Built for the 2015-2021 Subaru WRX (VA1) and WRX STI (VA2), this Street Series coilover kit delivers a planted, aggressive stance with the red anodized shock body that pops behind your wheels. Unlike the previous-generation GE/GV platform where WRX and STI used different strut designs, the VA platform shares the same strut mounting geometry — so this single kit fits both WRX and STI.
The pillow ball front top mounts eliminate strut flex under hard cornering, giving you sharper steering response and more precise turn-in — a real performance advantage over OE rubber mounts. The twin-tube damper paired with 55CrSi cold-bent coil springs (10 kg/mm front / 8 kg/mm rear) keeps the ride composed for daily driving while controlling body roll and brake dive. The red anodized shock body features an anti-corrosion coating for year-round durability in winter and salt conditions.
Drops your WRX or STI 1-3 inches from factory ride height via the threaded spring perch. Aluminum upper components reduce unsprung weight; carbon steel lower brackets handle the structural load. Fits VA sedan only (2015-2021) — no hatchback was offered on the VA platform. If you want a daily-driven WRX or STI that handles like it should have from the factory, this is your kit.
Key Features
- Red Anodized Shock Body with Anti-Corrosion Coating — Signature red finish that stands out behind your wheels; anodized + anti-corrosion coating for winter/salt durability
- 1-3 Inch Adjustable Lowering Range — Threaded spring perch lets you dial in the exact stance; drops from factory ride height, not from OE sport height
- Pillow Ball Front Top Mounts — Eliminates strut flex under cornering; sharper steering response and more precise turn-in compared to OE rubber mounts
- Twin-Tube Damper System — Longer stroke and smoother ride than mono-tube; reduces joint pressure and minimizes friction for comfortable street driving
- 55CrSi Cold-Bent Coil Springs — High-rigidity chrome-silicon steel springs; 10 kg/mm front / 8 kg/mm rear, calibrated for VA WRX/STI weight distribution
- Weight-Saving Aluminum Components — Aluminum upper mounts and spring perches reduce unsprung weight; carbon steel lower brackets handle structural load
- Direct Bolt-On Replacement — No fabrication, no cutting; uses factory mounting points on both WRX (VA1) and STI (VA2)
- 1-Year Manufacturer Warranty — Backed by Flashark's quality guarantee; email service@flasharkracing.com for support
- Full Hardware Kit Included — 2 C-spanner adjustment wrenches and all pictured mounting hardware in the box

Pro Tip: The VA platform (2015-2021) shares the same strut mounting geometry between WRX (VA1) and WRX STI (VA2) — this kit fits both. No hatchback was offered on the VA platform; all VA WRX/STI are sedans. To confirm your exact model, check the production date on the driver's door jamb sticker and the model designation on your registration (WRX vs. WRX STI).
Q: Does this kit fit both the WRX and WRX STI on the VA platform?
A: Yes. The VA platform (2015-2021) shares the same strut mounting geometry between WRX (VA1) and WRX STI (VA2). This single kit fits both — sedan only, no hatchback on VA.
Q: Was the VA WRX offered as a hatchback?
A: No. Subaru discontinued the WRX hatchback after 2014. The 2015-2021 WRX and WRX STI (VA platform) are sedan only. This kit fits all VA sedans.
Q: How low can I drop my WRX/STI with this kit?
A: The kit provides 1-3 inches (25-75 mm) of lowering from factory ride height via the threaded spring perch. Most owners run 1.5-2 inches for a clean street look. Going to 3 inches may require checking tire clearance, camber adjustment, and adds stress to CV axles.
Q: What is a pillow ball top mount, and why does it matter?
A: A pillow ball (mono-ball/spherical bearing) top mount replaces the flexible rubber bushing with a precision metal bearing. This eliminates strut flex under cornering — sharper steering response and more precise turn-in. Trade-off: slightly more road noise vs. rubber mounts. This kit: pillow ball front, standard rubber rear.
Q: Are the front camber plates adjustable?
A: No. This kit uses fixed pillow ball front top mounts — camber is not directly adjustable. For camber correction after lowering, use aftermarket camber bolts or adjustable front control arms (sold separately). See our Track Series for camber-adjustable pillow ball top mounts.
Q: Are the dampers adjustable? How do I tune them?
A: No, the dampers are non-adjustable (fixed valving) — factory-tuned for a balanced street/light-track ride. For adjustable damping, see our Track Series (32-way) coilovers.
Q: What is the spring rate, and is it right for my driving style?
A: 10 kg/mm (560 lbs/in) front and 8 kg/mm (448 lbs/in) rear 55CrSi springs. Stiffer front / softer rear bias matched to VA WRX/STI weight distribution; helps reduce AWD understeer. Balanced street rate — noticeably firmer than stock. For serious track builds, consider Track Series.
Q: What is 55CrSi spring steel, and why is it better?
A: 55CrSi is a chrome-silicon alloy spring steel with high rigidity and excellent fatigue resistance. Cold-bent manufacturing work-hardens the steel for better rate retention and less sag over time vs. hot-wound springs. Commonly used in performance and motorsport coilovers.
Q: Do I need to cut or modify anything to install these coilovers?
A: No cutting or fabrication required. Direct bolt-on replacement for factory struts and rear shocks on both WRX (VA1) and STI (VA2). Allow 4-6 hours for a full install on a lift. Professional alignment is required after install.
Q: Do I need an alignment after installing coilovers?
A: Yes — a 4-wheel alignment is required after installation. Front camber/toe and rear toe/camber set to spec. Expect $80-150 at a shop experienced with modified Subarus. Re-check after 500 miles once coilovers settle.
Q: Will the red anodized body fade or corrode over time?
A: The shock body is red anodized with an additional anti-corrosion coating for road salt and winter protection. Anodized aluminum is highly durable. Avoid harsh chemicals (acidic wheel cleaners, degreasers). Clean with mild soap and water; inspect annually for chips and touch up exposed metal.
Q: Will these coilovers fail my state inspection / DMV check?
A: In most U.S. states, coilovers are legal if minimum ride height is maintained (typically 6-8 inches fender-to-tire, varies by state). We recommend 1-2 inch drop (legal in nearly all states). Check your state's ride height laws. Not DOT/SAE certified — install at owner's discretion.
