Aston Martin DB11 Tuning Guide — Best S1 Setup

Class Range: A800 - S1 900 | Base Horsepower: 630 hp | Drivetrain: RWD | Weight: 1770 kg | Best Class: S1 900

The DB11 is an underrated GT in FH6. Most people see the 1770 kg curb weight and RWD layout and immediately write it off as heavy and hard to drive. Honestly, I thought the same at first — until a DB11 caught up to me from behind on the highway one day, and I realized just how fast this car is once it's tuned right.

The twin-turbo V12's power delivery is genuinely pleasant — not the violent, tire-smoking kind, but a constant, unrelenting shove you can feel from 2000 rpm. That linear torque makes throttle control easy through fast corners, unlike some turbo cars that force you to feather the pedal.

The car's core problem is that the stock suspension is too soft — classic GT tuning. It's comfortable, sure, but the moment you hit a sequence of corners it falls apart, with body roll so heavy it feels like the car might tip over. That's exactly what tuning can fix, so here are the numbers.

Best Tuning Setup for S1 900

The Road GT build chases high-speed cruising ability, stretching top speed on tracks with long straights. The Sport build drops a bit of horsepower but sharpens the handling, which suits technical circuits. Bottom line: pick based on the map — Road GT for highways, Sport for mountain courses.

Tuning Parameters — Every Setting Explained

Tire Pressure

Front 2.1 bar / Rear 2.0 bar. The DB11 is nose-heavy, so the front tires heat up faster and a slightly higher pressure helps shed heat. Once warmed up, pressures float between 2.3–2.4, right in the sweet spot for semi-slicks.

Transmission

Final drive ratio 3.73. This car has 7 forward gears, and the stock ratios are on the tall side — great for cruising and fuel economy, but wasted time on a racetrack. Tighten gears 2–5, and stretch 6–7 out as cruising gears. The V12's low-end torque is so strong that even with close ratios, it never feels like you're shifting constantly.

Alignment

Front Toe 0.0 / Rear Toe +0.1, Front Camber -1.5 / Rear Camber -1.2, Caster 6.2 degrees. The DB11's rear axle slides slightly sideways in fast corners, so a touch of positive rear toe keeps the tail calmer. Don't go too aggressive on front camber — it already understeers, and -1.5 degrees balances straight-line stability with cornering grip.

Anti-Roll Bars

Front 30.5 / Rear 26.0. Stiff front, soft rear — the classic anti-understeer setup. Unlike the NSX, this car can't rotate via torque vectoring — it's pure RWD, so the anti-roll bars are the only balance tool you have. A stiffer front bar cleans up turn-in nicely.

Springs

Front 580 / Rear 520 (lbs/in). Both are about 30% stiffer than stock, but the rear axle stays a bit softer to protect traction. On a high-power RWD car, whether the rear tires bite on corner exit comes down entirely to getting the springs right.

Damping

Rebound Front 9.5 / Rear 8.0, Bump Front 6.0 / Rear 5.0. This setup trades a little comfort over small bumps for a big jump in body control. Body roll through fast corners drops by at least 40%.

Aero

The DB11's stock aero is weak, so I'd add a front lip and rear diffuser. Set the wing angle to medium — don't chase maximum downforce. The DB11 is a GT after all; top speed is its real weapon.

Brakes

Brake balance front-biased at 48%, pressure 120%. At 1770 kg the car is no featherweight, so give the brakes plenty. The front bias is because weight shifts forward under hard braking, and the front wheels carry more load so they're less likely to lock up.

Differential

Accel lock 65% / Decel lock 30%. High accel lock makes both rear wheels drive together — exactly what a high-power RWD car wants. Low decel lock lets the tail follow freely into corners instead of locking up and pushing the nose wide.

Driving Tips

The essence of driving the DB11 comes down to two words: smooth throttle. The V12's torque is so massive that flooring it in second gear out of a corner basically means doing donuts in place. Learn to take low- and mid-speed corners in third or even fourth gear, letting torque push you out instead of revs. Fast corners are its home turf — hold the throttle at 4500 rpm in fourth and the car feels as planted as a bullet train. One more thing: be careful in the rain. The rear tires are wide but the weight is there, and wet grip drops off noticeably — get on the throttle half a beat later than you would in the dry. Oh, and the sound is genuinely gorgeous; a V12 howling at 7000 rpm is worth the price of admission on its own.
