Yellow Speed Racing Inverted Premium Comp Coilovers – 2015-2021 Subaru WRX / STI

Yellow Speed Racing Inverted Premium Comp Coilovers – 2015-2021 Subaru WRX / STI

Premium Competition Specification With Inverted Front and Rear
The Yellow Speed Racing Inverted Premium Comp coilovers bring the track-tuned spring rates and valving of the Premium Competition line together with a fully inverted monotube design on both front and rear dampers. The 55mm inverted shock body increases fluid capacity for sustained track use heat management, improves shaft seal longevity, and provides greater structural rigidity than standard monotube construction — all in a package calibrated for competition-level driving.

Application Notes

• Fits 2015+ WRX & STI Models
• Please select desired front & rear upper mount style (See note below)

Full Inverted Monotube Front and Rear
Unlike the Inverted Pro Street which uses the inverted design only on the front, the Inverted Premium Comp runs the inverted monotube configuration on all four corners. This provides consistent damper characteristics and structural benefits across the full suspension system. The aluminum ring seal design on all dampers resists corrosion and debris damage for competition durability.

Upper Mount Options
Both front and rear upper mount styles are selectable at order. Front options: rubber or pillowball with camber plates. Rear options: pillowball or pillowball with camber plates. Select the configuration that matches the build’s use case — rubber for street, pillowball for dedicated track alignment.

Why Choose Yellow Speed Racing
Yellow Speed Racing has been engineering suspension systems since 2003, with development rooted in competitive motorsport. Their coilovers are used across circuit racing, drift competition, rally, and time attack globally. Every kit is hand-assembled to order, with vehicle-specific valving and fitment validated through real-world testing. The Inverted Premium Comp combines Yellow Speed’s competition spring and damping specification with the durability advantages of a fully inverted monotube system.

The RallySport Take

The Inverted Premium Comp is for builds where both performance and damper longevity under sustained track use matter. The combination of Premium Competition spring rates and fully inverted monotube construction is the right spec for frequent track days, time attack, or any application where the standard monotube’s heat management limits are a concern. Select upper mount configuration at order to match the intended alignment setup.
