Yellow Speed Racing Coilovers: Every Series Compared (2026)
By Mike Dalton · · 9 min read

Yellow Speed Racing (YSR) makes coilovers in about a dozen series, from the street-focused Dynamic Pro Sport to external-reservoir race kits, drift kits, gravel rally kits and air struts. For most street cars the Dynamic Pro Sport is the default pick; the other series trade comfort, price or ride height for a specific job.
Most Yellow Speed Racing coilovers on our store cost $999 to $2,500, with a handful of circuit kits at $2,795. We list over 1,500 YSR kits, and you can browse them all on our Yellow Speed Racing page or compare other brands in coilovers.
What is Yellow Speed Racing?
Yellow Speed Racing, often shortened to YSR, sells coilovers and suspension parts in the US through Yellow Speed Racing USA. The brand's US product pages say it stocks kits in an El Paso, Texas warehouse, while built-to-order kits come from its manufacturing center in Taiwan. The brand describes all of its coilovers as hand built and made to order for each application.
The drift line has a notable backstory. YSR says its Dynamic Pro Drift coilovers came from a development project with members of Japan's Nichiei Racing Team: Yoichi Imamura, who won the Japan D1 championship in 2003, 2009, 2010 and 2011, and Feng Ren Zhi, a D1 professional driver from Taiwan.

The Drift Spec count includes two kits titled Dynamic Pro Drift. We also carry a few YSR extras such as camber kits, a suspension arm kit and a replacement spanner wrench set.
Dynamic Pro Sport
YSR's core kit and our biggest series. YSR calls it ideal for daily driving and occasional track use. You get 33-way damping and full-length ride height adjustment, set on the lower bracket without eating into shock stroke.
Pillowball mounts with adjustable camber plates come front and rear on most kits. Some use aluminum uppers with hardened rubber bushings for less noise. The brand says most applications can drop at least 2.5 inches. MacPherson strut cars get a steel lower bracket; double A-arm cars get a forged aluminum one.
Examples: Subaru Impreza and WRX (GD), Audi A3 (8P) and BMW Z4 (E89).
Inverted Pro Street
YSR describes this as the Dynamic Pro Sport idea with a 55mm inverted monotube shock body. YSR says the inverted design resists side loads, keeps brake heat away from the damping oil and cuts unsprung weight. Damping is 33 levels, with rebound and compression on one knob, adjusted from the bottom of the coilover.
Where the rear can't be adjusted in place, YSR includes its Rear Sustech damper with the dial at the bottom. Many kits offer rubber or pillowball front uppers; YSR warns pillowball can add significant noise.
Examples: Lexus ES300 (XV20) and Mercedes 190 (W201).
Premium Competition
Premium Competition is built for cars that see track events and competition often. YSR says it uses stiffer spring rates than the Dynamic Pro Sport plus larger valving, still with 33-way damping and full-length height adjustment. Lower mounts are lightweight aluminum, and MacPherson strut cars get pillowball top mounts. The Inverted Premium Comp version adds a 55mm inverted front body and comes with rubber front uppers as standard.
Examples: Subaru STI 2008-2014, Toyota MR2 (SW20) and Nissan Skyline (R34).
Club Performance
Club Performance is the step into external reservoirs. The reservoir adds oil capacity to shed heat, and YSR pitches it at drivers who do occasional track days but still drive the car daily.
You order it as 2-way (separate rebound and compression) or 3-way. The 3-way version splits compression into 17 clicks of high-speed and 20 clicks of low-speed, plus 33 clicks of rebound. MacPherson strut kits include radial bearings and front pillowball camber plates where applicable.
Examples: Subaru WRX and STI 2015-2021 and Nissan 240SX (S13).
Super Low
Super Low is for looks. YSR says it adds about 30mm of drop over the Dynamic Pro Sport, for 80mm to 130mm below factory ride height depending on the car. YSR says it may hurt comfort and does not recommend high-speed driving at a low setting. Some kits need body trimming, and at least one requires welding.
Examples: Honda Civic 2001-2005 and Toyota Camry 2002-2006.
Pro Plus Racing
Pro Plus Racing is YSR's race kit for frequent track events. Like Club Performance it uses an external reservoir in 2-way or 3-way form, with the same click counts on the 3-way. Above it sits the Advanced Pro Plus Circuit Spec, which YSR calls its top-tier circuit kit and says is not recommended for street use.
Examples: Subaru WRX 2008-2014, Nissan 240SX (S14/S15) and the Acura RSX Circuit Spec.
Dynamic Pro Drift Spec
The kit developed with the Nichiei Racing Team drivers. YSR lists inverted dampers, reinforced lower mounts and helper springs where applicable, with spring rates matched to the valving. It is a 1-way kit with 33 levels of damping.
Examples: BMW 3 Series (E36), Mazda MX-5 (NC) and Nissan 370Z.
Dynamic Pro Gravel Rally
The gravel kit goes the other way from most coilovers: YSR says it keeps shock travel close to OEM length and raises the car 1.5 inches or more at its tallest setting, depending on application. It uses 55mm shock bodies, inverted on MacPherson struts, and 33 levels of damping. Hardened rubber front uppers are standard.
Examples: Subaru Impreza (GC) and Honda Civic Si (EP3).
Dynamic Pro Air Struts
These are air struts with adjustable damping, not coilovers. YSR lists up to 5 inches of drop on most vehicles, 33 levels of damping, 1/4 in or 3/8 in air line fittings, and 5 to 100 psi operating pressure. YSR says the struts work with most air management systems, which you buy separately. If you're deciding between air and coilovers, read air suspension vs coilovers first.
Examples: Honda Accord 2013-2017 and Toyota Camry 2018-2024.
Which YSR series should you buy?
- Daily driver: Dynamic Pro Sport. Step up to Inverted Pro Street for the inverted body.
- Track days: Club Performance if the car is still your daily, Premium Competition if you want firmer single-adjustable springs and valving, and Pro Plus Racing for frequent events where separate compression and rebound matter.
- Drift: Dynamic Pro Drift Spec. YSR developed it for drivers in drift competition, with spring rates matched to the valving.
- Slammed or show: Super Low for a static drop on a budget, or Dynamic Pro Air Struts if you want to air up for driveways and air out at the show.
- Rally and gravel: Dynamic Pro Gravel Rally. It is the only series built to keep travel and add height.

Fitment notes before you order
YSR kits are vehicle specific, and many listings ask you to choose options. These are the notes that come up most often in the brand's descriptions:
- Front strut diameter: some kits ask you to select your OEM front strut diameter. On one Dynamic Pro Sport kit, 50mm applications get 7k front springs and 55mm applications get 8k.
- Rear design: some cars offer a divorced rear (shock and spring separate) or a true coilover rear. YSR notes that true coilover rears require trimming the vehicle body on those kits, and spring rates differ between the two options.
- Electronic damping: YSR says vehicles with electronic damping may need a cancellation module to prevent a warning light. Some kits mention an iSweep canceller with an OE-type plug; others list an optional EDC cancellation kit.
- Drive layout and body: many kits fit only AWD, FWD or RWD versions, or exclude convertibles, so check the application note.
- Upper mounts: YSR says pillowball mounts improve steering response but can add noise, and recommends rubber where offered if noise matters.
- Modified cars: YSR designs kits around OEM components and does not guarantee fit with aftermarket or modified parts.
After install, set your height and damping with our how to adjust coilovers guide, check wheel clearance with the ride height and fitment calculator, and get an alignment. Warranty terms come from the brand.
