Best Audi R8 4S Upgrades: Nose Lift, Coilovers & Brakes

The best Audi R8 4S upgrades start with the one thing Audi never offered: a front nose lift. The second-generation R8 (Type 4S, US model years 2017–2023) shares its 5.2 FSI V10 and aluminum-and-carbon spaceframe with the Lamborghini Huracán — but where the Huracán could be ordered with a factory front axle lift, the R8 never could, in any year or trim. That single omission is why R8 owners grind splitters on driveways they clear in every other car they own. This guide ranks the suspension, brake, fuel, and sound upgrades that actually matter on a 4S, with real part numbers, real fitment, and the two compatibility traps — magnetic ride and carbon-ceramic brakes — that decide whether a part fits your car at all.

Why Does My Audi R8 Scrape on Driveways?

An Audi R8 scrapes because of its long front overhang and low front splitter, not because it sits especially low. Ground clearance on a stock 4S is commonly quoted at roughly 4.1–4.3 in, which is not unusual for a mid-engine car — but the R8 carries a lot of bodywork ahead of its front wheels. On a steep driveway transition or a Tampa speed bump, the leading edge of the splitter and the plastic brake ducts contact the pavement long before the floor does. It is an approach-angle problem, and no amount of tire pressure or careful angling fixes it.

Audi's answer was to not have one. There is no factory front lift on the Audi R8 4S in any US model year — a fact worth confirming before you shop, because the R8's platform twin, the Lamborghini Huracán, does offer a factory front axle lift, and plenty of forum advice conflates the two. The result: the aftermarket nose lift is not a vanity mod on this car. It is the fix for a design gap.

Best Audi R8 Nose Lift: KW HLS With V4

The KW Hydraulic Lift System (HLS) raises the R8's front axle by up to roughly 45 mm — about 1.8 in — in 4 to 5 seconds, and it can be raised while driving at speeds up to about 50 mph (80 km/h). Rather than an air bladder, KW integrates a hydraulic ram into the coilover body between the spring perch and the spring. Pressurizing the ram extends the perch and lifts the nose; because the extended cylinder is rigid, it does not eat into suspension travel or soften the damping while you drive on it. A vehicle-specific pump and reservoir, an electronic control module, and an in-cabin LED control button complete the kit, and KW supplies it with a technical component (TÜV) report.

HLS 2 vs HLS 4: Which Do You Need?

HLS 2 lifts the front axle only; HLS 4 lifts front and rear. For an R8, HLS 2 is the correct choice for nearly every owner, because the R8 does not scrape at the back — the whole problem is the approach angle at the nose. HLS 4 exists for cars that need to clear an obstacle with the entire chassis while holding factory rake, which is rarely the R8's situation. The kit NLP stocks is the HLS 2 front-axle system bundled with KW's V4 coilovers.

What Makes KW V4 Different From V3?

KW V4 is a three-way adjustable coilover: it separates low-speed compression, high-speed compression, and rebound into three independent adjusters. KW's V3, by comparison, is two-way — 12 clicks of compression and 16 clicks of rebound. The V4 keeps the 16-click rebound adjuster and adds a remote-reservoir compression circuit (KW calls the technology TVCLH-A) with 6 clicks of low-speed compression and 15 clicks of high-speed compression.

In practice, those knobs do different jobs. Low-speed compression governs body roll on turn-in and pitch under braking and throttle — the slow, deliberate weight transfer you feel on a back road. High-speed compression governs sharp, fast inputs: expansion joints, potholes, curbing. Rebound controls how quickly the wheel extends again, which is what makes a car feel settled rather than floaty. On a 600-plus-horsepower mid-engine car that gets driven on real Florida roads and the occasional track day, being able to soften high-speed compression for pavement quality without giving up low-speed body control is the entire argument for V4 over V3.

Can You Lower an Audi R8 and Keep Magnetic Ride?

Yes — but only with an adjustable spring kit, not with coilovers. This is the most misunderstood spec in R8 suspension, and it is worth stating bluntly: a coilover kit labeled "with Adaptive Suspension" does not retain your adaptive suspension. It means the opposite. That version is the one built for cars that left the factory with magnetic ride, and it ships with an electronic damping module (EBM) cancellation kit whose job is to replace the magnetic dampers entirely and suppress the dash fault light that would otherwise appear.

Magnetic ride was an option on the R8 4S, not standard equipment, so step one is knowing which car you have. If you have it and want to keep it, your path is an adjustable lowering spring that works with the factory dampers. If you are willing to give it up in exchange for real damping control, the coilovers below are the upgrade.

H&R VTF Adjustable Lowering Springs — Keeps Your Factory Dampers

VTF stands for Verstellbare Tieferlegungsfedern — German for adjustable lowering springs. The kit uses a threaded lower perch so you can dial in ride height precisely instead of accepting whatever drop a fixed spring gives you, and critically, it is engineered around the factory dampers. On a magnetic-ride R8 that means Audi Drive Select damper modes keep working, there is no cancellation module, and there is no damper warning light. At $1,152 with roughly 0.25 in to 1.2 in of adjustment, it is the right answer for the large majority of R8 owners who want a modest stance drop and want to keep the car behaving like an R8.

KW Height Adjustable Spring Kit — The Middle Path

KW's H.A.S. kit is the same idea from the other major German suspension house: height-adjustable springs that bolt to your existing dampers, so you get infinitely adjustable ride height without replacing the shock. At $1,864 it sits between the H&R VTF springs and a full coilover. Because it is a spring-only kit it retains the factory damper hardware; if your car has magnetic ride, confirm the specific application before ordering, since compatibility with the adaptive strut varies by kit.

Audi R8 4S Coilovers: H&R RSS+ Coil-Over

The H&R RSS+ is a monotube coilover with lightweight aluminum threaded shock bodies and a single external damping adjuster that tunes rebound and compression together. That is the honest distinction from the KW V4: RSS+ gives you one knob, V4 gives you three independent circuits. For a street car that sees the occasional canyon or track day, one well-chosen setting is often enough — and the RSS+ costs roughly a quarter of the KW HLS package.

On the R8 4S, H&R publishes a lowering range of roughly 0.6–1.4 in at the front and 0.8–1.6 in at the rear. Be careful with retailer listings here: several sites reprint H&R's generic RSS+ boilerplate claiming a 1.5–2.7 in drop, which is not the R8-specific figure. NLP stocks both versions — part number 32132-2 for cars with adaptive suspension ($4,005.00), which includes the EBM cancellation kit, and part number 32132-1 for cars without it ($4,572.00). Picking between those two part numbers is the step we spend the most time on with R8 customers, and it is the one that goes wrong most often when people order elsewhere: get it backwards and you end up with either a permanent fault light on the dash or a set of struts that will not mount to your car.

Audi R8 4S Suspension Compared

Best Audi R8 Brake Upgrades (Read This First)

Before you buy a single brake part for an R8 4S, find out whether your car has steel rotors or carbon-ceramic brakes (CCB), because a steel-brake pad and rotor kit cannot be fitted to a carbon-ceramic car. On the facelift 4S, the standard V10 quattro runs 365 mm front rotors with eight-piston fixed calipers and 356 mm rear rotors with four-piston calipers. The V10 performance quattro comes standard with carbon-ceramic brakes: 380 mm front rotors with six-piston calipers and 356 mm rears. Carbon-ceramic rotors require their own specific pad compound and cannot be swapped for cast iron. That means a significant share of facelift R8s — every performance quattro — is simply not a candidate for the kits below, and no amount of "it says it fits 08-23 R8" changes that.

EBC's Stage 27 kit pairs Bluestuff NDX pads with fine-slotted rotor discs. Bluestuff is EBC's street-legal track compound: the company publishes a 0.52 friction coefficient and an operating range up to 550 °C (roughly 1,000 °F), and it is R90 approved for road use on most European fitments. What makes it the right pad for a street-driven R8 rather than a full race compound is cold bite — Bluestuff works from cold on the drive to the circuit, where a true race pad would not. EBC asks for about 200 miles of gentle street braking to bed the pads in; they ship pre-scorched, which shortens that considerably. Note that the kit NLP stocks is the front axle (part number S27KF1002).

Before we ship a Stage 27 kit to an R8 owner we ask for one photo: the front rotor through the wheel spokes. Carbon-ceramic rotors have a distinctly different, mottled grey face and typically wear ceramic-specific caliper markings, and a thirty-second look at that photo saves a customer from buying $1,158.95 of parts that will never fit their car. If you are shopping brakes for a V10 performance quattro, assume carbon-ceramic until you have confirmed otherwise.

To do the rear axle at the same time, the EBC 2-piece SG Racing rear rotors ($932.81) fit 2015-and-newer R8s. For owners who just want a better-than-stock replacement rotor without the track focus, the DFC drilled rear rotor ($843.70) is a straightforward OE-replacement upgrade: G3000/G11H18 high-carbon iron castings, the OE vane configuration for heat dissipation, Geomet corrosion coating, and mill-balanced to eliminate vibration.

Do You Need Bigger Injectors for a Supercharged or E85 R8?

A naturally aspirated, stock Audi R8 does not need bigger injectors — but a supercharged, turbocharged, or E85-converted one does, because the factory port injectors run out of flow once you add boost or switch to a fuel that needs roughly 30% more volume for the same air-fuel ratio. The Injector Dynamics ID1300-XDS flows 1,340 cc/min at 3.0 bar (43.5 psi) and handles up to 6.0 bar (87 psi) of differential fuel pressure. It is co-developed with Bosch Motorsport and is the only performance injector Injector Dynamics builds with all-stainless internals, which is precisely why it holds up to the corrosive nature of alcohol fuels. It is compatible with all known fuels, E85 included.

The ID1300-XDS set of 10 ($2,127.49, part number 1300.34.14.14.10) is sold as a matched set — one injector per cylinder on the V10 — and fits 2015–2022 R8 5.2 V10 and Lamborghini Huracán 5.2 V10 applications with no adapter connectors, which removes ten potential failure points from the install. One important caveat before you order: this part cannot ship to California under CARB regulations. Two things worth understanding about the Gen-2 R8 specifically: it uses factory dual injection (direct injection plus port injection), which is why the 4S is far less prone to intake-valve carbon buildup than the Gen-1 car, and why Gen-1 port-injection hardware kits do not fit the 4S manifold — the 4S already has port injectors from the factory. On the dual-injection 4S V10, this plug-and-play set of 10 drops into the port-injection side.

How Do You Make an R8 Louder Without Changing Drive Modes?

An exhaust valve control kit lets you open the R8's exhaust valves independently of Audi Drive Select, so you can have the loud exhaust without the aggressive throttle, gearbox, and damper maps that normally come bundled with it. From the factory, the 4S ties valve position to drive mode: the only way to hear the V10 properly is to put the whole car in Dynamic. That is a poor trade on a long highway drive, and an even worse one at 6 a.m. in a residential neighborhood, where Comfort mode still cannot make the car quiet on cold start.

The Akrapovic Sound Kit ($758.87, part number P-HF946) is exactly this — and it is worth being clear that it is not a muffler or a pipe. It is a receiver module that drives the actuators opening and closing the valves at the end of the exhaust system, controlled by a supplied Sound Remote Controller and by Akrapovic's smartphone app for iOS and Android. Quiet cruising in Dynamic, or full V10 in Comfort: the point is decoupling. It is listed for the R8 5.2 FSI Coupe and Spyder; confirm the fitment against your exact model year before ordering.

Audi R8 4S Model Years: What Actually Fits

The second-generation Audi R8 ran from US model year 2017 to 2023 — and there is no 2016 and no 2019 US model year. Audi skipped MY2019 in the States ahead of the facelift, which means the US facelift arrived as a 2020 car, not a 2019 one, even though the updated R8 was revealed in Europe in late 2018. Nearly every competing parts guide gets this wrong, and it matters: shopping a "2019 R8" part list will send you to the wrong catalog entries.

Pre-facelift cars (2017–2018) came as the R8 V10 quattro at 533 hp and 398 lb-ft, and the R8 V10 Plus at 602 hp and 413 lb-ft; 2018 also brought the rear-drive R8 V10 RWS at 532 hp. Facelift cars (2020–2023) are the R8 V10 quattro at 562 hp and the R8 V10 performance quattro at 602 hp at 8,100 rpm and 413 lb-ft at 6,700 rpm, good for 3.1 seconds to 100 km/h and 205 mph. The 2022–2023 V10 performance RWD makes 562 hp and 406 lb-ft. The send-off was the 2023 R8 GT RWD: 602 hp, an 8,700 rpm redline, 3.3 seconds to 60 mph, a 199 mph top track speed, and just 333 cars worldwide with 150 allocated to the US at $249,900. Curb weight across the range runs roughly 3,600–3,750 lb depending on trim and body style.

When you order suspension for one of these cars, the year is the easy part. The two questions that actually determine fitment are whether the car has magnetic ride and whether it has carbon-ceramic brakes. Our team in Tampa checks both before shipping an R8 suspension or brake kit — if you are unsure which options your car left the factory with, send us the VIN and we will confirm it against the build.
