The Audi A4 has been the cash cow for the brand with the four rings for 50 years. As a sedan, Avant, and in the sporty variants S4 and RS4, the Audi A4 inspires a particularly broad target group. If you are looking for a particularly performance coilover suspension for the Audi A4 B9, you will find it here!

When the Audi 80 established today’s A4 series in 1972, 110 hp was the highest output. Over the decades, the power quadrupled! Today, the leading model in the A4 portfolio is the Audi RS4 with 450 hp. The most successful representative of the mid-size series is the Audi A4 Avant. THE station wagon of all.

Audi A4 Avant: THE station wagon

The Audi A4 B9, presented in 2015, is based on the enhanced modular Volkswagen platform “MLB Evo”. In 2019, Audi gave the A4 a surprisingly extensive facelift. With a new, more elegant look, a new interior and new engines, the A4 entered the second half of its life.

If you are looking for a stylishly designed station wagon or a sedan with a clear and concise design, the Audi A4 Avant is the perfect choice. And with the Audi S4 and RS4, the Ingolstadt-based company also has exciting options in its lineup for drivers with a sporty bent.

Audi RS4: The 450 hp powerhouse

The track day organizer and BILSTEIN partner all4track, for example, relies on the Audi RS4. “When we were looking for new company vehicles, we quickly came across the Audi RS4,” explains Kilian Weitz, one of two managing directors at all4track AG from Germany. “It is always important for us to have a certain multipurpose functionality. We have to transport a lot for our events. In addition, I regularly drive to the office with my two dogs. Of course, we could also drive an Audi A4 TDI. But if you want to promote lifestyle and fun driving as a company, there’s not much left in the station wagon segment.”

And because the all4track RS4 often has to operate as an upfront vehicle for guided driving on the race track, the company opted for a high-performance coilover suspension system from BILSTEIN.

The BILSTEIN EVO T1 coilover suspension kit for the Audi RS4

The brand-new BILSTEIN EVO T1 coilover suspension is now at work in the strikingly foiled 450-hp estate from all4track. Visually alone, the suspension really makes a statement. In sophisticated matte black and with its blue color highlights, the coilover suspension looks just too good even before it’s installed. Once installed, sporty drivers for whom appealing looks and superior driving dynamics are important will be in their element.

Because the “T” stands for “track”, sporty drivers can expect a sports suspension with spectacular handling that also makes an excellent impression on the racetrack. And that’s exactly where the BILSTEIN EVO T1 impresses with its sporty, precise steering feel and even more direct contact with the road.

A travel station wagon becomes a track monster

This is also confirmed by track day pro Kilian, for whom a certain level of racetrack compatibility is very important. “With the BILSTEIN coilover suspension, the RS4 drives extremely directly. What’s more, the car now has much less side roll, especially in fast corners.

Kilian is particularly impressed by the ease of handling. After all, he drives the Audi RS4 not only on the track, but also on the road. “The suspension is extremely easy to adjust in rebound and compression damping via 10 clicks. And that’s in the installed state! When it’s time to go to the track, I set the coilover suspension two clicks harder and immediately have a firmer setup. Then the RS4 is a completely different car,” says the Audi driver enthusiastically. When Kilian returns home from the race track, the fast Audi quickly becomes a daily driver again.

Spectacular lowering

“For my everyday car, the look is everything,” reveals Kilian. “And the roof box is always part of the package for me, too, because it offers plenty of space and looks stylish.” Maximum style is also made possible by the BILSTEIN EVO T1. “The RS4 with the coilover suspension sits significantly lower on the road. And is a real eye-catcher visually. The car is simply awesome, a really cool daily.” We can’t – and won’t – disagree with that at this point.
