Porsche - The chassis

The chassis 911 GT3 Cup

In the race department at Weissach, the suspension underwent modifications to ensure higher precision and more stability at high speeds. Compared to its predecessor, the wheelbase grew by 100 millimetres, improving handling at the limit. Porsche Motorsport redesigned the single-piece 18 inch race rims with central locking. The width of the Michelin racing slicks at the front axle grew by two centimetres to now measure 27 cm, and at the rear axle by one cm to 31 cm.
