Our Verdict
For the 2016–2023 Audi R8 (Type 4S), the KW HLS with V4 coilover is the ultimate suspension upgrade — 4-way adjustable damping plus a hydraulic front-axle lift — while Eibach and H&R lowering springs deliver a cleaner stance for a fraction of the cost.
Choose coilovers if you want adjustable ride height and track-ready damping; choose lowering springs if you want to keep Audi’s adaptive dampers and Magnetic Ride. The single most important question is whether your R8 has the adaptive suspension option — it decides which parts fit.
Shop Our Top Pick →Upgrading the suspension on a 2016–2023 Audi R8 (Type 4S) is the single most effective way to sharpen how the 5.2L V10 supercar turns, stops, and sits. This Audi R8 coilover and lowering-spring comparison puts five in-stock options head to head — from the flagship KW HLS with V4 coilover (around $14,600) down to Eibach and H&R progressive springs (in the $420–$550 range). The 4S R8 makes between 532 and 612 horsepower depending on trim and weighs roughly 3,600 lb, so the right springs or coilovers pay off in both grip and looks. Below, our Tampa, FL team breaks down what each system does, which R8 it fits, and how to pick.
Coilovers vs. Lowering Springs for the Audi R8: What’s the Difference?
Coilovers replace the R8’s entire strut — damper and spring — and let you dial in ride height (and, on adjustable models, damping). Lowering springs keep the factory dampers and simply drop the car on a stiffer, shorter progressive spring. Coilovers cost more and take longer to install, but they unlock adjustable stance and track-grade control; springs are the affordable path to a lower, tighter look while preserving Audi’s adaptive dampers.
On a mid-engine, all-wheel-drive R8 (RWD on later Performance trims), suspension changes are felt immediately: body roll drops, turn-in gets crisper, and the lowered center of gravity plants the quattro system out of corners. Because this is a $150,000-plus exotic, we only stock name-brand systems — KW, H&R, and Eibach — that are engineered specifically for the Type 4S chassis.
Does Your R8 Have Audi Adaptive Suspension (Magnetic Ride)?
This is the fitment question that matters most. The Type 4S R8 was sold with two suspension setups: a passive sport suspension and an optional Audi adaptive (magnetic) suspension with electronically controlled dampers. Parts are cataloged differently for each:
- Cars WITHOUT adaptive suspension can run standard lowering springs (Eibach Pro-Kit, H&R Sport Springs) or a coilover conversion (H&R RSS+).
- Cars WITH adaptive suspension need parts that either retain the magnetic dampers — like the KW Height Adjustable Spring (HAS) kit — or delete/replace them entirely, like the KW HLS/V4 coilover. H&R also offers an adaptive-compatible RSS+ variant.
Check your build sheet or the damper struts before ordering. If you’re unsure, our team can confirm fitment by VIN.
The 5 Best Audi R8 (4S) Suspension Upgrades In Stock
Here are the five R8 4S suspension systems we stock, ordered from the flagship track weapon to the budget-friendly stance spring. Every price below live-updates from our catalog, and each links straight to the product page.
The KW HLS hydraulic front-axle lift integrated with the V4 4-way adjustable coilover for the Audi R8 4S.
The KW HLS with V4 is the no-compromise choice. The Variant 4 coilover offers four-way independently adjustable damping — separate high- and low-speed compression plus rebound — so you can tune the R8 for street comfort or track precision. Bolted to it is KW’s Hydraulic Lift System (HLS), which raises the front axle by up to roughly 45 mm at the push of a button to clear driveways and speed bumps. The stainless “inox-line” body resists corrosion for the life of the car. At around $14,600 it is priced like the exotic it fits, but nothing else on this list matches its breadth of adjustment.
The H&R RSS+ coilover is a monotube, damping-adjustable system that brings coilover-level ride-height adjustment at roughly a quarter of the KW HLS price (around $4,000, down from $4,450). It is engineered specifically for R8 4S cars without adaptive suspension; H&R sells a separate adaptive-compatible RSS+ variant (about $4,600) for cars that keep the magnetic dampers. Expect a firmer, flatter, more connected feel than any spring-only setup.
The KW HAS kit lowers the Audi R8 4S on adjustable springs while retaining the factory adaptive dampers.
The KW HAS kit is the smart middle ground for cars with Audi adaptive suspension. Instead of replacing the magnetic dampers, it uses height-adjustable helper springs on the OEM struts, so you keep the factory ride-comfort modes while dialing in a lower, adjustable stance. At around $1,900 it costs a fraction of a full coilover and preserves the R8’s adaptive damping character.
The Eibach Pro-Kit is the enthusiast’s value pick: a set of four progressive-rate springs that lower the R8 approximately 0.8 in (about 20 mm) front and rear while working with the factory dampers. Progressive rates keep daily ride quality civil, and the kit is backed by Eibach’s Million Mile Warranty. It’s currently in the $500–$550 range and, at publish time, carries an extra 5% off.
The H&R Sport Springs are the most affordable way to drop your R8, at around $425 (down from $499). Progressive-rate coils lower the car roughly 0.9 in for a purposeful stance and reduced fender gap, without the harshness of a fixed-rate race spring. They’re built for 4S coupes without adaptive suspension and carry H&R’s limited lifetime warranty.

Which Audi R8 Suspension Upgrade Should You Buy?
Track days and total control: the KW HLS with V4 is the answer — adjustable damping for any circuit plus a front lift so the splitter survives the paddock. Serious street/canyon use without the flagship price: the H&R RSS+ coilover delivers adjustable height and firmer damping for around $4,000. Adaptive-suspension cars that want to stay adaptive: the KW HAS kit lowers the car and keeps Magnetic Ride. Best value stance: Eibach Pro-Kit or H&R Sport Springs drop the R8 for under $600 while retaining the factory dampers.
H&R progressive-rate Sport Springs are the most affordable way to lower an Audi R8 4S.

Installation and Alignment Notes
Lowering springs on a 4S R8 are typically a 3–5 hour job because the dampers must come out to swap the coils; coilovers take similar time plus setup for ride height. Any of these upgrades changes camber and toe, so a professional 4-wheel alignment afterward is essential — both to protect the pricey Pirelli tires and to keep the quattro system tracking straight. Budget for corner-balancing on the adjustable systems (KW HLS, H&R RSS+, KW HAS) to get the most from them. Explore the full range on our suspension collection.
Frequently Asked Questions
Should I buy coilovers or lowering springs for my Audi R8?
Buy coilovers if you want adjustable ride height and track-grade damping; buy lowering springs if you want a lower stance while keeping the factory dampers and adaptive suspension. Coilovers like the KW HLS with V4 (around $14,600) or H&R RSS+ (around $4,000) add adjustability; springs like the Eibach Pro-Kit or H&R Sport Springs lower the car for under $600 on the OEM struts.
Will lowering springs work with Audi adaptive suspension (Magnetic Ride)?
Standard lowering springs are cataloged for R8 4S cars without adaptive suspension. If your R8 has Audi adaptive (magnetic) suspension, use a kit designed to retain the magnetic dampers — such as the KW Height Adjustable Spring (HAS) kit — or a coilover that fully replaces them. Always confirm which suspension your car left the factory with before ordering.
How much does it cost to upgrade the suspension on a 2016-2023 Audi R8?
R8 4S suspension upgrades range from about $424 for H&R Sport Springs to $14,594 for the KW HLS with V4 coilover. Eibach Pro-Kit springs run around $549, the KW HAS kit about $1,864, and the H&R RSS+ coilover about $4,005. Add a professional alignment (typically $150–$300) to any install.
What is the KW HLS and why does it cost $14,594?
The KW HLS with V4 combines a Variant 4 coilover — with four-way independently adjustable compression and rebound damping — and a Hydraulic Lift System that raises the front axle by up to about 45 mm on demand. It is the most adjustable and feature-rich R8 4S suspension available, which is why it is priced as a flagship, track-focused system.
How much can you lower an Audi R8 (Type 4S)?
Lowering springs drop the R8 4S roughly 0.8 to 1.0 inch (about 20–25 mm): the Eibach Pro-Kit lowers it approximately 0.8 in and H&R Sport Springs about 0.9 in. Coilover systems such as the KW HLS/V4, H&R RSS+, and KW HAS offer an adjustable drop so you can set the exact ride height you want.
Can you keep a nose-lift function on a lowered R8?
Yes. The KW HLS with V4 includes a hydraulic front-axle lift that raises the nose by up to roughly 45 mm at the touch of a button to clear driveways, ramps, and speed bumps, then returns to your set ride height — a major advantage on a low-slung exotic with an expensive front splitter.
