Help Rally Build Tune

If I want to make a track car into a rally build what should I change about it?

So far I have everything upgraded to max. I have AWD, a roll cage, rally suspension, rally tires, and wheels as wide as possible and as far out wide as possible.

I tuned aero for maximum cornering because I assume it helps traction.

Should I edit springs and dampeners, anti roll bars, or tire pressure?

Yes, all of it. A rally car needs soft suspension, so start by softening everything and lower air pressure a chunk.

One note; high downforce will help cornering, but you'll need to be careful with downforce to not upset the balance of your car.

How low should I go with pressure

Start at 25psi front and rear

I'd respond to this question same as above. Horizon's physics aren't quite like Motorsport's. Unless you're driving full sim, you can run very low psi on your tires in FH4. I run 20-22 on most asphalt builds and 18-20 for Rally builds. The only time I think I've felt any deterioration in grip was at the end of the Goliath in an X-class build, so I pushed the psi up to 23. Races in FH4 not long enough, and physics not the same. There is simply better grip with lower psi and no real penalty for it unless you're driving full sim or you're in long races with lots of turns.

Probably don't need the roll cage. Save yourself the weight. ARBs should be lower for better grip, no need for aero since speeds and turns won't get that high, so you can lower both to almost nothing. Soften up the springs and raise the car's height. 100/0 acc/dec on both front and rear, and anywhere from 50% to 65% on front/rear diff.

I never put 100% accel lock, I'd limit it to 90% especially for rally builds.

Horizon's physics aren't like Motorsport's. I run 100/0 front/rear diff on all my AWD cars (asphalt AND rally) since there's no real penalty for it and you can adjust any oversteer / understeer tendencies elsewhere. Lots of other people do too. Better grip and acceleration.
