McLaren 570s 600 LT Sidewall Right Left

McLaren parts catalog for 2026, the term “Sidewall” (or Side Panel) typically refers to the large structural and aesthetic body panel that runs along the side of the car, incorporating the Rocker Panel and the Rear Quarter Panel area.

For the 600LT, this is a critical aero component because it incorporates the extended side intakes and the mounting points for the “Longtail” side blades.

2. 600LT vs. 570S Differences

It is important to note that while the 570S and 600LT share the same chassis, the sidewalls are not identical:

• The 600LT Sidewall is sculpted differently to accommodate the larger, more aggressive air intakes.

• Mounting Points: The 600LT sidewall has reinforced mounting points for the extended carbon fiber side skirts.

• Airflow: The internal ducting within the 600LT sidewall is optimized for higher cooling demands.
