Fiat 500 Abarth USA Model & Dodge Dart 1.4 Multiair Uprated Billet Camshaft – TMC Motorsport Speciale

The TMC Motorsport Speciale Uprated Billet Camshaft is engineered to extract serious performance gains from your 1.4 Multiair engine—developed specifically for the Fiat 500 Abarth (USA Model) and Dodge Dart. Whether you're building a powerful road setup or chasing podiums on track, this upgrade delivers enhanced lift, optimised timing, and improved airflow—unlocking sharper throttle response and increased high-end power.

Manufactured exclusively for TMC Motorsport by Piper Cams, this camshaft benefits from over 60 years of motorsport camshaft expertise. With a legacy that spans Formula 1, Le Mans, WRC, WTCC, NASCAR, and IndyCar, Piper’s precision engineering brings championship-grade performance to your Multiair-powered build.

Each camshaft is CNC-machined from premium billet EN40B steel, ensuring maximum strength and consistency under stress. To further increase durability and reduce friction, Piper applies an in-house advanced finishing process—specifically designed to complement DLC-coated valve train components. This not only boosts performance by lowering heat build-up but also extends component lifespan under aggressive conditions.
