Features
![Adjustable Spring Seat](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-5_0.jpg)
Adjustable Spring Seat
The spring seats are made from forged aluminum for durability and rigidity.
![Shock Body](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-6_0.jpg)
Shock Body
Shock body is coated with Electroplating treatment to prevent rust and corrosion in the harsh conditions of motorsport.
![33-Way Dampening Adjustable](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features_0.jpg)
33-Way Dampening Adjustable
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.
![Pillow Ball Upper Mount With Adjustable Camber Plate](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-2_0.jpg)
Pillow Ball Upper Mount With Adjustable Camber Plate
For suspension systems utilizing a MacPherson strut type, the pillow ball mounts with adjustable camber plates are included fronts and rears (where applicable) to offer direct and complete handling response. 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.
![Monotube Inverted Design](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-3_0.jpg)
Monotube Inverted Design
For the suspension system with front or rear MacPherson strut model, the monotube inverted design is utilized to reduce the effect upon the damping oil and shock piston resulting from high temperature from the brake system and to take side loading better without major deflection. The damper rod is made up-side down to save unsprung weight for better suspension response. The inverted strut is built stronger than a regular shock due to different shock body construction with an outer sleeve. For the suspension system with rear A-Arm strut model, the rear damper rod has been thickened to 20mm, which enables to support a bit more side G Force, and makes a vehicle more stable. In addition, the thickened damper rod can prevent from being bent or deformed.
![High Rigidity Steel Spring](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-4_0.jpg)
High Rigidity Steel Spring
All springs are produced from high quality SAE9254 steel for optimal durability and high tensile strength. The spring rate and shape remains unchanged and undeformed, even if the spring has been subjected to long term wear.
![Full Length Adjustable](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-7_0.jpg)
Full Length Adjustable
For most 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 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.
![Lower Locking Collar](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-8_0.jpg)
Lower Locking Collar
It is made from forged 6061 aluminum for increased strength and rigidity.
![Developed Damping Oil](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-9_0.jpg)
Developed Damping Oil
Yellow Speed 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](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-10_0.jpg)
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.
![Spring Bearing Top](https://ic.carid.com/yellow-speed-racing/items/premium-competition-features-11_0.jpg)
Spring Bearing Top
Spring bearing top is mounted under the pillowball mount 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.
