Super Low Version KitCoilover Application

For those people who have limited budge on their purchase, but they want their vehicles to look cooler and to go further lower, especially demo car in the show/exhibition, SUPER LOW VERSION kit is an ideal choice compared to Air Suspension kit. With a Dynamic Pro Sport kit, the vehicle ride height can be lowered about 60mm – 100mm from factory (varies per application). For the SUPER LOW version kit, it enables to offer an additional 20mm ~ 30mm drop over the Dynamic Pro Sport kit. In other words, you can go down to 80 - 130mm from factory with SUPER LOW VERSION kit (depending on the application) by replacing shock insert or lower bracket or spring or other components (depending on the application). Please note the SUPER LOW VERSION kit will increase the ride handling but may make you feel a decrease in ride comfort. For safety reason, a vehicle with this SUPER LOW VERSION KIT driven at high speed is NOT recommended. * Super Low Version Kit is a special order and is made on demand; the lead time would be about 7 – 10 business days.


This suspension system features 33-way dampening force adjustment (compression/ rebound). A wide range of dampening adjustments can be made to provide a variety of responses to different road conditions and to tune the ride feel.

Newly improved rear dampening adjustment method for most Audi & VW models (rear sustech upside-down strut design)

In some Audi & Volkswagen or other vehicle makes applications, the dampening can not be adjusted on the rears without shock removal, which was found in our previous design and other brands. This caused so much inconvenience and time waste to the driver who desired perfect ride feel. With excessive testing & constant improvement, newly improved rear dampening adjustment method design is available now; you can just easily adjust the rear dampening to your preference setting without shock removal from your lovely car every time unlike other brands utilizing the old design still!!

Available models:

A3(8P).A3 Quattro(8P).A4(B6).A4 Quattro(B6).A4(B7).A4 Quattro(B7).A4(B8).A5(B8).A5 Quattro(B8).A6(4F).A7.RS4 Quattro(B7).RS6 Quattro(4F).S3(8P).S4(B8).S5(B8).TT(8N) 2WD.TT(8J).TT Quattro(8J).TTS Quattro(8J).TT RS Quattro (8J)

The pillow ball mount with camber plate is included on the front and the rear to offer direct and complete handling response (not available for some applications). Squeaking noise may occur in rare cases from the shock absorbers and this is normal, hence the product warranty does not cover any noise issue. Most suspension kits are fitted with pillow ball upper mounts to improve handling; however, pillow balls on some applications may create rattling sound (metal-to-metal sound, and this can be found on other brands as well). This is normal and it does not affect the product’s performance. The product warranty does not cover any rattling sound issue caused by the pillow balls. For those people who dislike the slight noise caused by the pillow ball, we also offer hardened rubber upper mount for noise reduction and enhancement of ride comfort and handling stability. In addition, the pillow ball is consumptive product such as bearing, brake pads, brake rotor, oil seal etc.., and it will be worn out after having been used for a certain period; therefore, if you need to replace the worn pillow ball, you can purchase it from us.


3 month limited warranty on insert
Shock inserts will be replaced with shorter ones than Dynamic Pro Sport kit to maximize lowering capabilities (depending on the application). The needle valve piston (material imported from Sweden) is utilized to make the steering more agile and to stabilize the vehicle. A high rigidity 52mm shock body (for MacPherson strut type) with extra oil capacity enables the cushioning force to have optimal linear change. We use highly reputable seal brand – NOK, whose seals can withstand high temperatures and prevent oil leakage. The piston rod is made from high quality S45C steel and is processed with Thermal Refining and High-frequency Induction Hardening Treatments for rigidity and durability. YELLOW SPEED’s commitment is to ensure safety and to provide high quality products, hence the shock stroke movement has been tested 10 million times on advanced testing equipment; this amount of testing is equal to a vehicle with 5-years of mileage. Each component of the suspension system is rigorously inspected and strictly tested by YELLOW SPEED to avoid any failure. Our commitment to continual driving improvement goes beyond words.


Spring bearing is mounted between the spring and the top cap to make the handling more agile and to eliminate the spring noise caused by car cornering. This design enables the spring and the shock to perform together more effectively. Clean and grease the spring bearing periodically to prevent from rust or corrosion, which can make the spring bearing last longer.


Springs will be replaced with shorter ones than Dynamic Pro Sport kit to maximize lowering capabilities (depending on the application). The spring is made from high quality SAE9254 steel for optimal durability and high tensile strength. The spring rate remains unchanged and undeformed even after the spring has been subjected to long term wear and even if compressed or extended.


The spring seats are made from forged aluminum for durability and rigidity.


Shock body is coated with Electroplating treatment to prevent rust and corrosion.


Lower brackets will be replaced with shorter ones than Dynamic Pro Sport kit to maximize lowering capabilities (depending on the application). A steel lower bracket is utilized for MacPherson strut type to increase rigidity for safety (where applicable). For some MacPherson strut models, the brake line bracket is welded manually perfectly to the steel lower mount. A high quality forged alloy aluminum lower bracket is used for Double-A Arm strut type (where applicable). The steel/aluminum lower bracket is processed with electroplated/ anodized surface treatment to prevent corrosion or rust in the harsh conditions of motor sport. The vehicle ride height can be adjusted easily with the lower bracket by winding up and down to drop and raise. With the lower bracket, it allows maximum suspension travel without affecting the shock stroke.


It is made from forged 6061 aluminum for increased strength and rigidity.


Our formula damping oil contains high quality deformer to prevent foaming, and the viscosity remains unchanged under any working temperature conditions to ensure that all internal components perform perfectly.

Wave Alloy Steel Thrust Washer

For FRONT MacPherson strut models, wave alloy steel thrust washer is installed between a lower locking collar and a bottom mount. The wave thrust washer can provide a controlled amount of friction between the lower locking collar and the bottom mount to effectively prevent the lower bracket from spinning around or becoming loose.
