Product Specifications
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
