-mount tabs are machined in
a large horizontal machining center with dedicated
fixturing to guarantee correct component geometry,
ensuring the suspension moves as designed.
Locating features are machined into each crossmember to
enable self-positioning of billet components.
Interlocking-Slot-Tab Technology
Self-fixturing female slots used with machined male
tabs provide an interlocking assembly method that
enables A-arm, rack and pinion, and shock mounts to
be accurately positioned in all axes. This guarantees
the suspension will perform as designed. Noninterlocking designs are not nearly as accurate after
welding. Superior spray-arc welding process produces
the best weld penetration with excellent appearance.

Replacement Double-Wall Rockers
A significant amount of chassis strength and rigidity is gained by installing the optional prefabricated doublewall rocker sections. The inside shell of the OEM rocker is removed, revealing the empty outer-body wall,
and replaced with the heavier-walled Chassisworks’ rocker with boxed interior structure. Seat belt mounts
and wiring access channels are built into the rockers to simplify final vehicle assembly. The improved rocker
provides a far superior structure on which to mount the rear-frame crossmember and roll bar or roll cage.
Main hoop and cage side reinforcement plates, such as those used on OEM sheet metal, are not required
with the Chassisworks’ rockers.
Firewall Rocker End (left):
The new rocker extends through
the firewall and features a large
support gusset.
Stainless Caps (left/right):
Access holes at each end of the
rocker allow wiring or plumbing
to be safely routed through each
rocker structure. Removable
stainless steel caps are provided
for easier installation of
bulkheads or grommets.
Back-Half Rear Frame
Chassisworks’ canted 4-bar Camaro rear frame system is a truly
versatile high-performance suspension solution, suitable for highpower, big-tire, pro-touring projects that require more strength and
stiffness than systems mounted to the OEM sheet metal can provide.
Achieving a very low rocker ground-clearance height of 4” with
massive rear tires was one of the system goals. We are proud to
state that nearly all of the normally ‘one off’ chassis and sheet metal
fabrication that is required to tuck extremely large tires, drivetrain,
and exhaust into your Camaro is expertly built into a neatly packaged
‘off the shelf’ system. To ensure perfect geometry and fit with
minimal effort while saving considerable installation time, rear frames
including front crossmember ship as a factory-welded subassembly
with unattached 2 x 2” trunk outriggers and 3 x 2” front subframe
connectors for easier installation. The 4 x 2 x .120”-wall rear frame is
designed with minimal rise over the rearend housing and maximum
clearance above the driveshaft and third-member to allow more room
in the rear seat and trunk areas without sacrificing suspension travel.

Frame Manufacturing
All components are professionally spray-arc-welded
by Chassisworks’ welding staff in a controlled
environment using computer-designed fixtures and
production-quality equipment.
Tall driveshaft loop allows body to sit lower over the
drivetrain without risk of driveshaft contact. Crossmember
features factory-welded, dual 4”‑ID exhaust ports.
Multiple mounting points for each of the
suspension components, including shocks, control
arms, and anti-roll bar, enable highly adjustable
suspension geometry that can be fine-tuned to
match the performance requirements and weight
distribution of your specific vehicle. Suspension
component options include tubular-steel or billetaluminum suspension links with pivot-ball ends,
factory-welded FAB9™ housing, ball-end anti-roll
bar, and VariShock coil-over or air-spring shocks.

Factory-Welded Seat Mount Assembly
The seat mount area can be an extremely timeconsuming area of the chassis to manually
fabricate. Seating position, overall rigidity of
the area, strength of the mounting bosses,
and adequate drivetrain clearance are all
extremely important for safety and comfort.
Chassisworks addresses these issues with a
prefabricated, factory-welded assembly (shown
below) that simply drops into place for final
welded installation.
To improve driver comfort, the seating position
is lowered 1” to provide additional headroom
and increase visibility below the windshield
brace. The front crossmember is specially
fabricated to cleanly transition from the
tunnel’s sharper bends over the transmission
to the larger U-bent panel between the front
seats. The rear of the hump features a layered
inset to perfectly position the adjacent hump
panel. Rear tubular supports are notched to
achieve the lower seating position and straddle
the subframe connector. All seat and safety
harness mounting locations are integrated into
the factory-welded assembly.
Installed lowered-seat-mount assembly shown with prefabricated
front floor, transmission tunnel, driveshaft tunnel, and rear floor.
Prefabricated Floor and Wheel Tub Kit
The Camaro prefabricated floor kit replaces ALL floor and drivetrain-tunnel sheet metal from the base of
the firewall to the rear tail lamp panel. Large sheet metal spans are bead-rolled to strengthen each panel,
significantly reducing flex and vibration. To facilitate clean, rapid, and accurate installation, folded lips, inset
lap joints, and plug-weld holes are designed into each component.
To accommodate the significantly lowered ride
height of the frame system, the transmission
and tunnel have been moved upward. The
drivetrain tunnel provides adequate clearance
for the larger T-56 transmission and dual
3”-diameter exhaust.
The rear floor panels feature contoured flares
for exhaust clearance; note the intricate fit of
the tunnel, floor, and rear seat pan. The height
of the driveshaft tunnel section and wheel tubs
also hint at the position of the rearend housing
in relation to the vehicle floor. The seat pan
and rear firewall show the pre-drilled plugweld holes, a simple but timesaving feature.
The rear seat pan follows the top edge of
the frame rails and continues into the trunk.
This installation shows the optional remote
shock reservoir mount insert. The wheel
tubs, fuel tank, and side panels close out the
trunk floor. An optional billet battery mount
is also available.
The optional stainless steel fuel tank really
completes the look of the trunk. Sending unit
and trunkfill gas cap are shown. A remote-fill
hardware set is also available.
gStreet Exact-Fit Roll Cage
High-clearance cage sides, windshield brace, and
rear struts makes our Exact-Fit roll cage an excellent
choice for pro-touring performance applications to
add a level of protection and increase chassis rigidity. Cages are mandrel bent in a variety of steel tubing
types, including 1-5/8 x .134" mild-steel, 1-5/8 x
.083" 4130, 1-3/4 x .134” mild-steel, and SCCAcompliant 1-3/4 x .125” DOM. The removable back

Swing-Out Clevis Sets
Dual-purpose design makes a roll-cage side
bar or back brace fully removable — or,
simply swing it out for easy entry! In gStreet
applications, clevis sets are provided for the
driver's and passenger's cage-side bars, and for the
main-hoop back brace. Clevis tube adapters match the
specific ID and OD the selected cage or roll bar. Swingout side bars are NHRA-accepted.
Safety Notes – gStreet Roll Cage/BarFor
safety purposes, roll-cage padding must be applied
along any areas of the cage that occupants may come
into contact with. Due to the additional cage-side
and rear-strut bends, and removable door bars and
back brace the g-Machine cages are not intended for
competitive motorsports. Our competition series rollcages are designed for ultimate strength and safety, and
are better suited for serious competitive applications.
