How to tune the carparkingGTR for maximum speed?

You can adjust the intake and exhaust spark plug cylinder wires to improve the corresponding power. Adjust the ECU grounding wire. Use the throttle with oil pressure control valve and tune the exhaust to make the intake smoother, etc.

When tuning the track-spec GTR, I prioritize overall balance. For the chassis, I stiffen the front anti-roll bar by two clicks and lower the rear suspension by 15mm for sharper cornering. The optimal launch control RPM for the transmission is between 2,800-3,200 to minimize clutch wear. Don't just chase peak horsepower - mid-range torque is more important, and maintaining stable turbo pressure around 1.5bar is crucial. Downforce tuning depends on the specific track: increase rear wing angle for circuits with many high-speed corners, though this costs about 5% top speed on straights. A cold tire pressure of 26psi provides the best balance, naturally rising to 32psi when hot to stay within the optimal operating window. These parameters are the ideal combination I've developed through countless Nürburgring lap attempts.

My experience driving the GTR at Tsukuba Circuit taught me that the steering assist must be set to the heaviest mode. Although it's more strenuous during parking, it provides a clear sense of front-wheel grip at high speeds. The brake balance should be set to 70% front and 30% rear, with the ABS intervention level reduced by one step to prevent premature cut-off of braking force. After increasing the preload of the active differential by 30%, the car's rear end becomes more responsive when accelerating out of corners. The cooling system is often overlooked—I always install an additional transmission oil cooler, otherwise the oil temperature exceeds 120°C after just three laps. The most practical tip is to turn off the auto-rev matching function and use heel-toe technique for more precise control. Fine-tuning these details is far more useful than simply adding horsepower.

Tuning the GTR requires targeted adjustments. If you experience understeer in corners, first adjust the front toe angle to 0.5 degrees toe-out; for oversteer, widen the rear wheels by 20mm. For daily driving, PS4S tires are sufficient, but for track days, switch to Trofeo R and remember to warm them up to 90 degrees before timing laps. For power modifications, prioritize ECU tuning to remove factory speed limits, then install a high-flow catalytic converter to avoid check engine lights. Choose Endless MX72 brake pads, as the factory discs can withstand 30 minutes of aggressive driving. Most crucially, install a set of lightweight wheels—saving 1kg of unsprung weight is equivalent to reducing 10kg of vehicle weight.
