Brake heat builds up faster than most people expect.

You push the car, get into a few hard stops, and suddenly temperatures are climbing. At the same time, air is getting trapped in the wheel wells.

That combination affects both cooling and aerodynamics.

Front fender louvers fix both.

They give hot air a way out of the wheel wells, which helps reduce temperature buildup and keeps airflow moving properly along the sides of the car.

Less pressure, better cooling, and cleaner aero.

You end up with a car that performs more consistently, especially if you’re driving aggressively or doing track sessions.

This isn’t just about looks, even though they do look like they belong on a proper track build.

This is about solving a real problem.

We build them in carbon fibre to keep weight down and durability up, and they’re designed to fit properly without compromising the car’s structure or airflow.

If you actually use your GT4 RS the way it was meant to be used, this upgrade just makes sense.

It’s functional, it’s clean, and it works.
