Is there any way to get the AI drivers to upgrade their cars in free play?

Okay, maybe I’m dense and missing the blindingly obvious here, but I can’t for the life of me figure out a way to get AI drivers to upgrade their cars in free play. I thought the obvious way was to add a second bucket, make sure “allow upgrades” is set to “yes”, then select a car or range of cars for that bucket and set it to the class or PI value I want - but unfortunately that doesn’t work at all. Whatever options I set in the advanced options, AI drivers seem to be limited to either homologated (if I specify a division) or completely stock (if I specify anything else). I find this severely limiting because it means I can’t run even slightly upgraded cars (or even stock race cars that have a restrictor plate to meet their division’s restrictions) against a somewhat realistic field of opponent cars. Doing a period-appropriate race tune of a 53 Corvette or a 328 and testing it against a field of similarly upgraded cars of the same type? Nope, not possible. Removing the restrictor plate from the 935 and driving it against 1970s race cars of comparable PI value? Also not possible. Doing an engine swap in the Isetta and running it against similarly crazy 2CV and 360 builds? No way at all. In many cases, the only way to use upgraded builds in free play seems to be to set the car class to ANY, but that’s not what I want - I want to run my vintage racers against appropriate opponent cars, not against modern Lamborghinis and 90s Formula 1 cars.

So far, I quite liked the homologation system and enjoyed the added challenge of finding the best combination of upgrade parts that meets the division restrictions, but if there is indeed no way to get opponents to upgrade their cars, I hereby join the ranks of people asking for a way to disable homologation in free play and give us back an option to make AI drivers upgrade their cars to something close to our car’s PI value. Not in career mode, not in mutliplayer, but in free play. Because seriously, which of the two words “free” and “play” didn’t Turn10 understand?

You’re gonna have to be a little creative with the restrictions unfortunately… For example, the smaller cars can easily be restricted with a maximum weight threshold and model year.

I wanted to race homologated and restricted by region, but this is not possible. So I’ll keep experimenting with it and see how far I get.

Someone in GTPlanet was able to single out the Group C/IMSA GTP cars, complete with no restrictor plates, but that’s a bit easier than to do what you want.

I do know that class restriction is not the ideal way to set up a race, because if you pick a class, the game will only allow cars which start INSIDE said class. If you use minimum PI, the game will not allow you to use cars with inferior PI as stock but which can be pushed further than that. However, the classes are all based on PI so if you specify maximum PI of 500 you’ll have only up to C class no matter what.

Remember that in your failed attempts you were indeed disabling homologation, but the options aren’t intuitive enough for us to nail the restrictions at first.

Thanks for your tips - I have already figured out methods of getting the AI to drive the cars I want to see as opponents, but that still doesn’t solve the issue that the AI never upgrades cars. I have literally spent another two hours this evening trying every possible combination of the advanced options, and the results were always the same - AI cars are either homologated or completely stock.

To stick with one example, I have a BMW328 build with a PI of roughly 550, and I’d like to drive it against a field of 328s that are also upgraded to a similar PI value. Whatever I do, I will either be alone on the track or have stock E214 328s as opponents. If anyone can figure out a way to do that, please tell me how…I’ll be eternally grateful.

I must say I’m in the same boat, haha. I tried to create a 1987-2002 touring car race without much success, but for my event the restrictions are more complex.

Have you tried restricting it by model (1939 BMW 328), allow upgrades to YES and maximum PI of 550, with everything else as default? That’s how I’d do it.

Yes, that was what I expected to work - unfortunately it doesn’t. If I do not set a lower limit for PI, the opponents will all drive stock 328s with a PI of 214, if I set a lower limit of 530 or something, I’m alone on the track because the game thinks there are no eligible cars for my opponents. I also tried not setting up a second bucket and just setting car restrictions to 328 only, upgrades allowed, no lower limit for PI, but that also leaves me alone without opponents.

The really stupid thing about this is that the code for opponents to upgrade to match my PI is still there, but there’s no useful way to trigger it - in the case of the 328, you can set the division to Forza Specials which allows you to upgrade to whatever PI you want - and if you do that, the opponents will happily upgrade their cars to match your PI. The problem of course is that then you have to race your beautiful 328 against delivery vans and trophy trucks, which is kind of immersion-breaking.

I actually wish we could give the AI the tune we are using, that’d be interesting and fix a lot of problems with Spec races.

This is where you kinda scratch your head at T10 where they could have easily simplified the freeplay settings. I’m actually looking for the opposite, racing cars against each other in stock form. Every race it seems like every car has similar PI which obviously means they are homologated. I don’t get why they set this up like this smh
