Tires and Wheels
The McLaren GT’s 225/35R20 front and 295/30R21 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the AMG SL’s standard 40 series front and 35 series rear tires.
For better ride, handling and brake cooling the McLaren GT has standard 21-inch rear wheels. Smaller 20-inch wheels are standard on the AMG SL.
Suspension and Handling
The McLaren GT has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The AMG SL doesn’t offer a load leveling suspension.
For better handling and stability, the track (width between the wheels) on the McLaren GT is .3 inches wider in the front and 1.5 inches wider in the rear than the average track on the AMG SL.
For better maneuverability, the McLaren GT’s turning circle is 1.1 feet tighter than the AMG SL’s (39.6 feet vs. 40.7 feet).
