  • Air Pressure For Tech inspection: Left sides 20 lbs/ Right sides 28 lbs.


Unapproved tire change is a two (2) lap penalty – For a tire to be changed during a race without penalty, the tire must first be inspected by an SRL Official and must be deemed as flat (10 lbs. or less Left Side / 18 lbs. or less Right Side), or has severe wheel damage.


Steps for an Approved Tire Change:

  1. The team should notify the SRL Officials of a tire issue prior to entering Pit Lane and must stop at the inspection station on Pit Lane, or proceed as directed.
  2. SRL OFFICIAL PRIOR APPROVAL: No crewmember is allowed to touch or inspect a tire before the SRL Official. If a tire is low on pressure, or has severe wheel damage, it must be first inspected by an SRL Official to be changed without PENALTY. Once inspected, if the tire is low on pressure and considered flat, or suffers from excessive wheel damage the tire may be changed by the team with no penalty. Again, stay clear of the tire until an SRL Official inspects it.
  3. PENALTY: If a crewmember inspects or touches the tire or wheel before the SRL Official inspects it, or observes directly, it will not be an approved tire change, or if the tire has sufficient air pressure when inspected by the SRL Officials the tire is not approved to change and the team will suffer a (2) two-lap penalty for each unapproved tire change. Tires changed prior to inspection by an SRL Official will be cause for a (2) two-lap penalty per tire.
  4. Once under PENALTY for an unapproved tire change, you will not be eligible for the “Free Pass”/ “Lucky Dog” for the remainder of the race.
  5. Excessive tire wear, is not reason for an approved tire change.
  6. Any tire that is changed must be immediately presented to an SRL official, in which it will be impounded until after post race tech inspection.


Blistered Tires: If a tire is blistered, you can change the tire, then immediately present it to an the SRL Official, if the tire is blistered, you will still receive a one lap penalty per tire changed. If the tire is not considered blistered by the official, then it will be a two-lap penalty per tire.


Flat Spotted Tires: If a tire is flat spotted, you can change the tire, then immediately present it an the SRL Official, if the tire is flat spotted, you will still receive a one lap penalty per tire changed. If the tire is not considered flat spotted by the official, then it will be a two-lap penalty per tire.

Race Procedures: COLORADO 100


Initial Start:

  1. Double file, once the Starter shows the ‘one to go’ signal, cars need to be double file – positioned nose-to-tail.
  2. The front row must maintain “pace car” speed until they accelerate at the drop of the green flag.
  3. The drop of the green flag starts the race, the outside front row car must not beat the pole position to the S/F line.
  4. No passing allowed until S/F line – You may not pull out of line until the S/F line.



  1. All restarts will be double file with the exception of the final 10 laps.
  2. All cars one or more laps down restart behind lead lap cars.
  3. When the double up sign or directive is given, the leader will choose to start inside or outside.
  4. Everyone else will double up, odd positions on the inside, even positions on the outside.
  5. The leader of the race must accelerate to re-start the race within the designated re-start area. The leader sets the pace until he/she accelerates to restart the race within the restart zone.
  6. No passing allowed until S/F line – You may not pull out of line until the S/F line.
  7. Restarts within the last ten laps will be single file.



Yellow Flag:1. When the yellow flag is displayed the field will be “frozen”, hold your position and proceed with caution. DO NOT RACE BACK TO THE START/FINISH LINE. DO NOT PASS.

  1. Your restart position will be the position you were in when the yellow was displayed, as long as you were able to maintain your running position, or were in no way associated with the incident. Down cars positioned behind lead lap cars.
  2. If you are involved, spin, slowed or your progress is disrupted by the incident, you will be positioned where you rejoin or blend back into the field – NOTE: the incident must play itself out before the order is set.
  3. Any discrepancies in line up will be determined by Race Control or may revert to the last completed green lap.

5.All yellow flag laps count. Except after a Red Flag

  2. If a driver picks up positions after the yellow flag is displayed they may be penalized.
  3. Officials reserve the right to utilize the yellow to check cars that are suspect and are being considered for a black flag (leaks, smoke, sparks, etc.). After they are checked, if okay – they keep their position.


Red Flag:

  1. Stop single file in a safe manner – if a car does not re-start on it’s own, it may be pushed started and maintain position.
  2. NO WORK may be done on cars during red flag condition – unless authorized by race control.
  3. Positions will revert back to the previous completed green or completed yellow flag lap to set line up. Those deemed part of the occurrence that caused immediate red flag or cars that pit will be positioned at the rear of the field.

Technical Inspection Process & Guidelines


Engine Inspection

  1. Engines and carburetors must be inspected and sealed before competition.
  2. The engine must be cold. Engine inspection will take place prior to the first practice.
  3. If your engine requires an inspection, please contact the series prior to the next race.


PreTech (refers to any scheduled tech inspection prior to Qualifying Tech)

  1. Teams must identify their crew chief for the purposes of discussion of any tech issues.
  2. All cars must go through Pre‐Tech inspection before the designated cut off time at each event.


Qualifying Tech

  1. All cars must go through Qualifying Tech in order of qualifying. If you miss your qualifying attempt by more than three positions, you will receive the slower of two laps. If you have a mechanical issue, notify an official.
  2. Each team must have an air filter at the tech trailer 45 minutes before Qualifying Tech opens.
  3. Once Qualifying Tech officially opens, all cars are required to be on the ground ready to roll to tech line. Remain in your pit, until an official directs you into tech line.
  4. Once cars enter the tech station, cars may not be lifted, tugged, or adjusted in any manner unless instructed to do so by an SRL official.
  5. Remove the hood and air cleaner to enter tech, then replace hood after tread width is checked, before going onto scales. No jacks will be allowed after air cleaner is installed, or as directed.
  6. Cars should not exceed 28lbs of air in right side and 20lbs in left side tires for tech inspection.
  7. More than two attempts to pass through Qualifying Tech will result in “Tech Line Probation”.
  8. Air pressure and tape are the only change that can be made to the car after Qualifying Tech.


Tech Line Probation

  1. Any team that has to make more than two attempts to pass through Qualifying Tech inspection will be put on “Tech Line Probation”, and will immediately be penalized by receiving the slower of two qualifying laps. You are required to take two green flag laps if you are under penalty, or you will receive no time.
  2. More than three attempts to pass through pre-qualifying – no qualifying attempt will be allowed.
  3. Repeat infractions of any tech specification or policy may also result in “Tech Line Probation”.


PostQualifying Impound

  1. After qualifying all cars will be impounded on Hot Pit Lane, then pushed into starting order and remain untouched (tape and tire readings allowed) until 15 minutes prior to start of race or as directed. All teams remain along Hot Pit Lane until your car is pushed in its starting position.
  2. If a car has a mechanical issue, not related to set up or handling, the team may be granted permission to pull out of impound to work only on the mechanical issue described, and start at the rear of the field.
  3. If anything safety related happens during qualifying officials reserve the right to let teams fix that item.
