Audi RS3 (8Y) Tuning & Performance Parts

The Audi RS3 8Y is the most aggressive five-cylinder RS3 yet - 400PS from the legendary 2.5 TFSI, torque-vectoring RS Torque Splitter and a chassis sharpened to match.

At Awesome, we've spent years unlocking the platform's hidden potential, from software calibrations that take you well beyond factory figures to suspension, intake, exhaust and brake upgrades built for fast road and track use.

Whether you're chasing lap times at Bedford or a cleaner, louder daily drive, you'll find everything you need to transform your 8Y into the car Audi hinted at. Shop by category below to build your RS3.
