Nitrous in ProStreet needs to be tuned for immediate power delivery rather than long-lasting speed.

Set your rear spring rates and shock absorbers (bound/rebound) to be soft (left side of the slider). This allows the weight to transfer to the back wheels, boosting traction.

Your tuning work fails without driver execution.

Set to Stiff . This prevents the rear of the car from squatting too deeply, which can cause unstable bouncing and loss of traction. Ride Height Front Ride Height: Set to Low . Rear Ride Height: Set to High .

Drag tuning in this game is about balancing three warring factors:

This creates a raked stance. It keeps air from getting under the car, increasing stability and preventing dangerous, time-wasting wheelies on powerful rear-wheel-drive (RWD) cars. Toe and Camber Camber (Front & Rear): Set to 0 (Neutral) . Toe (Front & Rear): Set to 0 (Neutral) .

Aerodynamics play a massive role in the 1/2-mile events where cars exceed 200 MPH.

Set nitrous flow to a high rate, but ensure it lasts through the gears where you need it most (typically 4th gear and above). :

| Setting | Recommendation | Explanation | |---------|----------------|-------------| | | Start at 4.10 – 4.30. Adjust so you just hit redline at the finish line in top gear. | Too tall (low number) = slow acceleration. Too short (high number) = run out of gear early. | | 1st Gear | Lengthen by 15-20% (move slider toward “Speed”) | Prevents instant wheelspin. A longer 1st gear lets the car build momentum before torque spikes. | | 2nd Gear | Slightly shorter than default | Bridges the gap between 1st and 3rd smoothly. | | 3rd–Top Gear | Standard to slightly shorter | Keep engine in peak power band (usually 80-100% of redline). | | Limited Slip (LSD) | 100% acceleration sensitivity / 0% deceleration | Full lock on acceleration = both rear tires spin together. Decel lock doesn’t matter in drag. |

Always install Stage 4 parts to maximize potential, then update your blueprint. 2. Gearbox Tuning (Gearing)
