Hey guys
I’ve been playing Forza for the past month after no really ever being into cars. This game has captured the attention of myself my friends and my son…
I have been playing with a tuning setup for my Ferrari F12 and seem to be having some issues settling the car.
If i post the specs of my tuning would you guys be able to give me an idea what i need to change?
FYI i picked the F12 because it’s one of my favorite cars next to the LFA
okay, here are the stats
the car has been optimized for S class racing. Here are the tuning stats

any advice would be amazing, as i said before this is my first attempt of a tuning and i had it pretty good at one point, but the back end was throwing out under heavy break, this was my attempt to fix it.
cheers for taking you’re time to help.
Yeah Pro just post the build and what tune you are running and im sure we can give you a hand in helping you tune it
Okay above you will find the tuning set up for the Ferrari f12
I will have a look in the morning and get back to you.
I’ll try to build an S class and use your tune to provide feedback. My S-class build will obviously (most likely) not be the same. I noticed you went AWD, any particular reason? What tracks are you planning to run the car? Thanks!
I went awd to improve traction, as I use Mt panorama as my test circuit I wanted to make the car handle the sharp turns at the top of the mountain.
Thank you guys 
Hi Protossjr,
First of all, you’ve pulled together a pretty good base tune for this being your first one (if I understood/inferred it correctly from you OP). On your OP you mention having “some issues with settling the car”…it be good if you can describe the set of issues you have run into your current tune for your driving style.
I did a couple of things, since I did not know your particular build, I first tested your tune on a build that I pulled together. If you are interested, I can PM the build information to you. Here is some general feedback on your tune, assuming build “closely match”, and, per my driving style/preferences.
For the other settings, again, just some additional preferences:
I also have a tune for the build I came up with which I can also share. Just let me know.
Hope this helps!
Mate that is incredible, thank you for the compliment it means alot to me.
I used the optimum auto set for parts as the sports tires offered more grip but took me to r class.
The issues I am having are the rear understeer and its willingness to slide off the track on a sharp turn.
Also I find that my rear looses traction under full breaking at high speeds.
I am considering re building to parts base to incorporate the twin turbo though my car maxes out at 330 km/h I wanted it to respond to turning more.
Cheers mate
For you braking into corner issue. Not sure if you are aware of this but the brake bias is backwards. If you have 45% rear brake it is actually 55% front brake pressure. I usually run between a 53% and 55% for my brakes non abs. If you run abs a lot of people have good luck with a 51% bias and 110-120% brake pressure.
Is the rear end of the car sliding out on corner exit as well?
Also please pm me you’re spec, I would love to see how you did.

Protossjr - just sent you a PM w/build & tune. Feel free to modify per your style. Good luck!
On your issue (braking), Johnson just provided some good advice above. Plus, check the ARBs as well. If corner exit on throttle, it could also be a Diff setting change required.
If your main issue is the rear end under heavy braking, follow Johnson’s advice and add front brake bias. When you brake, the weight is transferred to the front of the car so it makes sense to have more brake at that end of the car. I usually run 55-60% front brake bias or until the rear brakes do not lock up under heavy braking. Then I dial it back towards the rear a percent or two. This is preference as I like to trail brake into the corners and if the front brakes are busy slowing the car down they are less responsive to turn.
Ill certainly give it all a go once I get a chance to run tests.
Is there a way we can record telemetry? I would love a gauge that tells me coldest/hottest tire temps, spring strain etc.
Use the “Record That” function of the Xbox One. Record the video than edit/play back. Other “normal” racing video replays do not have access to the telemetry info, even if you do display it while racing.
If your talking about live telemetry you can simply push up on the D-pad and with the pad move left or right to look at the different telemetry.
With this game it’s all about the build of the car and what it’s meant for, for example are you looking for an all out grip tune, a speed tune? In some instances you can meet in the middle, but the car may not be suited for most tracks. As far as your initial tune goes the main thing that jumps out right away is the rear camber, as stated above you always want negative camber and in FM5 its much higher than what it has been in the past. Determining how much camber to use, i base off of how wide the tire is, the wider the tire the less camber. But from what I’ve seen I’d say the lowest I would ever go with camber is -2.0* depending on the track it’s being run on. Now, as a rule of thumb, if your rear end is giving you the trouble fix the rear settings, there’s no need to touch the front if that is doing what you want. Also for your dampening 13,13/1,1 seem to be the overall best balanced setting, it goes against what should be correct. Ride height lower it way down, your spring settings should be atleast around 500 depending in how heavy the car is and if your using LBS as the measurement. I’ll try to add more once I get home from work and have a little more info to go off of.
Mate thats all brilliant stuff.
It should be said that chatting with you all has majorly inhanced my experience in this game.
What I want to achieve is a build thats a great all rounder, I love the Ferrari f12 for it’s look and feel. Speed isn’t really an issue. For the most part for me as I max out on 320Km/H which is fast for s class. I want the car to stop sliding off the track on corners. Now after chatting I know that I need to adjust the psi, springs and camber. Will be honest though the rear camber was originally a test I never converted back.
The group I race with tend to focus on Mt panorama, spa, prague, and cerca del a sarthe. So I prefer my car to be running hard on that.
So with those tracks your build would be better suited as more of a speed tune, as most of the tracks you mentioned have long straights and sweeping corners. Also after your changes, and if the rear is still stepping out, your rear anti-roll bar should be lowered.
Let us know the weight of the car, and it’s tire width to help you further if needed.
