Severe understeer

Ty for this info. A lot of great posts in this thread but this is the one that literally saved the game for me. Game feels so much better now. Thanks again!

my current tactic is just holding the gas and ramming into the concrete barriers so it corrects my car into the direction toward checkpoint… it’s kind of boring but AI physics and mine arent the same, they are stuck to the ground and can do perfect turns really fast. If I brake carefully they just pass me… idk car spins all the time AWD

Agreed, running a super downforce setup on a Centenario, 250+ the car is planted round anything. As soon as I go under breaking (heavily) or want to turn a corner anything from 100MPH or under, say 50 is a good example, I am always finding myself tapping the handbrake just to get the back end round the corner without the front tyres digging into the tarmac and not turning at all.

Could be me just not braking straight or early enough but at the same time it seems to last indefinitely, whereas the A.I are just on rails around the corners, wouldn’t be surprised at all if the A.I are not adjusted to my car setup (sim, no traction control, no stability) etc and just have it all on all the time the way they take corners against me.

What I have found so far is that:
Brake upgrades seem to add a bunch of braking stats but don’t do anything, and that trail braking will lead to catastrophic understeer.

Oh, and drivatars on unbeatable have infinite levels of grip and depending on the car, more power.

Adjusting your brake bias more towards the rear can help with trail-brake understeer. But don’t overdo it, or you’ll spin out.

I can put brake bias 100% to rear and still understeer… however handbrake throws the car into a drift. both of those should act exactly the same

That because your doing 100% to front, they switched it around.

What are these “brakes” people keep talking about?

The brake slider in the game is around the wrong way…not that I use race brakes very much at all.

To fix the understeer in the game reduce front Anti roll bars by 90% of the default setting and the same with decel diff.

Also add negative camber so you are at least in double figures on the front and a little less on the rear.

There is NO inherent understeer in the game once you have tuned the cars properly using the same theories that have worked in the previous games.

Unbeatable AI is definitely not unbeatable, but for the game to be a bit more playable, I turned off damage. Can win one out of two races.

Aerodynamic down force is… dynamic. If you’re doing 200mph, you’re going to have lots of downward force… if you’re doing 50mph, it’s likely you’ll have almost zero downward force.

Stand in your living room and hold your arm straight out to your side then alternate rotating your hand between palm up and palm down. Notice anything? Now get in a real car and open the window at highway speed then put your hand out the window and do the same thing. Notice anything this time? Turning your hand in your living room did not force your arm to raise or lower on it’s own… but the same activity at 70mph forces your arm to go up and down on its own. This is whats happening with your Lambo when you can’t turn at low speeds.

You’ve tuned your car for high speed grip without doing any mechanical tuning adjustments to provide low speed grip. If you’re having to tap the E brake to swing the back end out in order to enter a turn, then you need to fix your turn in response or your mechanical (not aero) corner grip. ARB (Anti Roll Bar) adjustments, as mentioned many times in this thread, can help with that but so can brake bias, camber, toe, spring, AND differential adjustments.

I’ll say it again. Front ARB settings are crazy high without tuning.

Typically in FM6 the front ARB started in the low to mid 20s. A lot of times a few clicks to the left were all you needed. In FH3 the front ARBs start at around 35. Unless you’re running really high rear ARBs (like 40ish) your car is going to understeer.

Come on folks. I can’t be the only one who noticed stock ARBs are a laughable 35/20.

I noticed.

I don’t have understeer problems. Just trying to stop that last bit of losing the back end.

Yep the front ARB settings are stupid high. I would call it laughable. I was chatting with a buddy that was complaining he couldn’t steer any of these cars and I walked him through doing a quick tune and explained a few things to him. I think I’m getting a Christmas present this year now lol. He couldn’t believe how much fun he was having and how all the cars were enjoyable after a little bit of tuning.

For a lot of people they don’t understand the tuning parameters, they can be very confusing. If any of you guys are new to this and want a little bit of help I recommend getting the forzatune app for your iPhone or Android based phone. The current version is Forzatune 6 which works for Forza 6 and Forza Horizon 3 as they use the same physics. You will still have to do a little tinkering based on each cars differences but it makes a big jump for a start

Front ARB?

In my S1 900 SRT Viper, softening the front springs some has helped with turn-in, I’ve found. But nothing, and I say nothing can help this God-tier AI that’s in the game right now. That needs a massive nerf. I spent one hour on a street race last night because without fail, I always got walked by first and second on the final drag. No matter the car I chose, no matter how much I drafted and stayed close, when it gets to the last section, they pull away as if they have nitrous.

EDIT: Nevermind on the opener. It just clicked.

Guys,

The PC version has horrible horrible input lag at anything under 60fps. It makes all the cars behave like tanks. No amount of tuning or controller settings can fix it.

I’ve been in tail happy counter steer heaven in FH3.

The only thing I tune at this stage is the diff in 2WD vehicles and occasionally on AWD.

That will change when I start building cars after I have done all the races and obtained most of the cars.

I just drive around each car’s natural tendencies to get the tail around /shurg.

IMO the Horizon games have a VERY realistic physics model, but with VERY UN-realistic amounts of grip. The cars do just about everything a real car would do, they just do them at much higher speeds than IRL.

So, all the things that apply to real driving also apply here: proper corner setup. Brake in a straight line. Be in the correct gear. Use throttle appropriately.

Braking while cornering = understeer.
Too much throttle on entry = understeer.
Carrying too much momentum mid-corner = understeer.

Horizon is not an “arcade” game, but neither is it a “sim”; it is “simcade”. It FEELS like an arcade game, with its soundtrack, flashy lens flares, party atmosphere and zany racing, but many real-world driving techniques still apply.

Thats completely not how a real car works, braking at corner entry or mid corner will always cause oversteer irl. shifting weight to the front wheels by applying brakes before turn in or trail braking to help with rotation is common practice in a normal car. only cars like audi’s or something thats prone to understeer will understeer under throttle or excessive mid corner speed. but that can be easily tuned out with toe and camber adjustments. Not one setting in this game improves my cars handling, i need to almost come to a complete stop before the car will turn… otherwise understeer, and not slight understeer like you need to just play with the wheel a bit and decel to correct, i mean plowing straight through the corner with 0 turning.
idk if its just my game or what, but i cant turn a car… all cars go straight unless i almost stop.

I agree 100% with op.

The cars feel great on dirt and poor on tarmac.

I’m a big forza (and PGR) fan and have always enjoyed normal track/street racing games but never liked any rally game. Now with horizon 3 i actually prefer the dirt tracks and i have avoided Surfers Paradise almost completely.

To make matters worse there are certain areas/corners in the game where the cars are noticeably worse than others. I spent a silly amount of time rewinding on one of these corners in the city trying all different approaches and even different class cars and the result was always the same - huge understeer.

For the record, i created a thread discussing this very issue 3 hours after the game’s early access release which was inexplicably deleted by forum mods.

The handling feels just right to me. Its the same as any other sim I’ve played. I have to brake properly and at the right distance just like you should in real life. I really like the handling in this game.
