The 3RACING F109-03/FRP Main Chassis and Upper Deck is engineered to reduce unwanted chassis flex and give tuners a firmer baseline. Its FRP construction is suited to drivers focusing on handling precision and consistent lap times.
FRP provides a predictable stiffness characteristic that helps maintain suspension geometry through dynamic loads. Tuners can exploit the reduced compliance to dial in finer spring and damper settings for improved cornering stability.
Designed for track environments, this upgrade supports aggressive setups and frequent adjustments, enabling straightforward changes to balance and weight distribution without compromising durability.
