Best Coilovers For Mazdaspeed 3: Compare 10 Suspension Kits

#1 · Best Overall

1. Godspeed MSS0680-B MonoSS

• Package Dimensions: 32 x 20 x 9 in
• Weight: 48 lb

Best for: BL-generation spring and damping tuning.

Why it ranks #1: Explicitly fits BL Mazdaspeed 3 models and combines 16 damping levels with independent spring-tension and ride-height adjustment.

Godspeed’s 8 kg/mm front and 5 kg/mm rear spring rates distinguish this MonoSS kit for 2010–13 BL Mazdaspeed 3 models. Sixteen rebound settings add a damping adjustment range, while independent ride-height and spring-tension settings give owners separate controls for configuring the suspension.

The 52mm monotube stainless-steel shock pairs with 16 rebound-force levels, allowing damping adjustment across the listing’s daily-driving-to-track range. Independent spring tension and ride-height adjustment let owners change those setup variables separately. The specified 8/5 kg/mm front/rear rates clarify the spring setup for buyers comparing suspension options. A Koyo Japan 6204z bearing in the internal piston is listed to provide a smooth stroke. This application is specifically the BL Mazdaspeed 3 from 2010 through 2013.

Skip it if you drive a 2007–09 BK Mazdaspeed 3; Godspeed MonoSS MSS0300-B is listed for that generation.

BL Mazdaspeed 3 owners wanting defined spring rates, adjustable rebound, and separate height and spring-tension controls are the best match. The listed application is 2010–13; BK-generation owners need a different fitment.

#2 · Best BK Fit

2. Godspeed MSS0300-B MonoSS

• Package Dimensions: 32 x 20 x 9 in
• Weight: 48 lb

Best for: BK chassis damping adjustability.

Why it ranks #2: Names BK Mazdaspeed 3 fitment and supplies 16 damping levels, independent height and spring-tension adjustment, and 7/4 kg/mm spring rates.

Sixteen rebound-force settings are the defining feature of Godspeed’s MonoSS kit for the 2007–09 Mazdaspeed 3 BK, letting drivers adjust damping across the listed daily-driving-to-track range. Independent spring-tension and ride-height adjustment also separate two setup tasks rather than tying them together.

The 52mm monotube stainless-steel shock and 16 damping settings give owners a way to tune rebound for different driving scenes, from daily use to Sunday track performance. Independent spring-tension and height adjustment allow ride height changes without using spring tension as the same setting. A Koyo Japan 6204z bearing in the internal piston is listed as providing a smooth stroke. The 7 kg/mm front and 4 kg/mm rear rates identify the supplied spring setup; application is specifically BK 2007–09.

Skip it if you have a 2010–13 BL Mazdaspeed 3; Godspeed MonoSS MSS0680-B lists that later-generation fit.

This kit suits BK-generation Mazdaspeed 3 owners who want adjustable rebound and separate height and spring-tension settings for street-to-track setup. Its stated application is 2007–09, so BL owners should choose a kit listed for their generation.

#3 · Included Links

3. FAPO Mazdaspeed Coilover

Best for: Lowering with sway links.

Why it ranks #3: Specifically lists Mazdaspeed 3 BL fitment and includes wrenches and sway bar links, with a stated 1-to-3-inch lowering range.

A 1–3-inch lowering range gives this FAPO RACING kit a clear stance-adjustment role, while included sway bar links add a chassis component to the package. Its stated fit covers Mazda 3 BL models from 2008–2013 and Mazdaspeed 3 BL models from 2010–2013, helping owners identify the relevant generation.

The height adjustment lets an owner target a lower stance within the stated 1–3-inch range, and FAPO says it can make the car more supportive. The included wrenches and sway bar links give the installation package more than coilovers alone. The listing also connects the setup with reducing turning noise and improving steering feel and response. Aluminum, spring steel, and rubber are the listed materials; confirm the model-year range carefully because the Mazda 3 and Mazdaspeed 3 spans differ.

Skip it if you own a BK-generation Mazdaspeed 3; Godspeed MonoSS MSS0300-B lists that 2007–09 application instead.

Mazdaspeed 3 BL owners seeking a moderate lowering range, included sway links, and the listed steering-response benefits are the intended audience. Its stated Mazdaspeed fit is 2010–2013, so it is not the listed choice for BK models.

#4 · Most Damping Levels

4. maXpeedingrods Adjustable Coilovers

• Weight: 62.5 lb

Best for: Multi-surface damper adjustment.

Why it ranks #4: Lists BK and BL Mazda 3 fitment including Mazdaspeed 3, with 24 damper levels and stated front and rear spring rates of 10 and 7 kg/mm.

Twenty-four damper levels, grouped by maXpeedingrods into street, mountain, and track ranges, make this kit notable for drivers who change their use case. Its listed Mazda 3 BK and BL coverage includes Mazdaspeed 3 and Mazda3 MPS, plus Mazda 5 CR applications.

The 0–8 street, 9–16 mountain, and 17–24 track guidance gives owners a practical starting point when changing damper settings for different roads or events. The listing says adjustments can be made at any time, so the setup can be revisited as use changes. A 10 kg/mm front and 7 kg/mm rear spring rate, with 7–10 mm preload, specifies the spring configuration. The listed Mazda 3 fit spans BK 2004–09 and BL 2009–13, including Mazdaspeed 3/MPS.

Skip it if you have a 2014–18 BM Mazda 3; D2 Racing RS lists that later chassis range.

Mazdaspeed 3 owners who want a broad damper range with suggested street, mountain, and track settings may appreciate the flexibility. The stated Mazda 3 coverage ends at BL 2009–13, so later BM owners need a different application.

#5

5. Godspeed MSS0680-B MonoSS Kit

• Package Dimensions: 32 x 20 x 9 in
• Weight: 49 lb

Best for: Rebuildable BL-generation MonoSS.

Why it ranks #5: Explicitly fits BL Mazdaspeed 3 and lists a 52 mm monotube shock, 16 damping levels, separate height and spring adjustment, and rebuildable shocks.

Rebuildability when worn gives this Godspeed MonoSS kit a maintenance feature beyond its 16 damping settings. Its stated fit is the 2010–13 BL Mazdaspeed 3, and independent spring-tension and ride-height adjustment let owners tune those setup variables separately.

The 52mm monotube stainless-steel shock includes 16 damping levels, giving drivers adjustment across the listing’s daily-driving-to-track range. Independent spring-tension and ride-height settings support separate setup changes, while the specified Koyo Japan 6204z internal-piston bearing is described as providing a smooth stroke. Racing-grade shock oil with a high viscosity index is also listed. When worn, the shock absorber can be rebuilt, offering a stated service path rather than requiring the entire unit to remain unserviceable.

Skip it if you drive a 2007–09 BK Mazdaspeed 3; Godspeed MonoSS MSS0300-B lists that earlier generation.

BL Mazdaspeed 3 owners seeking damping adjustment, separate height and spring-tension controls, and a rebuildable shock are the target buyer. Its listed fit is 2010–13, so earlier BK models are outside the stated application.

#6 · Fine Damping Range

6. Rev9 Hyper-Street II

• Package Dimensions: 32 x 20 x 9 in
• Weight: 54 lb

Best for: BK fit with 32-way rebound.

Why it ranks #6: Lists BK Mazda 3 fitment including Mazdaspeed, 32 damping settings, and independent spring-tension and ride-height adjustment.

Thirty-two rebound-adjustment clicks set Rev9’s Hyper-Street II apart for BK Mazda 3 owners, including the Mazdaspeed application. Independent spring-tension and ride-height settings let buyers address stiffness and vehicle height separately, while the listing specifies a 2004–09 BK fit.

The monotube shock’s steel-alloy body and valving work with 32 rebound settings, giving drivers a broad range for fine-tuning suspension response. Independent spring-tension and ride-height settings keep stiffness adjustment separate from lowering height, which can simplify setup decisions. Rev9 describes the monotube design as providing larger gas and oil capacity to improve comfort in a lowered vehicle. The listed 7 kg/mm front and 4 kg/mm rear rates define the spring setup; compatibility is limited to Mazda 3 BK 2004–09, including Mazdaspeed.

Skip it if you have a 2010–13 BL Mazdaspeed 3; Godspeed MonoSS MSS0680-B lists that later-generation fit.

BK Mazda 3 and Mazdaspeed owners who want extensive rebound adjustment and separate height and stiffness settings are the intended buyers. The stated application is 2004–09, so BL-generation owners need a different fit.

Listed on Amazon as: Rev9 R9-HS2-046 compatible with Mazda 3 (BK) 2004-09 Hyper-Street II Coilover Kit w/ 32-Way Damping Force Adjustment Lowering Kit, 32 Damping Level Adjustment, Ride Height Adjustable

#7

7. Tein Street Advance Z

• Package Dimensions: 35.43 x 11.81 x 11.81 in
• Weight: 56.4 lb

See also  Best Disposable Cups for Tea: Top 10 Picks

Best for: Early-generation Street Advance Z.

Why it ranks #7: The description specifies fitment for Mazdaspeed3 models in the earlier chassis range, though the supplied listing gives few adjustment details.

TEIN identifies this Street Advance Z coilover as fitting the 2004–09 Mazda Mazdaspeed3, making its early-generation application the clearest buying point. The supplied listing gives the model as GSM80-91AS3 and names the Street Advance Z line, but does not provide adjustment specifications to compare.

The stated 2004–09 fit directs this option to early Mazda Mazdaspeed3 owners rather than later generations. TEIN’s Street Advance Z line and GSM80-91AS3 model designation give buyers a specific product identity to match against their intended application. The supplied information does not describe spring rates, damping levels, or ride-height adjustment, so buyers cannot use those details here to plan a particular setup from the listing. Its core decision point is the named early-generation fit.

Skip it if you own a 2010–13 BL Mazdaspeed 3; Godspeed MonoSS MSS0680-B lists that later-generation application.

Owners of a 2004–09 Mazda Mazdaspeed3 looking specifically at TEIN’s Street Advance Z line are the relevant audience. The supplied fit description stops at 2009, so later BL models fall outside its stated application.

#8

8. Ksport Kontrol Pro

Best for: Fine damping control for 2010–13.

Why it ranks #8: Offers 36 damping settings and adjustable mounts, but the supplied fitment says 10–13 Mazda 3 without explicitly naming Mazdaspeed 3.

Thirty-six damping levels give Ksport’s Kontrol Pro a broad adjustment range for drivers balancing cruising comfort and handling preferences. The listing names 2010–13 Mazda 3 fitment and specifies pillowball upper mounts at the front and rear, supporting setup to OEM specifications.

Ksport says the 36 damping levels let users tune between a full-soft cruising setting and firmer preferences for handling, making adjustments relevant to both street and track use. Front and rear pillowball upper mounts are described as allowing installation and setup to OEM specifications. The 6061 aluminum spring perches, locking collars, and top mounts bring specified material strength to key adjustment components. The title identifies 2010–13 Mazda 3 fitment, so Mazdaspeed-specific application is not explicit in the supplied title.

Skip it if you need an explicitly named Mazdaspeed 3 application; Godspeed MonoSS MSS0680-B identifies the BL Mazdaspeed 3 by name.

Drivers seeking extensive damping tuning and pillowball mounts for the listed 2010–13 Mazda 3 fit may consider this kit. Because its supplied title does not explicitly name Mazdaspeed 3, verify the application details before choosing it.

#9

9. ATATKP Street Coilovers

• Weight: 50 g

Best for: Preassembled replacement shocks.

Why it ranks #9: Claims compatibility with BK and BL Mazdaspeed 3 and includes pre-assembled springs and mounts, but lists no damping adjustment or warranty.

Pre-assembled coil springs and mounts are the practical draw of this ATATKP suspension, with the listing saying they save installation labor. It is presented as a direct replacement for worn struts and lists Mazda Mazdaspeed 3 BL and BK applications spanning 2004–2013.

Because the coil springs and mounts arrive pre-assembled, the listing says installation can avoid assembling those components separately and describes the kit as bolt-on. Its shock absorbers are stated to absorb road bumps and vibrations, supporting a more controlled ride on commutes or road trips. The product description also says its damping reduces body roll in turns and nose-dive during braking. The fit wording spans BK 2004–09 and BL 2010–13, so owners should distinguish their chassis generation.

Skip it if you want a listed warranty; FAPO RACING’s BL coilover listing specifies a two-year manufacturer warranty.

Mazdaspeed 3 owners replacing worn struts who value pre-assembled springs and mounts are the target buyer. The listed application spans BK and BL years, while ATATKP specifies no manufacturer warranty.

#10

10. D2 Racing RS Coilovers

Best for: BM chassis wide-range damping.

Why it ranks #10: Lists 36-way damping and full ride-height adjustment, but its stated BM fitment is less clearly matched to the named Mazdaspeed 3 use case.

Thirty-six-way damping adjustment is the central feature of D2 Racing’s RS coilovers, giving owners a broad range for tuning the suspension. The listing identifies the application as a 2014–18 Mazda 3 BM including Mazdaspeed, and pairs the adjustable damping with full ride-height adjustment.

The 36-way damping range lets owners change shock settings to suit their preferred driving setup, while full ride-height adjustability provides a separate way to set vehicle height. Separate spring preload keeps that adjustment distinct from ride-height changes, supporting more controlled setup work. The listing also specifies monotube shock assemblies and anodized, powder-coated mounts with anti-rust coating on the strut threads. A setup video is noted among the additional facts. The stated fit is BM chassis, 2014–18, including Mazdaspeed.

Skip it if you own a 2010–13 BL Mazdaspeed 3; Godspeed MonoSS MSS0680-B lists that generation.

BM-generation Mazda 3 and Mazdaspeed owners seeking extensive damping adjustment and separate height and preload controls are the intended buyers. The listing identifies a 2014–18 BM application, so earlier Mazdaspeed generations are outside its stated fit.
