ACC Moza Settings: The R-series GT3 Recipe

I’m a sim racer and amateur racer with a passion for Motorsport, good racecraft and the technical and setup aspect of sim racing.

ACC on a Moza R-series base is, for my money, one of the best sim racing combinations going in 2026. Real-world GT3 steering geometry through a wheelbase that’s pound-for-pound the best-value DD on the market. The fact that you can spend less than the price of a decent set of pedals and end up with an FFB experience that’s 90% of what a Podium DD2 delivers is one of those quiet sim racing miracles. The setup, though, has a few specifically Moza-on-ACC calls that aren’t intuitive coming from AC or iRacing. This page covers all of them.

The headline calls: Wheel Damper higher than you’d think (25 on the R12 and up, less on the smaller bases), Road Sensitivity at 10 (high – because ACC’s road effects is real telemetry not canned), FFB EQ Flat (always – ACC shapes its own signal), and steering angle locked at 1080° in Pit House with ACC’s soft-lock handling per-car. The headline mistake: leaving Hands Off Protection on, which occasionally drops FFB mid-corner in ACC for reasons nobody has fully explained.

Pit House setup for ACC

Moza on ACC needs more Wheel Damper than it does on most other sims, and it took me a while to understand why. ACC’s underlying FFB is heavier and more “Ford” than AC – more mechanical steering rack, less raw tyre slip. On a high-torque Moza like the R12 or R16, that heavier signal at speed creates straight-line oscillation. The Wheel Damper at 20-25 (versus the 0-10 you’d run on AC) absorbs the oscillation without dulling the cornering signal. R5 and R9 need less because there’s less torque to oscillate in the first place.

Setting	R5 (5.5Nm)	R9 (9Nm)	R12 (12Nm)	R16 (16Nm)	R21 (21Nm)
Steering Angle	1080°	1080°	1080°	1080°	1080°
FFB Intensity	100	100	100	100	100
Wheel Damper	15	20	25	25	25
Wheel Spring	0	0	0	0	0
Road Sensitivity	10	10	10	10	10
FFB Filter	6	6	6	6	6
FFB EQ (set Flat at 0%)	Flat 0%	Flat 0%	Flat 0%	Flat 0%	Flat 0%
Hands Off Protection	Off	Off	Off	Off	Off

The Steering Angle at 1080° matters because every ACC GT3 has a different real-world steering lock. McLaren 720S is 480°, Ferrari 296 is 800°, Porsche 992 is 800°, the Mercedes-AMG is somewhere different again. Lock your Pit House to 540° and you’re driving every car with the wrong ratio. Set it to 1080° and let ACC soft-lock to whatever the car wants – it just works.

In-game ACC settings

Setting	R5	R9	R12	R16	R21
Gain	95%	70%	60%	45%	35%
Min Force	0%	0%	0%	0%	0%
Dynamic Damping	60%	60%	60%	60%	60%
Road Effects	100%	100%	100%	100%	100%
FFB Frequency	400Hz	400Hz	400Hz	400Hz	400Hz

Dynamic Damping at 60%, not 100%. Kunos’s default is 100% on the assumption you’re running a lower-torque base where every bit of speed-scaling weight helps. On a Moza R12 or higher, you’ve already got plenty of inherent weight from the motor itself – stacking 100% Dynamic Damping on top makes the wheel feel like you’re stirring treacle through high-speed corners. 60% is the consensus that’s emerged. Drop further if you race long stints and want forearm relief.

Road Effects at 100% is non-negotiable on ACC. Coming from AC the temptation is to zero it out because in AC Road Effects is a canned sine-wave overlay that buries the actual physics signal. ACC’s Road Effects is the opposite – it’s real high-frequency suspension and tyre telemetry, and turning it off strips the page out of the book. You’ll feel the difference between a smooth section of Spa’s flat-out run and the slightly bumpier section through Eau Rouge with Road Effects at 100%. With it at 0% the track feels like glass.

The per-base sweet spot

One paragraph for each base because the temperament differs noticeably across the R-series.

The R5 at 95% Gain will clip on heavy GT3 corner loads. There’s no fix for that other than accepting the clip on the biggest corners (Eau Rouge, Pouhon, Copse) or stepping up to higher torque. The R5 is the genuine bargain entry to ACC – the FFB clarity at slow and medium loads is excellent. Heavy loads aren’t its strength and that’s fine.

R9 and R12 are where most Moza-on-ACC users land. The R12 specifically at 60% in-game Gain with the Wheel Damper at 25 is, honestly, the GT3 racing combo. Strong enough to feel real-world torque, light enough to race full stints without forearm pump. The R12 is the sweet spot.

R16 and R21 deliver real-world GT3 torque. Genuinely. The forces match what GT3 drivers report from real seats – which means by lap 30 of an endurance stint you’ll feel it. Drop Gain another 5% if forearms are protesting. The motor headroom is there, you don’t need to use it.

Common Moza + ACC mistakes

Road Effects at 0%. The AC carryover that ruins ACC. ACC’s Road Effects is real telemetry. Set to 100%.
Hands Off Protection ON. Occasionally cuts FFB mid-corner in ACC for unclear reasons. Turn off.
Steering Angle below 1080°. Every GT3 has its own real steering lock. Set Pit House to 1080, let ACC soft-lock per car.
Wheel Damper at 0 on the R12 or higher. Straight-line oscillation kicks in around 200 km/h. 20-25 in Pit House solves it without dulling cornering signal.
Gain at 100% on the R21. Severe clipping on heavy corners. 35% Gain on the R21, watch ACC’s in-game FFB telemetry widget go grey rather than red.
FFB EQ on anything other than Flat. ACC shapes its own signal. Re-shaping it through the EQ creates unpredictable cornering feel.
Dynamic Damping at 100% on the R12+. Treacle-through-corners feel. 60% is the sweet spot.

Get Wheel Damper right, get Road Effects right, and ACC on Moza is properly enjoyable for hours.
