Best Audi R8 (Type 42) Coilovers: KW V3 vs H&R RSS+

Audi R8 (Type 42) coilovers are height-adjustable, damping-tunable suspension kits that replace the factory struts on the first-generation 2008–2015 R8 to sharpen handling, drop ride height, and fix the compromises of the aging OEM magnetic ride dampers. The two names R8 owners keep coming back to are KW and H&R — and the single kit that best balances street comfort, track capability, and magnetic-ride compatibility is the KW Variant 3. This guide compares the KW V3, KW V4, and H&R RSS+ head-to-head with real spring rates, lowering ranges, and prices, so you can spend your money once and get it right.

Why Upgrade the Audi R8 (Type 42) Suspension?

The first-generation Audi R8 rides on a double-wishbone aluminum suspension with an optional Audi Magnetic Ride (MRC) damper system. It is a brilliant chassis, but after 10 to 18 years the factory magnetic dampers lose their tune, leak, and cost thousands to replace per corner — often more than a full aftermarket coilover kit. Upgrading to coilovers solves three problems at once: it restores precise damping, it lets you lower the R8's high-riding factory stance by up to nearly an inch, and it gives you a corner-balanceable platform for track days.

At NLP Performance, the questions we field most from R8 owners in our Tampa, FL shop are about magnetic-ride compatibility and dashboard warning lights. That is the single biggest buying decision on this car: the mid-mounted 4.2L V8 (420–430 hp) and 5.2L V10 (525–550 hp) cars were both offered with and without MRC, and the wrong kit will either not fit or will trigger a permanent suspension fault code. Get the fitment right and a Type 42 R8 transforms from a soft, nose-high GT into a flat, planted supercar.

KW V3 vs H&R RSS+ vs KW V4: R8 Coilovers Compared

All three of these coilovers are genuine, race-derived kits — but they target different buyers. The KW V3 is the do-everything street-and-track kit. The H&R RSS+ is a lighter, track-leaning monotube at a lower price. The KW V4 is the flagship with separate high- and low-speed compression tuning, the same platform KW uses on hypercars. Here is how the numbers stack up for the Type 42 R8.

KW Variant 3: The Best All-Around R8 Coilover

The KW Variant 3 is the coilover we recommend to the widest range of Type 42 R8 owners. It is the only kit in this comparison that carries a single part number covering all engines and all suspension configurations, including cars fitted with Audi Magnetic Ride. That matters: on an MRC car, this version (part number kws35210101) ships with the EDC delete integration built in, so you avoid the dashboard fault code that non-MRC kits trigger.

Mechanically, the V3 uses KW's stainless steel “inox-line” struts, which will never rust or seize the threads — a real concern on a car this expensive to service. Damping is genuinely independent: 16 clicks of rebound (KW's TVR-A valving) control body motion and rebound feel, while 12 clicks of low-speed compression (TVC-A) let you dial grip and turn-in without touching rebound. Lowering runs from 0.0 to 0.8 in. at the front and up to 0.9 in. at the rear, with spring rates of roughly 570 lb/in front and 740 lb/in rear that keep the ride firm-but-livable on Florida's less-than-perfect roads.

H&R RSS+ Coil Over: The Track-Focused Value Pick

The H&R RSS+ is the value play for the driver who spends more weekends on track than commuting. It undercuts the KW V3 by nearly $3,000 at $4,005 (marked down from $4,450) and uses a race-style monotube shock in a lightweight, black hard-anodized aluminum body. Where the KW V3 splits rebound and compression into two separate adjusters, the H&R RSS+ uses a single 12-position knob that tunes rebound and compression together — simpler to set, and plenty for most track-day drivers.

KW Variant 4: The No-Compromise Flagship

If money is no object and you want the sharpest possible R8, the KW Variant 4 is the flagship. At $8,774 it is the most expensive kit in this guide, and it earns it: the V4 adds separately adjustable high-speed and low-speed compression damping on top of independent rebound, the same multi-way race technology KW deploys on cars like the Lamborghini Aventador SV and Mercedes-AMG GT. This is the tool for a dedicated track R8 where you want to tune the front axle's reaction to curbs and big bumps independently of body roll.

The Magnetic Ride Question (and Why It Decides Your Kit)

Audi Magnetic Ride is the single most important fitment factor when buying Type 42 R8 coilovers. If your R8 came with MRC, removing the factory electronic dampers without addressing the wiring throws a permanent suspension fault code and a dashboard warning light. There are two clean solutions: buy the KW V3 “w/ magnetic ride” kit, which builds the fix in, or add a KW Electronic Damping Cancellation Kit alongside a non-MRC coilover such as the KW V4 or H&R RSS+.

Budget Alternative: H&R Sport Springs

Not every R8 owner needs a full coilover. If your factory dampers are still healthy and you just want to close the wheel gap and lower the center of gravity, H&R Sport Springs are the entry point at $424.15 (down from $499.00). These are progressive-rate lowering springs that bolt onto your existing OEM shocks, delivering a modest, fixed drop and a firmer, more planted feel without any electronic complexity. It is the smart first mod for a street-driven Type 42 R8 on a budget.

How to Choose Coilovers for Your R8 (Type 42)

Choose your Type 42 R8 suspension by how you drive and whether you have magnetic ride. For a street-and-track daily that must stay code-free on MRC, the KW Variant 3 is the safest, most versatile buy. For a track-first build on a non-MRC car where value matters, the H&R RSS+ delivers most of the performance for nearly $3,000 less. For an uncompromising track weapon, the KW Variant 4 is the flagship. And for a budget street drop on healthy OEM dampers, H&R Sport Springs are the entry point.
