Midwest Drift Union 2015 Rulebook
Please Read:
These are the Midwest Drift Union Competition Rules and
Regulations for the 2015
season. Although we try our best to avoid updates midseason,
they may occur. Please
verify you are using the most current version when reviewing
throughout the season.
NOTE: This rulebook is not as indepth as the Formula DRIFT
Professional Rulebook.
The Midwest Drift Union rulebook should not lead you astray,
however the Formula
DRIFT rulebook is updated more frequently than ours and we may
not catch every
update and/or change they make. If you eventually plan on
competing in Formula
DRIFT, please take the time to familiarize yourself with their
rulebook in addition to ours,
so you can plan your build out accordingly and save yourself
both valuable time and
money. If you have any questions, feel free to contact Nick
Swann at
nick@mdudrift.com

be ejected from the event.
No refunds will be given.
12. Failure to follow the rules or any instruction from
racetrack staff will result in
immediate ejection from the event and, depending on severity of

be banned from all future events hosted by the group at all
tracks. We’ll also make fun
of you and tell all of our friends that run other events.

about the doors and
windshield. The halo must be connected to the floor with two (2)
front down tubes. The
Halo bar must not contain more than four (4) bends totaling no
more than onehundred
eighty (180) degrees.
Front Hoop: A front hoop is one (1) continuous length of tubing.
Starting at the floor, as
far forward as possible, and then following the “A” pillar up to
the roof. Then, following
the roof, windshield line across the vehicle and down alongside
the other “A” pillar to
the floor. No more than four (4) bends totaling no greater than
one hundred eighty (180)
degrees will be permitted. The front hoop must be connected to
the main hoop by
means of two (2) horizontal bars, one (1) on each side above the
doors.
Rear Braces: The main hoop must have two (2) braces extending to
the rear. The
braces must attach as near to the top of the main hoop as
possible and no more than

form an “X”. Diagram
4.0 If a parallel design is used a minimum of two (2) vertical
bars must be installed,
joining the upper and lower bars.
Padding: All roll cage surfaces that may contact the driver
should be padded with
highdensity padding. It is not required though recommended that
all padding meet SFI
specification 45.1
Drivers that fail to follow this rule will not be eligible to
tandem.
Roll Cage FAQ:
1. Aftermarket roll bar, at a minimum, is required for all
convertibles for road course
events. For parking lot events, if no roll bar is present, roof
must be up and properly
fastened.
2. 6point roll cage with harness bar and door bars required for
Group A.
3. Roll cage must have X or NASCAR bars on both front doors.
4. Must have diagonal in main hoop extending from above driver's
head to passenger
floor and harness bar must extend the full length of the main
hoop and be positioned for
proper harness mounting.
5. Rear mounting bars must tie in at the rear shock tower.
6. Front cage design can be halo or apillar bars. Roof bar is
required if using apillar
bars.
7. Dash bar is recommended but not required.
8. Minimum tubing specification for all cars is 1.5”x0.095 DOM
SAE 1018.
9. Cage must comply with current SCCA/NASA specification.
10. For boltin cages, OE crash structure cannot be removed or
modified. Ebay or
“Tuner” boltin cages are not sufficient for tandem.
11. Roll bar padding is required wherever the driver or
passenger may come in contact
with the roll cage, i.e. halo, door bars, lower apillar bar.
Roll bar padding can be any
type of foam padding designed to be used for this purpose. No
pool noodles, home
depot pipe insulation, etc. SFI rated padding is recommended but
not required.
Harnesses and Seats:
1. Harnesses must be properly mounted and not expired. Harnesses
must be FIA or SFI
rated and within the date range specified on the belts.
2. Harnesses must be mounted using correct hardware. If using
eye bolts and bolting
through the floor, must use fender washers on both sides to
spread the load. Harness
shoulder straps must be mounted to a roll cage or separate
harness bar and should not
be outside of 20* of horizontal. The seat cannot be used as a
guide for the harness. No
harness mounting points can be attached to the seat or seat
rails, they must be
attached to the chassis.
3. If car does not have a roll cage, a harness bar can be used
to mount the shoulder
belts when using a 4, 5 or 6point harness. Must meet mounting
requirements listed in
item 2.
4. 4, 5 or 6point harness required for car with a roll cage
installed. 5point belt
recommended.
5. If harnesses are not properly installed and in compliance
with FIA or SFI
specifications, you will not be allowed to drive until this rule
can be met.
6. Please refer to manufacturer's specs for proper installation
and maintenance
procedures.
7. If stock seats or nonFIA approved reclinable bucket seats
are used, stock seat belt
must be used. Aftermarket harnesses are not allowed to be used
with these seats.
8. If race seats are intended to be used with stock seat belt,
the lap belt part of the seat
belt must pass through the holes in the side of the race seat.
