I did not plan totest wheels for six years.

When the CSF2 went onto my S5 in 2019, I was thinking about fitment and feel. That was it. I wanted the car to look more planted, but I did not want a wheel that made the S5 feel cheap, nervous, or over-modified.

The S5 is a quick car, but it is not a tiny hatchback. It has quattro traction, real torque, a heavy front end, and enough speed to expose weak choices. A wheel that only looks good on installation day is not enough. It has to keep working after heat, rain, tyre changes, braking load, carpark ramps, and ordinary Singapore roads.

More than 90,000 km later, the CSF2 wheels are still on the car. That is why I can say more now than I could on day one. The first drive told me the car felt better. The years after that told me whether the choice was actually right.

Six years madethe answer obvious.

The S5 needed awheel with discipline.

The car still presentslike a proper build.

These photos were taken six years later, when I returned to LFI to swap out a worn centre cap. That matters to me. This was not a new-wheel handover or a fresh photoshoot. It was the same car, on the same CSF2 setup, after years of real use.

Sharper, calmer,more connected.

The S5 did not become a different car overnight. That is not what I wanted. What changed was the way the car responded when I started to drive it properly.

The front end felt cleaner. Turn-in had less delay. Over rougher surfaces, the suspension felt like it had less work to do. The car still had the weight and refinement of a fast GT, but it felt less reluctant when moving from braking to corner entry.

That is the part I appreciated more over time. One drive can impress you. Years of driving tell you whether the change still makes sense. The CSF2 setup kept the S5 feeling tied together without making it harsh or nervous.

Long-term strengthis quiet.

Performance wheel quality is not only about what you see on day one. It is about whether the wheel keeps doing its job after heat cycles, rain, washing, tyre changes, balancing, braking load, and ordinary road impacts that never make it into a social media caption.

After 90,000+ km, the thing I value most is that I do not think about the wheels every time I drive. They sit right, they clear the brakes, they stay composed, and they have continued to suit the car as the years passed.

Performance is morethan weight.

I cared about wheel weight, but I also learned that weight is not the whole story. A wheel can be light in the wrong places, stiff in the wrong places, or aggressive in a way that creates brake, tyre, or fender problems.

For a car like the Audi S5 B9, the wheel has to manage vehicle load, braking torque, lateral load, tyre support, and high-speed stability. The CSF2 worked because it was not just chosen from a catalogue. It was specified around the car.

The result is a wheel that felt good when it was new and still makes sense years later. That second part is the harder one.

The wheel still belongson the car.

After more than 90,000 km, the most convincing thing is not that the CSF2 still looks good. It is that the setup still feels appropriate.

The stance has aged well. The design still suits the body. The car still carries itself with the right balance of restraint and aggression. More importantly, the wheels have continued to support the way I drive the car.

That is what I wanted from a forged wheel. Not a temporary visual hit. Not one impressive number. A complete wheel specification that can stay with the car through years of real use.
