On the market, there is a lot of suspension that you can choose from. People often asked what are the different types of suspension system available for the Mazdaspeed 6.
There is 3 types of suspension: Lowering springs, coilovers or “bags”
There is also other Mazdaspeed 6 suspension parts like sway bar, end links and camber kits.
I personally buy the Yellowspeed and totally love them. Great quality of the component and great stiffness of the ride. Feel like OEM but with more responsiveness. I know a lot of people riding the Scale but I had a set and really hated it. If was not really built perfectly for the car like the Yellowspeed its more of a universal fit. I got rattle, problem to find the right spring rates and the quality was not the best even for the price.
Lowering Springs
AutoEXE Low Down Springs | Drop: 30mm | Part Number: MGS700
Spring Rates: Front 370 lb/in | Rear 225 lb/in
A full length height adjustable suspension kit that puts sports performance first with features like a hard setting mono tube damper and linear rate race spring, and an aluminum upper mount with enhanced bush. Without interfering with cooling performance, the newly developed thin ö40 piston reduces friction surface, which decreases friction during damper operation. This has the effect of facilitating uniform handling while simultaneously restricting discomfort. The damping force is adjustable in 12 levels. Overhaul is possible.
Eibach Pro-Kit | Drop: 1.5″ front, 1.4″ rear | Part Number: 5543.140
Spring Rates: Unknown (advertised as progressive)
The Eibach Pro-kit dramatically improves both a vehicle’s performance and appearance. The huge fender-well gap inherent from the factory or the installation of performance wheels and tires can give a vehicle a lifted look. The Pro-Kit is the perfect addition to any vehicle, lowering the fender gap and giving your ride a more attractive, sportier stance. By lowering the car’s center of gravity, the Pro-Kit reduces squat during acceleration, body roll in corners and excessive nose-dive under braking. When combined with Plus 1 or Plus 2 Size wheels and tires, the Eibach Pro-Kit is the finishing ingredient to a winning recipe for performance.
– Excellent ride quality – comfortable in cruising
– Sportive handling in cornering, resulting in improved performance
– Lowered center of gravity, increased stability
– Enhanced appearance of vehicle
– Million mile warranty
H&R Sport Springs | Drop: 1.4″ front, 1.3″ rear | Part Number: 52611

H&R Coilover Tunable Suspension | Drop: 1.2″-2.5″ front, 1.0″-2.3″ rear | Part Number: 29278-6
Spring Rates: Unknown
Dampened and tuned specifically for the all wheel drive MAZDASPEED 6.
H&R Threaded-Body Coil-Over Suspension Kits come directly from engineers who design and develop racing suspensions.
Blueprinted as coil-overs (not just a modified shock body), the H&R units are hand assembled in Germany by H&R Speziafedern under rigid ISO 9001 and German TÜV standards. Strict attention to the function of the complete suspension system is the number one design priority.
Their threaded body means that the outside of the strut or shock tubes are threaded like a bolt. This allows the threaded spring perch to be moved up or down to fine-tune the ride height, optimizing looks and handling.
Equally at home on the street or the track, H&R Coil-Over Suspension Kits provide enhanced performance, improved corner-holding ability and a sleek, aggressive stance for performance driving characteristics without harshness.
The Coil-Over Suspension Kits pictured above represent just a few samples of those available from H&R. Coil-Over Suspension Kits are engineered specifically for each vehicle and may combine different components than those pictured based on the vehicle’s design. Coil-Over Suspension Kits can be used for driving in weekend club sport events or lapping the public course at the Nurburgring.

KSport Kontrol Pro Coilovers
Spring Rates: Front 14K (784 lb/in) | Rear 3.7K (207 lb/in)
Ksport Kontrol Pro Fully Adjustable Coilover Kits provide the ultimate in suspension technology for your street or track car. 36 levels of damping adjustment allow you to fine tune the ride to your handling and comfort needs. The damping adjusts compression and rebound simultaneously for ease of adjustment. Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design. The pillow ball top mounts also allow you a more direct feel for solid driver response. Where available, camber canbe adjusted via the Pillow-ball Top Mounts, which means no additional “Camber Kits” are needed.
Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do. With the mounts and most pieces of the coilover being designed for 6061 billet aluminum the kit is lightweight, durable, and rust resistant. The steel shock body is electroplated with zinc to resist rust and the elements. The valving of each set is matched to the springs installed for unmatched ride quality and reliability.
The Ksport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube designs the Monotube dissipates heat better, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation are a lot less common in a Monotube design, which results in a better ride.
The Ksport Kontrol Pro Coilover kit has been designed with professional road racing in mind offering extremely high value and performance.

MONO TUBE INTERNAL DESIGN
15 month limited warranty on insert
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 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.
HIGH RIGIDITY STEEL SPRING
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.
ADJUSTABLE SPRING SEAT
In addition to the lower bracket, the vehicle ride height can be adjusted by the spring seat as well. The spring seats are made from forged aluminum for durability and rigidity.
SHOCK BODY
Shock body is coated with Electroplating treatment to prevent rust and corrosion.
FULL LENGTH ADJUSTABLE
A steel lower bracket is adopted on most MacPherson struts to increase rigidity for safety (some applications use aluminum lower brackets) , while a forged aluminum lower bracket on Double A Arm struts. The ride height can be adjusted by both lower bracket types without affecting the shock stroke.
DEVELOPED DAMPING OIL
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.
