Choosing a performance exhaust system made from high-quality materials guarantees it withstands high-performance conditions. Each modification you make can bring you closer to achieving the aggressive tone and power you desire for your Audi S4.
Suspension Modifications

Suspension modifications can dramatically transform your Audi S4's handling and ride quality. Upgrading to 034Motorsport Dynamic+ Lowering Springs provides a 1.0-inch drop, enhancing your car's stance while improving overall handling. These springs work seamlessly with Audi's Adaptive Suspension, ensuring you maintain comfort without sacrificing performance.
For those who also appreciate aesthetics, consider pairing your suspension upgrades with unique planter designs to elevate your home decor alongside your vehicle's performance enhancements.
For a more personalized setup, consider installing adjustable coilovers. They allow you to fine-tune both height and dampening, greatly enhancing ride quality and handling characteristics.
Additionally, the 034Motorsport X-Brace, crafted from solid billet aluminum, boosts steering feel and reduces chassis flex, which is vital for maintaining ideal suspension geometry during spirited drives.
To further enhance drivetrain stability, you can also install a Rear Subframe Insert Package made from billet aluminum. This minimizes unwanted movement from factory rubber bushings, improving both drivetrain stability and suspension geometry.
Finally, incorporating a Billet Aluminum Drivetrain Insert Package reduces drivetrain movement, enhancing your shifting feel while preserving the OEM rubber dampening properties.
These combined modifications will create a more responsive and enjoyable driving experience in your Audi S4, making it a formidable contender on both the road and track.
Drivetrain Enhancements

To maximize your Audi S4's performance, consider upgrading the motor mounts and intake system.
These enhancements not only reduce engine movement for better power transfer but also boost horsepower and improve the engine sound.
Together, they create a more engaging driving experience, allowing you to fully enjoy your tuned ride.
Motor Mount Upgrades
When you're looking to enhance your Audi S4's performance, motor mount upgrades can make a notable difference. Upgrading to performance motor mounts reduces engine movement, leading to improved power transfer and more precise handling during acceleration.
These aftermarket motor mounts are typically crafted from stiffer materials, providing enhanced feedback and responsiveness in the drivetrain compared to stock components.
With upgraded motor mounts, you'll notice a remarkable improvement in traction as they minimize wheel hop during hard launches. This reduction in unwanted movement is fundamental for maximizing overall vehicle performance, especially if you've made other tuning upgrades like ECU tuning or supercharger installations.
It's imperative to verify compatibility with your specific Audi S4 model when selecting motor mounts. Options like 034Motorsport's performance mounts can greatly enhance your driving experience.
By investing in these upgrades, you'll not only enjoy better handling but also a more connected feel between you and your vehicle.
