steps for you to complete when seeking registration of your vehicle.
Provided with your Factory Five Racing Coupe kit is a Manufacturer’s Certificate of Origin. This
document records the origin of the vehicle and is not a vehicle title. The component kit that we
manufacture has no VIN number. The number stamped on the frame matches the Certificate of Origin
and is the kit serial number.
In most States, upon completion of your kit, you need to bring this certificate along with receipts for any
parts used on your car and a copy of our invoice to your State DMV. Some states like Massachusetts
have a separate vehicle inspection division for specialty cars and custom built cars. Often times this
division handles “salvage” vehicles as well.
We know you will be excited about driving your car. Take the time to make sure you have made it race-
worthy and safe and legal before you get behind the wheel.
Wheels
For the
FRONT wheel, use the following equations:
1987-1998 Spindles: (width/2) +1.25”
1999-2004 Spindles: (width/2) +1.50”
Only 7”-9” wheels are recommended for the front. If using a wheel wider than 7”, FFR front lower
control arms are needed to prevent the wheels rubbing the control arms.
