The Oppositelock Forza 6 2.4 Hours Of Daytona: Sign Up Post (CAR LIST UPDATED)

Illustration for article titled The Oppositelock Forza 6 2.4 Hours Of Daytona: Sign Up Post (CAR LIST UPDATED)

Now that the Oppo Endurance Championship is finished, it’s time for a one-off event to kick off the new year. So, I present the Oppositelock Forza 6 2.4 Hours of Daytona. In this post, I have all of the specifics, including time and eligible cars, for this race. You can also begin to sign up for the race in this post.



The race will be held at 4:30 PM eastern US time on Saturday, January 7th. I’m not doing a poll for the date this time around for two reasons. Firstly, this is the only date that I can actually host this race myself and/or have reliable internet. Secondly, the first round of the endurance championship was held on this weekend last year and was a good date for everyone since it is at the tail end of winter break. I realize that everyone has their own time that would work best, and I’m sorry if you won’t be able to make the race on this day. However, if this date is problematic for a large amount of people, the date can be moved, but I would like to avoid this scenario if possible.



Firstly, it is open to anyone and everyone. It doesn’t matter how good or bad you are at the game. We have people of all skill levels regularly race with us. It results in some great racing, too. These whole series, especially the endurance races, are some of the most fun I’ve ever had in Forza. Back to the race itself, beforehand there will be a ten minute qualifying session to set the grid. At the start of the actual race, there will be a single formation lap, where the field will form up, and the race will start when the countdown timer reaches a time specified by me during the lap. The race will be 2 and 1/2 hours long on the Daytona Sports Car Circuit. Yellow flag and caution rules will also be in effect. This is going to be a long race, but it will be handled the same way as any of our other races. Drive like you are in an actual race, and not an online public matchmaking lobby, and you will be fine. If you are new to racing with us or need a refresher, take a look at SVTyler’s post on driving etiquette. If you follow those guidelines, you will be just fine in the race. In terms of assists and lobby setup, damage will be set to simulation, collisions will be set to always on, and all assists are allowed. Also, while all assists are allowed, many of us use very few of them, mostly limited to driving line, manual without clutch, and the occasional ABS. Just something to keep in mind. Also, instead of using parties or gamechat, we are going to be using an app called Discord to communicate during the races. It is available for free on any desktop or mobile OS. Please join the Discord server even if you don’t have a mic, that way you can still hear everyone else. If for some reason we are not using the app or it fails, we will be using gamechat or party chat to communicate, and hoping for the best. HERE IS THE INFO AND SERVER ACCESS LINK FOR THE DISCORD SERVER.



We will be racing GT, Daytona Prototype, and P2 cars for this race. There will be a set build for each car that you must match. Since we are running two different classes, I want to make my own notes about driving etiquette. Prototypes should ALWAYS yield to GT cars. This is a reversal of what I had written for the endurance series, but after seeing how RORA did things with RLMS and that this is how it is in real life, I feel like this distinction needs to be made. However, seeing how people raced in the Oppo Endurance Series, I also don’t think that this changes much on how the races are handled. The LMP’s usually managed to find a way through GT traffic, and when it was one GT and one LMP, the GT just moved for the LMP, and that is still allowed and encouraged. However, now I want to distinguish that GT cars have the absolute right to hold and use the racing line when a Prototype is approaching/passing. That being said, if you are racing a Prototype, it is highly encouraged that you have a mic so you can warn GT drivers when you are going to pass. However, I recommend that you use a mic regardless of what car you are driving. If you are in a Prototype and stuck behind GT traffic, be patient and do not force your way through. The only thing that will happen if you try and weave through several side by side cars is a crash. Just in general, do not try a high risk maneuver. Be patient and let passing opportunities create themselves. Also, be careful when exiting pit road as to avoid oncoming traffic, fast or slow moving. It is probably a good idea to call out when you are exiting the pits so the drivers passing by them know there will be slow traffic coming up in front of them. In addition, it is expected that all drivers will follow and obey track limits. Track limits will be defined as the area of the track enclosed on either side by grass, sand, varying types of tarmac, or any combination of the three. Of course, accident avoidance overrules track limits and you can go off-road in that situations. Cutting corners sharp is also fine so long as all four tires do not exit the track. However, driving off-road to completely skip a corner to gain a time/racing advantage will not be tolerated. Additionally, driving backwards on the track is not permitted at any point. Driving backwards will result in a very probable disqualification if there is a major incident.


Qualifying is something new that I am trying for this race that will also be incorporated into future series. Before the race, there will be a timed race session with damage set to cosmetic and collisions set to always off for you to set your fastest time and determine your spot on the gird. Qualifying is not required, however not participating in it will immediately move you to last place in your class for the race start.

Here are the rules for cautions. Credit for the original rules goes to r/redditracing, as I’ve only made minor changes. For a caution to be called, a multiple car wreck must have occurred in which both cars either spin, flip, take significant damage, or lose serious time off track. One of the involved drivers and/or a witnessing driver must call the caution. When a caution is called, the race leader should slow to about 50 or 60 mph to allow the field to catch up as quickly as possible. The race leader will also assume the role of pace car unless there is a pace car present in the race. If there are multiple pace cars, the one ahead of AND closest to the leader will go in front of the field. ABUSE OF THE CAUTION CALL WILL RESULT IN SEVERE PENALTY. The caution will last one to two laps. The field should form quickly and efficiently to reduce length of yellow. There is no passing under caution with one exception. Any cars that are not on the lead lap may make ONE lap up under yellow (if you are multiple laps down, you can only make up one lap per caution). However, they may not pit to repair damage if they take the free pass. There is also no guarantee that a free pass car(s) will catch the tail end of the field before green. The pits will open as soon as the race leader is approaching the entrance. Cars that were heavily damaged in the caution may pit before the pits officially open, however they MUST go to the back of the field in their class for the duration of the caution. Restarts will be single file at the start finish line unless otherwise specified. At the restart, the pace car will enter the pits, and then return to its on-track resting point on exit. Once there are less than 5 minutes left in the race, no cautions can be called.



Listed below are the cars that are eligible for both classes as well as their respective build rules. If it is not listed, it is not eligible for the race. However, if you think I forgot a car or want to plead a car’s case, leave a comment on this post on why you think that car should be included. Also, no aspiration, drivetrain, or engine swaps are allowed unless otherwise specified.


To make the field more diverse and for better pictures, custom made or storefront paint jobs, and unique numbers for each driver are highly encouraged. It may be too difficult to organize everyone having their own number, but try and give your car a unique paint job to help it stand out. Also, if you paint your car as something that it is not, like painting the Mazda Lola as a Nissan Oreca, and want it recognized as such, please let me know or make it obvious in the design so I can name it as such in the post races. Otherwise, it will be denoted as whatever it is in the game.

Some Other Important Notes

  • I tested all of the cars extensively to make sure they were even. In addition, I will keep testing them up until race day to make sure there weren’t any inconsistencies in my original testing.
  • The build rules for any and every car are not 100% set in stone and may be changed at any point for re-balancing of the field. Do not expect changes the week of the race unless there is a major issue. All of this being said though, all of the GT cars were within 0.3 seconds of each other and the Prototypes speeds are balanced for their varying fuel economies, so at the moment I am not anticipating changing the builds unless their is a major development.
  • Multiple cars have power restrictions in place to ensure parity with the rest of the field. In the pre-race lobby, you will need to move to the specified handicap player bucket if you run a car with such a handicap. In addition, remember to keep the handicap in mind when tuning your car. Since I completely reinvented the wheel when it came to build rules, including the adoption of a combination of RORA and TORA’s GT build rules, power handicaps were unfortunately unavoidable. Thankfully, since this is a one-off event, you only need to remember to use an online lobby for testing for just one race.
  • Please note that only the 2011 version of the McLaren MP4-12c GT3 is allowed. The others are not included because of parity issues.
  • Custom rims are allowed on all cars so long as some rules are followed. For all cars, heavyweight/chrome rims (Dub, Lowenhart, etc.) are banned. Due to the build rules, the rims cannot change the PI of the car. For example, if the PI is R858, the PI must stay that way after the rims are added.
  • Special thanks to TheCowmaster for creating the builds for the prototypes that I used as the basis for the current ones and for all the testing he did with them before I had even confirmed this race was going to happen.

UPDATE 12/29/16: So after some requests, consideration, and testing, I decided to include the 911 GT1. Partly because this is just one race for fun and why the hell not, and partly because it can serve as a stand in for the new mid-engine 911 RSR. However, do to it’s age and oddity status in this group, I am limiting it to just 3 entries, one of which has already been claimed. So if you want to drive that car, please let me know as soon as possible. Also, I’m (belatedly) including a shout out to TheCowmaster for his work in testing the prototypes as he was working on builds before I had even confirmed this race.

The following cars are now eligible for this race: 1998 Porsche #26 Porsche AG 911 GT1 98


UPDATE 12/31/16: So I did some more testing with the 911 GT1 and it is capable of more than I originally thought. Gave it a bit less power but increased the handling to compensate.

If you are participating in this race, please click the link below to complete a very brief survey so I can keep track of who signs up and their gamertags (the only information required is your gamertag and Oppo username). There will also be questions asking what class you will be running in, if you are interested in being a pace car (though we already have someone who usually is able and willing to do that), and if you want the race to be run in day or night conditions. If you sign up and for whatever reason are not sent a friend request by me, feel free to send me one as well as a message indicating that you intend to participate in the race. My gamertag is Corey CC97. In addition, you can get in contact with RoboRed (GT: RoboRedMdn1te) or SVTyler (GT: mackleroy45) if you do not hear from me, and they will get you set up. If you do not complete the survey or get in contact with me or the other people racing somehow, there is a very good chance you will not be sent an invite to the race on race day.




I will be posting reminders for the race frequently with links to this post. If you have questions, please leave a comment on this post or one of the reminder posts.
