We did Trans-Am cars last season, now it’s time for something a bit more modern. Introducing the Fourza Grand-Am Series!


Car Rules and Specifications:

Unlike our Trans-Am series where every car had the exact same upgrades across the board to start out with, the initial upgrades in this series will be specific to each car to ensure parity amongst the field is as close as possible prior to tuning and balance-of-performance adjustments (all cars in the series lap within 1.3 seconds of each other at Mugello and hit between 146-157 at the end of the main straight). All cars will be initially built to A600 (or thereabouts depending on the rims you choose) and the list of eligible cars and their required upgrades is as follows (all other components that are not explicitly mentioned are to be stock):

- Engine: This Camaro uses Forza’s twin-turbo swap glitch to be eligible for the series.

You should now have a naturally-aspirated 465hp ZL1.

*DLC cars

As Corey pointed out, I somehow forgot to include race transmissions in any of the cars’ required upgrades list; if you wish to use race transmissions you may do so by removing an engine upgrade to compensate for the increased PI, do not touch any of the handling upgrades. In the case of the Boss 302, M3, Challenger, Maserati, and ZL1 (which have stock engines) you can remove tire width.

Balance-of-Performance Adjustments

While those aforementioned upgrades are required, depending on what kind of times you set your car may feature more or less upgrades thanks to balance-of-performance adjustments. BoP adjustments will work same as they did last year: I post a lap time in the week prior to the race, and you take your A600 car out for about ten laps and see how you compare; if you’re lapping faster than the time I posted, remove some upgrades (starting with tire compound and width so you can still keep up on the straights) and if you’re slower, add some (preferably saving engine upgrades for last). The ultimate goal is to meet (but not exceed) my posted lap time.

I would also like to add a caveat to this section of the post: BoP adjustments should only be used as a last resort and are not a substitute for practice. The point of this series is to give everyone a chance to win regardless of skill level but it’s not fair to the rest of the field to have someone who put minimal effort into practice and tuning show up and blow their doors off with a huge power handicap (often times lapping two or three seconds faster than the field once they figured out the track). Other racers got really vocal about this towards the end of the season so this time around I’m going to have to be more adamant about lap times.

I promise you will enjoy these races more if you actually put in the time to get better instead of using BoP adjustments as a crutch; you’ll post more consistent lap times and will be racing with the pack the entire race instead of passing everyone on the straights only to lose position because you don’t know how to take the next corner. Spending just fifteen or twenty minutes after work or school for a few days during the week can really make a big difference.

Race Info:

Time:

- Since it seemed to work well last series, the lobby will open at 4pm EST on Saturday and races will begin no later than 4:30. Races will again last around 45min-1hr depending on what track we’re at that week and we could do endurance rounds at Road Atlanta and Le Mans if we all want to. If Saturdays don’t work for you another Opponaut (who I’m not sure would want me to share his post because it’s not finished) has a very similar alternate series in the works that will be on a different day so you can still race.

Assists and Damage/Tuning:

- Like last series, all assists are allowed but again we encourage you to use them sparingly. You can take a lot of time off your lap just by learning to actually drive the car instead of relying on electronic help to guide you around track.

- Damage and fuel and tire wear will be set to cosmetic only. Please avoid contact at all costs regardless.

- Tuning is not only allowed but encouraged; we’d prefer you spend time tuning your car as opposed to just throwing BoP upgrades at it. Scorpio GTX1 posted a great tuning guide here if you’d like to learn how to set up your car.

Grid Ordering:

- To be fair to everyone starting order will be randomized.

Scoring:

- This will be a points-based championship series. Scoring is as follows: 16pts for 1st, 15pts for 2nd, 14pts for 3rd, 13pts for 4th, and so on, with 16th receiving 1pt. In the event we don’t have 16 racers we will score to the lowest position (e.g., 12 people so last place gets 5pts). DNF’s will be counted as your final finishing position so if you get disconnected or have to leave suddenly you’ll still get some points just for showing up.

- In the unlikely event that more than 16 people try to join a race, the lobby will be filled on a first-come, first-serve basis and anyone who doesn’t make it in won’t be racing for points that week. Sorry but we don’t play favorites or save spots, so be on at exactly 4pm EST when I send out invites.

- I’ll make another Excel spreadsheet so all you have to do is show up on Saturdays and race. Finish the season with the most points and you’ll get a shiny new Fourza Grand-Am Series trophy:

Race Schedule:

Because I was lazy and only just now got around to making this post this season will be a bit abbreviated compared to the prior series, though only by a few races. You’ll notice these races take place every two weeks; like last year, we’ll be running an as-of-yet-undetermined series concurrently with this one that will take place in the off-weeks of this one. Order is not entirely final and is subject to change:

7/11: Sebring

7/25: Infineon

8/8: Road America

8/22: Le Mans

9/5: Maple Valley Raceway

9/19: Sunset Peninsula Raceway (reverse)

10/3: Road Atlanta

10/17: Mugello

10/31: Sedona Raceway Park

11/14: Circuit de Catalunya (National Circuit)

11/28: Laguna Seca

12/12: Nordschleife


Everything Else

- If you want to join this series but aren’t already in the Oppo car club, mention that below and I’ll send an invite. We send out invites from the club screen on race days so if you aren’t a member you won’t get one and thus won’t be able to join the lobby.

- I will again remind all participants that while we expect everyone to follow proper racing etiquette you’re going to have to be OK with the fact that contact will happen no matter how hard we all try to avoid it. Having the cars be as fair as they are means you’ll constantly be in traffic and battling for position and a bit of rubbing will be inevitable, as will more serious incidents. There will be races where you’ll get knocked off track or spun out by no fault of your own and you’ll end up finishing in the back of the pack that week; anyone who’s raced online will know that’s just a part of the game and these series will be no exception.

- That being said, there’s a very fine line between incidental contact (tapping someone’s rear bumper under braking, running a bit wide through corners, etc.) and aggressive and dangerous driving (divebombing corners, running people off the road, deliberate contact, etc.). Please don’t do any of that, drive smart and drive clean and we’ll all have fun racing.

- All relevant information (including pre-race, post-race, and other miscellaneous posts) will be posted at around 6pm EST here on Oppo and tagged ‘Fourza’; I hope to get my post-races up the following Sunday or Monday and have the pre-race post for the next round up around the same day the week after. For the first few rounds of this series I probably won’t be able to reply to any immediate comments or questions thanks to my work schedule but I’ll get around to them as soon as I can (this shouldn’t be a problem once I go back to school in late August). Any other questions just post your own thread to Oppo using the same tag or reply to us directly and one of the braintrust will eventually get around to answering you.

- RoboRed will be streaming races again via his Twitch account so even if you can’t race with us you can still watch the action. Be sure to check out his own sports car series too.

- That’s about all I got this time. Series starts in exactly one week so bookmark this page, go build some cars, and get practicing. We’ll see you out on track.
