Dodge Challenger SRT Demon

The meta Dodge Challenger SRT Demon build for Forza Horizon 6, tuned to the current Rivals leaderboards.

The Dodge Challenger SRT Demon is a Forza Horizon 6 meta pick for Drag at S2 class. Run it RWD with Stock or 8.9L V8 DSC options. This page has the full meta build: the upgrade order, the exact tuning values and why it works.

Why it is meta

Drag (S2, RWD, Stock or 8.9L V8 DSC options): Built for the strip: long body for weight transfer and huge rear tyre width available.

Drag racing is pure straight-line speed. Every upgrade should focus on maximising power and traction off the line. Weight reduction is critical. The car needs to launch hard without spinning the wheels, then accelerate as fast as possible to the finish.

Upgrade priority

  1. Biggest Engine Swap Available Drag is pure power. The largest engine you can fit gives the most horsepower per PI spent. V12s, twin-turbo V8s, and supercharged options are all strong.
  2. Max Power Upgrades Stack turbo, intercooler, exhaust, intake, cam, valves, and displacement on top of the engine swap. Every horsepower matters in a straight line.
  3. Consider AWD Swap AWD launches harder than RWD because all four wheels put power down. The PI cost is significant but the launch advantage usually outweighs it at most classes.

Tuning

Tyres

SettingValue
CompoundDrag
Front Tyre WidthStock or narrowest
Rear Tyre WidthMaximum
Front Pressure30.0 to 32.0 PSI
Rear Pressure18.0 to 20.0 PSI

Narrow front tyres and high front pressure reduce rolling resistance. Max rear width for launch traction. Very low rear pressure grows the contact patch and grabs harder off the line. Drop rear pressure 1 PSI at a time; too low and the tyre gets vague, too high and you spin.

Gearing

SettingValue
Final Drive (1/4 mile)3.76 (assumes ~1050 hp)
Final Drive (1/2 mile+)3.22
6-Speed Ratios2.97 / 2.07 / 1.6 / 1.3 / 1.1 / 0.96
StrategyEach gear should hit the rev limiter just as you shift

Quarter-mile runs want the shorter final drive; half-mile and roll racing want the longer one. Set top gear so you just reach trap speed at the finish, then bring the lower gears up into a smooth curve. Tune 1st gear iteratively on the strip: it should launch hard with controllable wheelspin. With 8 to 10 gears, keep the same 1st and top ratios and space the rest evenly.

Alignment

SettingValue
All Camber0.0
All Toe0.0
Caster5.0

Zero everything for maximum straight-line contact patch and minimal rolling resistance.

Anti-Roll Bars

SettingValue
FrontMinimum
RearMinimum

Minimum ARBs allow maximum weight transfer to the rear on launch.

Springs

SettingValue
Front Springs375 lbs/in (soft)
Rear Springs750 lbs/in (stiff)
Front Ride HeightMinimum
Rear Ride HeightOne or two notches above minimum

Stiff rear springs support weight transfer on launch. The front is halved to let weight shift rearward. Minimum front height reduces drag and front lift at speed, while a slightly raised rear gives the suspension room to squat on launch and plant the tyres.

Damping

SettingValue
Front Rebound4.0 to 5.0
Rear Rebound8.0 to 10.0
Front Bump2.5 to 3.0
Rear Bump5.0 to 6.0

Stiff rear damping resists squat and keeps the rear planted under hard acceleration. Soft front allows weight to transfer rearward on launch. Bump is roughly 60% of rebound.

Aero

SettingValue
Front DownforceRemove front aero if possible
Rear DownforceMinimum or remove (add rear wing only if wheelspin is severe)

Less downforce means less aerodynamic drag and higher top speed. Only add a rear wing if you cannot control wheelspin through gearing and differential alone. Front aero adds drag with no benefit in a straight line.

Brakes

SettingValue
Brake Balance50%
Brake Pressure100%

Brakes are rarely used in drag racing, but balanced pressure helps if you need to stop at the end of a strip.

Differential

SettingValue
Acceleration100%
Deceleration0%

Full lock on acceleration ensures both driven wheels put power down equally.
