Race Procedures

Entry Fee amounts will be determined by the RETRO and the Race
Host. Entry Fee should include race day "pit pass" fees. Pit Pass
fees for non race days will be separate from Race Entry Fees. 

Tech Inspection will be held prior to qualifying and the races.
The tech schedule should be announced/posted and clear and prior to the
event/race. All cars must pass technical inspection prior to the cars being
entered into the race. Chassis, bodies, motors, tires may be marked to
insure no changes are made after tech and/or during the races.

Cars that do not pass tech will be allowed time to make changes to
pass tech. Cars that are not repaired in the allowed time may not be
allowed to qualify and added into the lowest race if repaired in
time. 

Cars that arrive late and after tech closing time may be added
into the lowest race of the class the car is being entered into. 

After cars pass tech inspection all cars are to be impounded and
to stay impounded at all times prior to qualifying and racing. The race
committee/control will control which cars are to be in impound and when cars
may be released from impound. Cars in impound are not to be touched by anyone

All Cars are subjected to be re teched at any time during an
event/race. If they do not pass tech they will either be allowed back in the
race after passing tech or disqualified. 

Tire cleaning will be allowed during the race(s). The only cleaner
allowed will be the official cleaning fluid provided by the RETRO . The
cleaning fluid is to be applied to the tires either directly by using a rag.
Any transfer of cleaning fluid to the track will result in disqualification. No
other fluids or substances are allowed on the tires during the racing. If another
fluid other than the official cleaning fluid is found to be used during racing
will result in disqualification. 

Other cleaners/tire treatments are allowed prior to tech and
during practice as long as they do not interfere or change the racing surface. 

Any other fluids IE: braid juice, oil, etc found to be used in
excessive amounts and affecting the racing surface will result in the drivers
disqualification.

TIRE CLEANING

Drivers are prohibited from gluing their tires and/or the track surface in practice
sessions or during any race. Racers are prohibited from cleaning the track
braid at any time. The track surface may not be altered by a racer at any time
during practice sessions, or in the race.

Glue boards of any kind are not permitted to be used at any time during RETRO
events.

Tires may be cleaned by drivers during the races and/or during lane changes.
The only approved fluid for cleaning tires during a race is lighter

Tire cleaner may not be transferred, or applied to the track surface. Doing so
will result in disqualification.

Tire treatments (Zip Grip, Sticky Fingers, Bardahl No-Smoke, ‘home-made brews’
etc) may only be applied to the rear tires before a car is presented to tech.
No tire treatments, or glue of any kind will be permitted to be used during a
race. Rear tires on all cars must be ‘dry’ when presented at tech. Applying
tire treatment and/or any type of glue to tires during a race will result in
disqualification.

Racers may not leave any residue (braid juice, oil, lighter fluid etc.) on the
track surface while servicing their car during a race event.

No braid juice application, oiling, and tire cleaning will be permitted once
the car is presented for tech and is placed in secure impound. Applying braid
juice and oiling the car is not permitted prior to qualification/time trials. A
racer may oil his car and apply braid juice once his one-minute qualifying
session has begun. 

Track condition and surface is to be prepped on the day prior to
the race/event. The surface should be cleaned and sprayed and ready for the
first day of practice for the event. Racers are not allowed to alter the
surface in any way and doing do will result in disqualification. No racer applied
glue or cleaning will be allowed during the event.

LOSS OF CAR COMPONENTS

If a car loses its front wheel(s) and/or front tire(s), or the driver figure, a
racer will be permitted to finish the heat, but will be required to make the
needed repairs before being permitted to start the next heat and continue in
the race. 

 
Car Repairs: Car repairs that take place during green flag conditions. Cars that have been repaired during green flag conditions and returning to the track under green flag/power on conditions may be placed back on the track in front of the driver on the main straightaway. Cars that have been removed during green flag/power on conditions to be repaired and returning during a lane change, must go back to the position on the track the car was removed during green flag/power on conditions.

RACE FORMAT

There are only two Race Formats that RETRO events are to use along
with Qualifying Options

Qualifying there are two options. One is 45 seconds to one
minute with power on and racers fastest lap is recorded along with 2nd fastest
lap in case of ties.

 The second option is Laps and Sections. Racers run a 45
second to one minute period and the total laps and sections ran determines
qualifying positions. Sections will have to be marked carefully when using this
option.

 There will also be "lane choice/pick" based on
qualifying position by the driver for all races.

PRE-RACE WARM-UP PERIOD

A one-minute warm-up period will be conducted prior to the start of each Main.
The eight drivers starting the race will be given the opportunity to practice
first.
All sit-out drivers will then be given the opportunity to warm-up following the
eight racers starting the race. Drivers may oil their cars and apply braid
juice prior to the start of the race. Sit-out cars must be taken to the impound
area following the warm-up session.

 Format One and Done

Qualify all cars using one of the above options. Cars are seeded
into Main Races by qualifying times. Example: 32 cars. Qualifiers 1-8 into A
Main, 9-16 into B Main, 17-24 into C Main, 25-32 into D Main. The running
order is D main, C main, B main, A main.

Marshaling order is A main drivers marshal the D main, the D main
the C main, the C main the B main and the B main the A main.

 All cars finishing sections are to be marked at the
conclusion of each race and when all Mains have been completed the Overall Lap
Totals and Sections determine the Official Finish of the race/class.

 
Format Two Move Up 

 Qualify all cars using one of the above options. Cars are
seeded into Qualifying Races by qualifying times. Example 64 cars.

Qualifiers 1-8 go into the Semi Races  9-16 into A qualifier,
17-24 into B Qualifier , 25-32 into C Qualifier, 33-40 into the D
Qualifier, 41-48 into the E Qualifier, 49-56 into the F Qualifier and 57-64
into the G Qualifier.

 The running order is G, F, E, D, C, B, A 

 Marshaling order is A drivers marshal the G, the G the F the
F, the E the D, the D the C, the C the B, the B the A

 All cars finishing sections are to be marked at the conclusion
of each race and when all Qualifying Mains have been completed the
racers with Top 8 Lap totals move up into the two Semi races along with
the Top 8 Lap time qualifiers.

 Two Semis are to be run. A Semi and the B Semi. The Top 4
finishers from each Semi move up into the A Main.

 The A Main is run to determine the Winner/Champion of the
race/class/event.

 Round Robin races may be run depending on number of entries
in a race/class/event and as a time saving measure. All races should be seeded
to include the same number of drivers in each race or on the track at the same
time.

SIT-OUT PROCEDURES

In round-robin races where sit-outs are used, the following procedures will be
followed: All sit-outs will take place after a racer completes his heat on the
WHITE lane. A racer going to a sit-out must take his car IMMEDIATELY to the
sit-out impound area in the condition in which it finished the heat. A racer
may NOT work on, repair or service his car in any way while enroute to the
sit-out impound area. Doing so will result in a 10-lap penalty. The entire car
and/or components must be submitted to the sit-out impound area. No exceptions!
In the case where a car is being worked on in the pits during a white lane
heat, the entire car and/or components must be taken to the sit-out impound
area IMMEDIATELY when the heat ends. Failure to do so will result in a 10-lap
penalty. A sit-out car may not be touched while it is in the sit-out impound
area by ANYONE, including the race director. In the event there are multiple
(more than one) sit-out heats, a racer may not work on, repair or service his
car during the ‘off’ periods between sit-out heats. A car will be released to
the driver after serving his sit-out heats.

Race Duration 

Can Am, WSC Coupe and F1-Indy 
Classes are to run 3 minutes on heats with 2 minutes
off between heats for lane change and pitting of cars.

Stock Car and Flexi 
Classes are to run 2 minutes on and 2 minutes off.

Retro AngleWinder G7-68
Class duration determined by race promoter for either 2 or 3 min

in the class being raced. All racers will have to turn marshal and there will
be no exceptions except for physical reasons. Substitute marshals will be
permitted as long as it is approved by the officials in charge and the racers
in the race. Marshals who miss or refuse their duties will be subjected to
penalties or disqualification. Racers are expected to stand when performing
marshaling duties, except in cases when marshals must kneel to avoid blocking
the view of the driver’s panel. Standing marshals must also exercise care to
not block the view of drivers, and may be asked to reposition by the drivers
and/or race director.

Specific track calls will be discussed prior to each race meet.


Lane Change Cards

Lane Change Cards are to be used during the lane changes during
the races. Any racer found to not be using a lane change card will be penalized
5 laps for each infraction. Racers found to be moving the position of the car
