GeneralInformation
Foreword
f you are reading
this, you are
embarking on a
mission to build
your own car, or at
least considering doing
so. I wanted to share
with you some of my
experiences and lessons
learned while working
with literally thousands
of people who have
completed this
undertaking with
us. The lessons learned
here are important and
will hopefully help
with your decisions as
well as with the project
and the completed car.
First of all, the idea of
building your own car
is NOT for
everyone. It is a
serious endeavor that
should be undertaken with care and consideration. The desire to build your
own custom car goes way back. It is part of our uniquely American car-
centric culture, and those who build their own cars are at the very center of
this. Since the earliest days of Hot Rodding, literally tens of thousands of
people have built their own cars. Even more have done restorations and
major customizations to existing cars. As fun as this project is, a person
should be candid about their abilities turning a wrench. This is not a place
for novices. That is even truer in racing, where danger and risk are part of the
Chapter

very definition of always trying to go faster. The late Carroll Smith wrote
something I really loved that speaks to this point.
“There is no magic! The one basic truth of successful racecar preparation
bears repeating. There is no magic. There is only logic, common sense,
forethought, vast amounts of hard work, and a fanatic dedication to the task at
hand”.
Carroll Smith
“Prepare to Win”
I can’t think of anything more appropriate to say about the right way to
approach the serious work of building your own car. Carroll passed away not
too long ago, but his accomplishments behind the Ford Lemans victories and
his contributions to the motorsports community continues in his writings that
are all at the top of my list of recommended readings for the car builder or
racer.
After being honest about the skills, responsibility, and dedication required to
build a car, I feel the need to talk about the PROCESS of building a car in an
equally candid manner.
The process of building a car is a lot like the process of having kids. As a
matter of fact, it’s absolutely the best analogy I can find (apologies in
advance to all of you without kids, try and bear with me). Both things are
easy to get started. With a car project you order a manual, talk to car guys,
get all excited over glossy photos and perhaps order a kit from us. With the
whole pregnancy thing, well for most folks that’s even easier to get started…
When my wife was pregnant with our first daughter I was sure we would
never have any more children. From the swollen ankles to the morning
sickness, to the delivery room scene from the movie “Alien”, the whole
process was difficult, and while she didn’t complain too much thru the nine
months, it was obviously hard work. Another thing, she wouldn’t have been
the best salesman for others considering getting started on the baby thing.
When it comes to the car project, once the kit arrives and the process begins
it is much the same as pregnancy. Frankly the degree to which a person
breezes thru the project or languishes is commonly a factor of skill, but still,
building a car for anyone is a tough job and there are inevitably issues. How
many times have you gotten the wrong part at NAPA, gotten home to realize
the alternator has a six ribbed pulley not five…? You will meet challenges
building this car and you will be frustrated at times. Thankfully there are
internet discussion forums where you can vent your frustrations and complain
about the idiots who designed this kit. We smile when reading these posts
because we know that while the pregnant woman complains, the mother
loves her children in an unreasonable and perhaps even undeserved way!

All the way thru the process, as you build your car, the seasoned guys at
Factory Five in tech support will help you. The larger community of Factory
Five customers will also be there for you, as the one thing that really sets us
above the crowd of other companies is the size, competence and enthusiasm
of our customer community.
When the baby arrives and when your car is done, there will still be more
work. With babies, it’s up all night, diapers, and strange maternity
contraptions that men don’t speak of in the light of day… With the car it will
be other challenges. Registration and licensing can be frustrating and laws
vary from state to state. A wrench dropped from 25 feet away will
inexplicably shoot sideways into any freshly painted surface and my favorite
was my own engineers who felt the need to test out how long an 8.8” rear diff
can run on a track without gear oil (answer, about three laps before deciding
to stop moving).
There will be highs and there will be lows, but in the end, there are few
parents who don’t treasure their children more than life itself, and there are
few Factory Five owners whose lives remain unchanged by the experience
and the artwork they have crafted.
It’s one of the greatest experiences in the world to raise children. It’s also
one of the most rewarding things I know to build your own car. Even today
at car shows, open houses, and events wherever Factory Five cars are found, I
smile to hear the inevitable first words every guy says to me… “Let me show
you what I’ve done”.
The cars that we build are more than cars. They are a reflection of us. The
badge of honor that comes with having built your own car is a special one
indeed. You will join a community of others who have earned their own…
and THAT is the story of Factory Five Racing and that is what awaits you in
this process.

President

Safety Notice
While there are many things to love and be proud of in our country today there are a few things that we
wish were different. With regret and a small amount of resentment we include the following warning
and statement of non-liability at the advice of men with soft hands and necks the size of pencils.
Motorsports involves the operation of machines and materials near the limits of performance. Racing
involves an inherent amount of risk. Any decision to proceed in the project of building one’s own
racecar must be made with the acceptance of personal responsibility. If, while building, driving or
racing this Factory Five Racing kit, should you become injured or die, it will be the result of your own
conscious decision and we at Factory Five Racing, Inc., disclaim any responsibility of any kind.
The procedures and recommendations contained in this book are to be used as a guide with the
ultimate determination of safe construction and race-worthiness to be made by you. If you feel uneasy
about whether you have the skills to build your own vehicle, DO NOT PROCEED. This project
involves building a car from the bare frame all the way up to a finished vehicle. It is intended for
individuals who have the skills and abilities commensurate with the scope of a project of this
magnitude.
This kit is only a collection of parts designed for use primarily as a race car. Factory Five Racing does
not build completed or partially completed vehicles. You are responsible for ensuring that the vehicle
you build complies with all Federal, State and local laws regarding its use. Except as may be specified
in writing, Factory Five makes no warranties, expressed or implied, on the products (parts, or kits)
offered for sale. All implied warranties of merchantability and fitness for a particular purpose are
expressly disclaimed by Factory Five.
While Factory Five products are thoroughly tested under actual race conditions, Factory Five cannot
control the quality of the installation or application of these products. The products offered for sale are
true race car components, the installment of which often requires considerable time and fabrication
skill. Before attempting any installation or assembly, the purchaser should determine the suitability of
the product for the intended use, the time, and level of skill necessary for correct installation or
assembly.
Factory Five does not make any warranty, expressed or implied. Purchaser expressly ASSUMES THE
RISK of all personal, property and economic injury, damage or loss, either direct or indirect, arising
from the use, misuse, or failure to determine the appropriate use of any Factory Five product.
Ford and Chevrolet, GM and Cobra are registered trademarks.
Factory Five Racing, Inc. is not connected to the holders of these marks.

Safety Tips
Read the manual. It is at least a good guide and place to start.
Don’t take short cuts.
Before starting work, make sure you have the proper tools, the required parts, and sufficient space
for the job. If you damage any parts, it will probably be because they were either not stored
properly or, the wrong tool was used to install them.
Don’t work when you’re too tired or upset. The car you will be building is capable of supercar
levels of performance, and your life depends on the quality of your workmanship.
Never work under a raised car unless it is well supported by stands intended for that purpose. Never
work under a car supported by a jack.
Always observe good safety practices such as the use of eye protection, protective clothing, and
gloves.
Keep the battery disconnected whenever you work on fuel or electrical systems and always keep a
fire extinguisher handy.
Don’t allow children in the work area.
Partially assembled cars attract a crowd. Keep garage doors closed or mark off work areas.
Make sure that all electrical equipment is grounded. If working alone, have someone check on you
periodically.
When using an engine hoist, make sure that the working load rating is correct for the weight.
Work in a well-ventilated and well-lighted area.
Use portable safety lights for under-carriage work. Never use an exposed bulb type light.
Be mindful of the environment. Avoid spills of solvents or engine fluids. If a spill occurs, clean up
immediately and dispose of it in hazardous waste containers
Never let a friend or someone else drive your car.
Always wear your harnesses.
Clean your build area after each assembly is completed. This will speed your build process as it
ensures that you know where your tools are and prevents tripping injuries.
It is impossible to anticipate all of the possible hazards. Care and Common Sense will prevent most
accidents

How to use This Book
This Assembly manual is intended to help you build your Factory Five Kit. This book will not explain
such things as engine or transmission building. A secondary purpose of this book is to use it as
reference for owners that want to do maintenance work on their cars or for those that purchase finished
cars, to understand their cars better.
This manual was written with the average weekend mechanic in mind. It is best to follow the manual
step by step but if there is a part missing from the kit move to the next section and come back to it late
when the part is available. If the instructions are followed then the resulting car should be a great
handling sports car.
We have included an Icon key as the beginning of each section that contains
useful information for each assembly that details the tools needed for that
assembly, what assembly in the kit parts are packaged in that are needed for that
step and any useful information or warnings.

This chapter deals with the donor parts needed in addition to the parts that we included with our kit.
Many people choose to use parts from a single Corvette donor. If you are not going to use a donor car
but choose to acquire parts separately, this section may still be useful. The complete list of parts
required to build the FFR GTM is included in the Appendix of this manual. For specifications on the
Corvette donor by year, see the Appendix.
The fifth generation Corvette (the C5) was introduced by GM in 1997 and produced until 2004. Any
C5 Corvette (standard or Z06) can be used as the donor for the FFR GTM.
The transmission you will use for the GTM is the Porsche 911 G50 series gearbox. These
transmissions can be found in 5 or 6 speeds and with various gear ratios. For example, the Porsche
993 used a 6 speed G50. Factory Five supplies an adapter kit for 1990-1998 G50-03/05, G50-20 and
G50-52 Transaxles. For other styles, years and brands see the Appendix

Where to look
Junkyards – If they do not have one on the lot, usually they go to auctions weekly and can get what
you want.
Newspaper classifieds.
The Internet.
Search “Factory GTM” on Ebay. There are companies that sell “GTM Corvette parts Kits” without
engines for $5,000.
Below is a list that contains salvage dealer websites we have found to be useful. Many of the dealers

Price – Donor Car
Whether you’re buying a complete salvage yard car or a bunch of parts, it’s important to remember
which parts are worth money to the salvage yard and which ones are of little or no value. The drive
train, body panels and interior are of the most value. The other pieces such as the steering shaft, pedal
box, and other miscellaneous pieces usually are very inexpensive for the yard to include. When
negotiating the price from the parts yard, you might get a better deal if you let them have the parts you
won’t be using. We believe it is usually better to take the parts off yourself, because you will inevitably
do a better, more careful job. If you are using parts that are already taken off, you gain the advantage
