TORA Britcar 24 Hours of Silverstone - Rules and Regulations

Welcome to the TORA Endurance Championship, a four rounds series of full length endurance races designed to test both you and your team to the limits. For three years now we have run full length races of both the 12 Hours of Sebring and the 24 Hours of Le Mans. This year will be no different, but we will also be visiting Silverstone and the Nurburgring along the way.



The third event of the year is the TORA Britcar 24 Hours of Silverstone which takes place on the weekend of the 15th and 16th of September.

The race will start at 2pm BST on Saturday the 15th and end at 2pm Sunday the 16th.

Teams can consist of up to 4 drivers. Ideally you want the full four to make the 24 hours less challenging on yourselves and your consoles. Teams must drive in the same car throughout the event. If any team members switch into different cars throughout the race then their session will not be counted in the team's overall distance. Drivers may enter as individuals who feel that they are up for the full 24 hour experience or just want to take part an a couple of the stints throughout the day.

The race will be split up into twelve stints that will last two hours. Each stint will be competed by one driver from each team, so you will not be racing on track with your team mates during the event. Driver changes take place when the stint is over at the 2 Hour mark, where we will then go back into the lobby and the drivers and lobby hosts will change over. At this point the host will enter the distances covered by the drivers into the database which will be combined for the final results at the end of the race. The race will be scored on "distance driven" where bigger is better. To accomodate for the stint changes a 15 minute turnaround will be applied for 'a pit stop with driver change simulation' so in reality the stints only last 1 Hour 45 Minutes. The final stint will be a 2 hour race to the flag, just like we do in the ISCC. The timer however will be extended by 15 minutes so we can record the distances traveled, so basically the final stint is 2 hours instead of 1 hour and 45 minutes.

The first stint will start under a Rolling Start following standard TORA procedures. The lead car will take the grid around at 80mph Maximum and will then slow down to 60mph for the last section of track where the cars will line up 2x2 in their qualifying order. For the remainder of the stints the races will start under a 'Random' grid and will be set to a 1 second roll off delay to prevent first corner pile ups.

Unlike previous events we will not be following any real life safety cars or incidents. Saftey cars will not factor into the race as the entire event is based upon your endurance. If there is a crash you will have to recover and continue to the end of your stint and deal with any damage that you pick up. This should be incentive enough to stay out of the wall. Damage will be set to Limited to replicate fuel and tyre wear.

Qualification for this event will be held throughout the week leading up to the weekend. Each qualification round will last 45 minutes and drivers will not be allowed to use the sessions as a practice. The team will qualify as a whole, so out of the 4 possible times that could be set by the entire team then the best time will be taken. For example, if Driver 3 sets a better time then Driver 1 then Driver 3's time will be taken as the best time. Each driver may only compete in one qualifying session. There will be lobbies hosted throughout the week to accommodate racers in European time zones and American time zones.

There will be one mandatory pit stop per session.

Settings
- Collisions will be set to off during all Qualifying sessions.
- Collisions during all races will be on.
- Damage will be set to limited.
- TCS, Driving Line and Normal/Simulation Steering are the only allowed driving aids that may be used. ABS, STM, Auto-brake and Auto-gears are prohibited. Manual gears must be used but it is up to the competitor if they wish to use the clutch or not.

There will be mandatory Numberboxes for the Britcar event, and these will be distributed when requested.

Car Numbers

Each competitor in the team must be registered with TORA and have a TORA Race Number. This is for admin purposes only. The number that is displayed on the car during the 24 Hour event must be one of the competitors TORA numbers who is present within the team. Whichever driver's number the team uses is up to you.

Race Rules
Safety Car Rules
There will be no designated ‘safety car’ vehicle utilised in our championships. Due to the limited nature of online race lobbies. However TORA does operate general safety car regulations which provide a similar outcome, utilising the lead vehicle in the lobby to slow the cars to a safe speed whilst any obstruction is cleared from the circuit, or allowing affected competitors to repair any damage and catch up with the rest of the field.

When the Safety Car Is Used
The Safety Car will only be deployed if an incident or incidents occur between two or more competitors that severly impairs both competitors race. Only a driver involved in the incident may request the safety car, and make the request to the Lobby Captain. The Lobby Captain may seek the opinions of other competitors, before making the decision to activate the safety car period.

The Safety Car may not be requested during the final two laps of a race.

Forming a Safety Car Period
In the event of a safety car period being called, the lead car takes the role of the Safety Car or Pace Car. The Safety Car must not exceed 80MPH and the pack must form in current race position in single file.

Conduct During Safety Car Period
Drivers involved in the incident should form at the back of the pack, in order of relative position before the incident, unless there is an obvious instigator. Competitors must keep a reasonable distance during the Safety Car Period. Brake testing during the Safety Car period will not be tolerated and may lead to penalties, either race meeting or championship. Warming of tyres is permitted but must be undertaken in a safe manner with due consideration given to other competitors. Competitors who leave the track by their own volition during the Safety Car period may be passed by the rest of the pack and the competitor will form at the back of the field.

Drivers not involved in the incident may pit during a Safety Car Period, but will become resume the race at the back of the field. If the grid has not formed by the time the pole sitter reaches the pit lane entrance, the safety car may continue for another lap. It is YOUR duty to ensure the safety of your fellow competitors.

The rules and regs haven't been uploaded to the website yet, it was a temporary holding page until we were ready to announce the rules. Everything will be finalized by the end of the weekend.

Ok thats cool just wanted to point out incase a mistake

hey just pointing out that the 2000 Nissan Silvia Spec-R comes stock with 250HP. I have been wrestling with the build cause its a car I would possibly drive and finally got everything legit except for the 1 HP i am off... is this a typo or am I missing something?

The 250bhp is the absolute limit, but we set it to 249 to make sure people would safely build their cars to fit the lobby settings. Some cars run at a stated 250bhp but run at about 249.xxx and still fit in the limits. Some cars state 250bhp but run at 250.xxx and don't fit in the rules limits.

Tomorrow I will remove any cars that do run at 250bhp, to make sure there are no conflicts.

I know that each member of a team must be registered with TORA but do they have to be registered when entering in a team ? cheers

Hey Gunner,

Yes they will, the whole team needs to be registered.

Does each driver have to be registered before I can register a team ?

Just as a heads up, the Clubman specs are different in the 'Car List' and 'Rules and Regulations' threads.

Cheers Luke, updated.

Am I going mad? I thought there was an allocation of 3 cars per team? It say's edited this morning on the post? Has it been increased to 4 or was it 4 all along?

It was bumped up to 4 car allocation last week.

I've been flapping for nothing lol

Can you have a car livery that is different colours on the left and right hand sides circa the BAR in 1999 when they wanted to run 2 separate design chassis but had to amalgamate them into one?

I see no reason you couldn't do that.

How does the start of a stint work I understand the rolling start for the first stint but how does it work after that?

It is set to highest PI first order, and then a 1s delay between starts from the grid. This is the best way we can do it, and is effectively a safety car restart after a pit. When cars pit during Endurance races they may or may not be in front of the cars that were in front of on track, so that is the best way to think about it if your PI puts you behind a car you were in front of. At the end of the stint the distance is recorded to the mile so you don't lose any advantage over them.

Does that mean the same car will always start first :/

thanks that sounds good to me just wanted to know so I was prepared and can pass onto my team

Would the grid set to completely random not be more fair rather than the same team getting and advantage even stint?

Could be, I wanted to do it by team but it has to be by group, so the way we have the 15% in it would mess it up. Random would be good, but a 1s start may not be enough if a Clubman is in front of a TGT car.

it can run a 1 second roll off , in buckets right so TGT are allways first i think ?

Yeah but some TGT are not 15%, as are some Production. Random would be better with a 2s roll off.

ahh yes i see your point now
