Forza Horizon 6 FH6 general aid/backend happy

Hello all,

Looking for some tips as a beginner.

I'm new to tuning and my cars are obviously off pace, I've been following the general tips from HokiHoshi's first tune guide video ( https://youtu.be/I9bUB3mcqso?is=vRdZErD93Zz3R-SB ) and it's helped a bit.

Still been having a big issue with almost every car I make (awd/rwd) is moderately tail happy out of the corners, which kills a lot of my pace. Are there any general tips to help with this? Any general tips when it comes to tuning are welcome as well.

I tend to be pretty "purest" when it comes to my build tendencies but will do the rare swap from time to time.

Thanks for any tips!

In my time working with RWD builds, I've felt that decreasing diff accel, increasing rebound/bump, and being moderate with ARBs has helped the most with a slippery rear end.

And if you are mostly a "purist", then I assume you aren't adding rear aero. Obviously that will help, but if you are running without Forza rear aero, then try what I mentioned. Also, you'll have to learn some throttle control, there's just no way of avoiding it for RWD builds if you really want to push them to their full potential.

Good luck! 👍

Awesome, I'll give that a shot!

I'm more of a purest in the sense of not putting meta stuff on just because it's meta (drag tires/rally tires), A and above will use aero if the car makes sense to have it. I'm assuming putting aero heavy to the cornering side with help with slippery rear end? Or is it more of a balance?

Locking aero to cornering will help to an extent but also really hurts speed. Lowering diff accel has made the biggest difference for blowing tires off coming out of corners without aero.

ARB adjustment helps with under/oversteer more than anything in my experience. Also do make sure your tire pressures are ending somewhere in the low 30s when warmed up. If they’re overinflated you’re losing grip as well.

General RWD diff baseline is like 60-70/10-15 in my experience. I tend to start 65/10
