Which Yellow Speed Racing Coilovers Are Right for Me?

Quick answer: If you drive the car on the road and take it to the occasional track day, the Dynamic Pro Sport is the one — a 33-way adjustable, full-length height adjustable coilover that does everything well. If you want one set that is properly good on both street and track, with compression and rebound adjusted separately, the 2-way or 3-way Club Performance is the all-rounder with external reservoirs. If the car is a dedicated race car, look at the Premium Competition (single adjuster, race-grade hardware) or the 2-way or 3-way Pro Plus Racing. If you want the car sitting on the floor for looks, Super Low is a Dynamic Pro Sport built to drop 80–130 mm — for show cars, not daily drivers. If you drift, YSR make a dedicated drift range, and if you rally there are long-travel gravel dampers — Dynamic Pro Gravel Rally (1-way) and Advanced Pro Plus Gravel Rally (2-way/3-way) — and a 2-way/3-way Advanced Pro Plus Tarmac Rally for asphalt stages. Everything below explains what those differences actually mean on the car.

Yellow Speed Racing (YSR) is one of the biggest names in coilovers for Japanese and European performance cars, and one of the best value for money ranges out there. The catch with a range this wide is that the names alone tell you very little. Here is how we would choose.

What a coilover actually gives you

A coilover is a damper and a coil spring built as one unit, with a threaded body so you can set ride height independently of spring preload. Compared with a set of lowering springs on standard dampers, you get three things: control over ride height, a damper that is actually valved for the spring rate it is paired with, and — on every YSR kit — adjustable damping, so the same set can be softened for the road and stiffened for the track.

Start with what the car is for

Before you look at any product, be honest about the car's job. A road car that sees two track days a year has very different needs from a car that lives on a trailer. The questions that decide it:

• How much of the time is the car on the road? A road car needs comfort, sensible spring rates and top mounts that do not rattle. A race car does not care.
• How much adjustment will you really use? A single adjuster is enough for most drivers. Separate high-speed and low-speed compression is only worth paying for if you (or your engineer) will actually set it up corner by corner.
• What is the budget? YSR cover a wide range of price points. The cheapest kit that does the job properly is a better buy than the most expensive one you never adjust.

Dynamic Pro Sport — the all-rounder

The Dynamic Pro Sport is YSR's best-selling coilover and the one we recommend to most customers. It uses a monotube damper with 33 clicks of combined compression and rebound adjustment, full-length height adjustment (ride height is set on the lower bracket, so lowering the car does not eat into the damper's travel), and aluminium top mounts. Depending on the application, the front top mounts are pillow ball with adjustable camber plates, or hardened rubber bushes for a quieter road car.

Spring rates are chosen for a fast road car rather than a race car, which is exactly why it works so well as an everyday kit: set the damping in the middle for the road, wind it up for a track day or a time attack session, and wind it back down for the drive home.

Best for: daily-driven performance cars, fast road use, occasional track days and club time attack.

Raced in: Time Attack and club-level track series.

Super Low — a Dynamic Pro Sport that sits on the floor

Super Low is a revised Dynamic Pro Sport built for one thing: ride height. Where a standard Dynamic Pro Sport lowers the car by a sensible amount, Super Low sits 80–130 mm below factory ride height — shorter bodies, shorter springs, the same 33-click adjuster. It is the answer for a stanced show car that wants to sit on the ground without the cost and complexity of air ride.

Be clear about what you are buying. That much drop means very little suspension travel, geometry well outside what the car was designed for, and a car that scrapes on speed bumps, driveways and ferry ramps. YSR do not recommend Super Low for a daily-driven car, and neither do we — it is a show-and-cruise coilover, not a performance one.

Best for: show cars and stance builds that have to sit very low without air ride.

Premium Competition — single adjuster, race hardware

The Premium Competition keeps the same 33-way adjuster and full-length height adjustment as the Dynamic Pro Sport, but everything around it is built for racing. The lower mounts are lightweight aluminium alloy to cut unsprung weight, MacPherson-strut applications get pillow ball top mounts as standard, and many applications use an inverted strut — the damper body sits at the top and the thicker section takes the side loads, which makes the whole assembly considerably stiffer under cornering loads.

This is the coilover that front-running cars in one-make Honda series such as the Type R Trophy and Civic Cup, and club endurance cars, have been racing on for years. Spring rates are race-oriented, so we would not put it on a car that still has to be pleasant on the road.

Best for: dedicated race cars where a single, well-valved adjuster is enough.

Raced in: Type R Trophy, Civic Cup (front-running cars), FNduro club endurance.

Club Performance — 2-way and 3-way for street and track

Club Performance is the step into multi-way damping. It comes as a 2-way (compression and rebound adjusted separately) or a 3-way (high-speed compression, low-speed compression and rebound all adjusted separately), with an external reservoir on each damper. The reservoir does two jobs: it gives the nitrogen gas charge its own space so the damper runs more consistently when hot, and it carries the compression adjusters.

On the 3-way the adjustment range is 50 clicks of high-speed compression, 24 clicks of low-speed compression and 33 clicks of rebound. That is a lot of range, and the point of it is that you can run a genuinely compliant road setting and a stiff track setting on the same hardware — soften high-speed compression for potholes, add low-speed compression for body control on track.

Best for: cars that have to do both — driven on the street, driven hard at track days — and anyone who wants to learn proper damper setup.

Used for: street, track days and club level racing.

Pro Plus Racing — the top of the range

Pro Plus Racing is YSR's professional-level damper, again available as 2-way or 3-way with external reservoirs. The 3-way carries the same 50 / 24 / 33 click ranges as the Club Performance, but the valving, internals and materials are their motorsport specification — this is the product YSR develop and test with their race programmes, and it is what you will find on cars in series like the M3 Cup and Club Enduro.

Be realistic about this one. A 3-way damper only pays off if it gets set up properly, ideally with data or a good engineer. On a car that just needs to be stiff and predictable, a Premium Competition set and the price difference spent on tyres will be faster.

Best for: competition cars with a setup programme behind them.

Raced in: M3 Cup, Club Enduro.

Drift coilovers

Drifting is a different problem. The car spends its life at full lock and full throttle, with the front suspension loaded sideways in ways a circuit car never sees, and it gets hit — by kerbs, by clipping points, by other cars. YSR's drift-specific coilovers are built around that: stronger construction, valving suited to rapid weight transfer, and specifications developed with professional drifters. They are available for the usual suspects — S-chassis, Skyline, BMW E36/E46/E9x, Supra, and so on.

YSR run drivers at the top of the sport on this hardware — Forrest Wang, Karolina Pilarczyk, Pauly C and Andy Frost among them — in Formula Drift and the Drift Pro Championship.

Best for: drift cars, from grassroots to competition.

Raced in: Formula Drift, Drift Pro Championship.

Gravel Rally — Dynamic Pro (1-way) and Advanced Pro Plus (2-way / 3-way)

Gravel is the opposite problem to the circuit. Instead of lowering the car and stiffening it, you need ground clearance, long travel and a damper that survives jumps, ruts and rocks. The Dynamic Pro Gravel Rally is YSR's answer: a 1-way (33-click) monotube damper in a heavy-duty 55 mm body, with an inverted insert on MacPherson-strut fronts so the fat outer body takes the side loads and keeps brake heat away from the damping oil. Travel is long — close to factory stroke — and the height adjustment goes up, typically 40 mm or more above standard depending on the application. Spring rates are soft by circuit standards (4–6 kg/mm), because the car has to soak up the surface rather than fight it.

Front top mounts are aluminium pillow ball with camber plates on most applications; hardened rubber mounts are available where you want less noise on a car that is also driven on the road.

Above it sits the Advanced Pro Plus Gravel Rally: the same long-travel, raised-height, inverted-front concept, but with YSR's motorsport-spec damper and an external reservoir, as a 2-way (compression and rebound separate) or a 3-way (high-speed compression, low-speed compression and rebound). This is the one for a proper stage rally or rallycross car, where you want to run soft high-speed compression for the rocks and jumps while keeping enough low-speed compression to stop the car wallowing under braking and turn-in. Same gravel-friendly spring rates, same raised ride height, pillow ball camber-plate fronts as standard.

Best for: Dynamic Pro Gravel Rally for club rally, rallycross and forest-road cars; Advanced Pro Plus Gravel Rally for competition stage rally cars that get set up per event.

Raced in: stage rally and rallycross championships.

Advanced Pro Plus Tarmac Rally — 2-way and 3-way for asphalt stages

Tarmac rally and hill climb sit somewhere between circuit and gravel: sealed surface and high grip, but bumpy, cambered public roads with crests and compressions a race track never has. The Advanced Pro Plus Tarmac Rally is YSR's motorsport-grade damper valved for exactly that. It comes as a 2-way (compression and rebound separate) or a 3-way with an anodised external reservoir; the 3-way gives 17 clicks of high-speed compression, 20 clicks of low-speed compression and 33 clicks of rebound. Spring rates are firm (typically 8–12 kg/mm) and the front runs pillow ball top mounts with camber plates as standard.

If you do closed-road events, hill climbs or sprint rallies on asphalt, this is the range to look at rather than a circuit damper — the valving is built for keeping the tyre on a rough road at speed, not for a smooth track.

Best for: tarmac rally cars, hill climb and sprint cars, asphalt stage rallies.

Raced in: tarmac rally championships, hill climb and closed-road events.

Jargon buster: what the adjusters actually do

1-way adjustment

One knob per damper, adjusting compression and rebound together. Turn it up and the whole damper gets firmer; turn it down and it gets softer. Simple, and for most drivers it is all the adjustment they will ever use.

High-speed compression

"High speed" refers to how fast the damper shaft is moving, not how fast the car is going. High-speed compression is what happens when the wheel hits something sharp — a pothole, a kerb, an expansion joint — and the damper has to compress a long way very quickly. Stiffer high-speed compression means the car sits flatter over big hits and the tyre stays loaded, at the cost of comfort. Softer lets the wheel move out of the way of the bump, which is smoother and often faster on a rough surface, but the car can feel less tied down.

Low-speed compression

Low-speed compression covers the slow, large movements — the nose diving under braking, the body rolling into a corner, the rear squatting under power. This is the adjuster that controls how the car feels. More low-speed compression resists roll and dive, so the car responds faster to steering input and stays more level; too much and it feels harsh and skips over bumps mid-corner. Less gives a calmer, more compliant car that takes a fraction longer to settle.

Rebound

Rebound controls how quickly the damper extends again after it has been compressed — how fast the spring is allowed to push the wheel back down. More rebound slows the extension: fewer oscillations, a tighter feel, better control over crests. Too much and the suspension "packs down" over successive bumps because it never fully recovers, and the tyre can lose contact. Less rebound lets the wheel follow the road more freely and rides more comfortably, but the car can feel floaty at speed.

How to choose

Decide what the car is for, then buy the simplest coilover that does that job well. For a road car that gets used hard, the Dynamic Pro Sport. For a show car that has to sit on the ground, Super Low — and not for the daily. For a race car on a single adjuster, the Premium Competition. For a car that needs to be genuinely good on both road and track, or that you want to learn setup on, a Club Performance 2-way or 3-way. For a competition programme, Pro Plus Racing. For drifting, the drift range. For rally, the Dynamic Pro Gravel Rally or Advanced Pro Plus Gravel Rally on loose surfaces and the Advanced Pro Plus Tarmac Rally on asphalt. And if you are between two, ask us — we fit and set up YSR coilovers in our workshop and can tell you what has worked on cars like yours.

Frequently asked questions

Are Yellow Speed Racing coilovers good for daily driving?

The Dynamic Pro Sport is designed for it. Set the damping around the middle of the range and it is a firm but comfortable fast-road setup. The competition ranges use race spring rates and are not intended for daily use.

What does "33-way adjustable" mean?

The adjuster has 33 clicks between fully soft and fully stiff. On the 1-way ranges it changes compression and rebound together; on the 2-way and 3-way ranges 33 clicks is the rebound range alone.

What is the difference between 2-way and 3-way coilovers?

A 2-way adjusts compression and rebound separately. A 3-way additionally splits compression into high-speed and low-speed, so you can tune the response to sharp bumps and to body roll independently.

What is full-length height adjustment?

Ride height is set by moving the whole damper body up or down in the lower mounting bracket, rather than by winding the spring seat down. The damper keeps its full travel at any ride height, so you do not lose bump travel by lowering the car.

Do I need camber plates?

On MacPherson-strut cars, adjustable camber plates let you add negative camber for track use. Many Dynamic Pro Sport and all Premium Competition strut applications include pillow ball top mounts with camber adjustment; check the specific application.

How low do Super Low coilovers go?

Super Low sits 80–130 mm below factory ride height, depending on the application. It is a Dynamic Pro Sport revised for maximum drop, aimed at show and stance cars as an alternative to air ride. YSR and we do not recommend it for daily-driven cars.
