Audi racing parts are engineered to deliver precise control, lighter weight, and an unmistakable edge on both the street and the track.
As passionate enthusiasts, we know you want solutions that not only look the part but also provide real aerodynamic and performance gains.
In this article, we break down eight essential upgrades—each selected for its ability to sharpen handling, improve airflow, and create a cohesive, OEM-plus Audi build.
1. Carbon Fiber Front Splitter for Audi S and RS Models
If you’re serious about grip and stability at every corner, this is where you start. A carbon fiber front splitter takes your Audi S or RS from flow to function, dialing in actual aerodynamic gains—not just looks.
Here’s what separates a game-changer splitter from an off-the-shelf add-on:
- Dry pre-preg carbon fiber construction delivers high strength with less weight. The material is heat- and UV-resistant, so you get durability and that gloss, OEM-plus finish Audi owners crave.
- Wind-tunnel developed aero on the right splitter can double your front downforce at highway speeds. That’s not a claim, that’s a real-world lap advantage and a sharper steering feel in every corner.
- True fitment means every contour hugs your Audi’s bumper and undertray. For RS3 8Y, S4/RS4 B9, S5/RS5 B9, TT RS, and R8 owners, this matters for both performance and aesthetics.
- Rigid mounting hardware and even gasket compression stop high-speed flutter and prevent misalignment, even with adaptive cruise sensors.
- Carbon fiber care: add film protection on leading edges and inspect hardware after track days for peace of mind.
We obsess over the engineering. At ASM Tuning, our carbon aero is model-specific, made with dry pre-preg carbon, and finished for UV stability and a flawless gloss. Our approach favors structure and style—see the difference in our full body kits and performance guides.
Aerodynamic gains only matter when the airflow is managed and the fitment is flawless.
2. Carbon Fiber Rear Diffuser for Stability and Exhaust Flow Management
Rear-end confidence changes everything. A high-quality carbon diffuser gives your RS or S Audi purpose on fast sweepers, controls underbody airflow, and keeps things stable deep into braking zones.
A few priorities make all the difference:
- Integrated strakes and gradual angle transitions control flow, kill turbulence, and manage rear-end lift. You’ll notice stability in fast corners even at stock ride height.
- Dry pre-preg carbon fiber stands up to exhaust heat and drops tail weight, which sharpens transient chassis response. ABS is heavier and gets stressed near hot rear tips.
- Direct-fit for RS3, S/RS4/5, TT RS, or R8 models delivers stability where it’s needed while ensuring clean integration with the existing undertray.
- Proper installation means bumper tab seating, OE clip reuse where possible, and no exhaust tip clearance issues—even if you’re running an aftermarket cat-back.
Our carbon aero program at ASM Tuning focuses on clean undertray transitions, robust reinforcements, and UV-stable clear coats. You’ll find the difference in both the fit and the finish—not to mention confident rear stability at speed.
Every diffuser install should end with a check for gaps—no leaks, no lost airflow benefits.
3. Carbon Fiber Trunk Spoiler or Swan-Neck Wing for Tuned Downforce
If you want balance, not just style, this is the next step. Pick your part based on driving focus—then see how quickly you unlock real, measurable downforce for your Audi.
Which Downforce Device Fits You?
- Lip spoiler: Adds subtle, street-ready downforce that blends with OE lines. Perfect for daily-driven RS3, S4 or S5 builds where you crave grip and want that understated look.
- Swan-neck wing: Maximum rear grip, especially on track. Clean airflow and real downforce without disrupting the car’s silhouette. Ideal for RS, TT RS, or R8 track day owners hunting for lap-time consistency.
Fitment Matters
- You get tight matches to trunk curvature, adhesive solutions that are paint-safe, and full compatibility with trunk sensors or actuation.
- With big wings, reinforced base plates and metal cores stop flutter, crush, or stress cracking—critical for track and endurance use.
- OEM integration means you don’t lose daily function, parking sensors, or access.
We don’t just produce spoilers or wings that look the part. Our ASM Design carbon pieces emphasize finish quality, mounting integrity, and real aerodynamic gains. Discover our philosophy by checking out our latest carbon styling and finish resources.
Downforce is only an advantage when it’s balanced, integrated, and fit to your car’s daily and track realities.
4. Valved Stainless Cat-Back Exhaust for Power, Tone, and Control
Exhaust matters. Lighter, freer, and sharper—without drone or highway fatigue. A quality valved cat-back transforms your Audi’s responsiveness, torque, and driving feel.
Valved Cat-Back Key Advantages
- T304 stainless resists corrosion and delivers long-term durability, even after countless heat cycles. Mandrel-bent pipes and straight-through mufflers kill backpressure while keeping things civil on the highway.
- Valved systems let you shift from stealth to aggressive in seconds. True integration means seamless OEM drive mode control—no awkward error messages or wiring hacks.
- Expect single or low double-digit horsepower boosts, especially when added to a downpipe and tune, with sharper throttle and more mid-range punch.
- Install highlights: tip length should protect the bumper, tip spacing must work with diffusers, and hanger alignment avoids costly rattles.
- Warranty matters. We back our ASM valved stainless exhausts with robust coverage detailed in our warranty guide, so you know your investment is protected.
For the best results, make sure your exhaust supports the full system: proper mounting, tight tolerances, and integration with existing sensors means long-term satisfaction.
5. High-Flow Sport Downpipes for Turbocharged Audis
Ready to break the bottleneck? The downpipe is the first and biggest restriction in your exhaust after the turbo. Upgrade it, and every boost hit feels sharper and more urgent.
- A high-flow 200-cell catted or de-cat downpipe instantly reduces backpressure, speeds up turbo spool, and unlocks serious power gains—especially when tuned.
- Built from 304L stainless with precise CNC flanges and smooth transitions, these resist heat and stress while providing a perfect seal for years of abuse.
- You’ll see quicker 60–130 times and more consistent power throughout spirited driving sessions—especially if heat soak and inconsistency held you back.
- Sport cats offer a real compromise: they keep emissions under control while delivering most of the flow gain. De-cat pipes deliver maximum gains, but always check local rules.
- Every install should feature heat shields near the firewall, perfect fit to subframe, and guaranteed O2 sensor health with every connection.
At ASM Tuning, downpipe geometry and wall thickness aren’t just specs—they determine turbine health and real-world performance. Our focus is on proven gains, precise fit, and unbeatable weld quality that delivers reliable results on the street and the track.
6. Forged Monoblock Wheels for Unsprung Mass and Brake Clearance
Your wheels do more than set the look. Go forged, and you transform how your Audi handles, accelerates, and puts down power. This isn’t just for show—it’s a physics upgrade you feel every drive.
Why Forged Wheels Change the Game
- 6061-T6 monoblock construction means less weight where it matters. That sharper turn-in, the easier straight-line launches—you feel it within the first block.
- Proper fitment clears the biggest S/RS brakes, including ceramics. That means no guesswork or grinding, just simple, precise installation.
- Every wheel passes FEA validation to confirm it won’t flex or fatigue—so you get max durability alongside the weight savings.
- Hub-centric bores, knurled beads, and optimized pockets? Those features keep tires in place and maintain consistent grip, lap after lap.
Our ASM Forged Wheels program lets you spec to your exact stance, brake, and finish targets. We support you with fitting advice, color choices, and guaranteed hub, barrel, and cap alignment—no more mismatched or rubbing setups.
Lighter wheels free up your suspension and unleash real, measurable response. It’s instant reward for every driver.
7. Big Brake Kit With Track Pads, Lines, and Fluid
If you want to stop as hard as you go, brakes are non-negotiable. A proper big brake kit doesn’t just look tough. It raises your thermal threshold, sharpens pedal feel, and gives you repeatable, fade-free stopping.
What You Need for Real Stopping Power
- Multi-piston calipers deliver firm, progressive bite without flex. Two-piece rotors run cooler and resist warping under abuse. Stainless steel lines bring pedal confidence.
- Race pads? Sure, but don’t skip fluid. DOT 4 or higher with a high dry boil point keeps you protected in heavy traffic or the longest track session.
- It’s about the whole system: bias must suit your car and tire, and ABS integration prevents surprises under panic stops.
- Forged wheels often unlock extra caliper clearance, so kit and wheel play together for true brake and fitment synergy.
We always recommend proper bed-in and a post-track check. Check pad taper. Look for glazing. These simple steps extend rotor and pad life and keep every lap predictable.
8. High-Efficiency Intercooler Upgrade for Turbo Audi Engines
Tuned Audis heat up. If you want to run full power without timing pull and consistency loss, you need to address your intake temps head-on. An upgraded intercooler is the linchpin.
What Sets an Elite Intercooler Apart
- Bar-and-plate cores store more heat and resist soak on back-to-back runs. That means more stable intake air temps and sustained boost, even on hot track days.
- Well-designed end tanks avoid pressure drops and distribute air evenly, feeding every cylinder the same cool, dense charge. Uniform fueling, safer power.
- Fitment is critical: oversized cores won’t choke off airflow to the radiator. Well-placed shrouding and reliable couplers complete the install.
- Upgraded charge pipes and clamps seal the system, keeping boost where it belongs.
We treat airflow as a system. Pairing intercoolers with downpipes and exhaust brings net gains that matter on the road and in the data. Lean on our fitment guides and install expertise to keep your build leak-free and heat-resistant.
