Correct the Geometry First — Then Enjoy the Lowered Suspension

The Cobb Alignment Package - 2015-2021 Subaru WRX / STI (Inc. 2018 Type R / 2019 S209) for the 2015-2021 Subaru WRX STI corrects the suspension geometry changes that come with lowering the car. When the VA STI is dropped on coilovers or lowering springs, the front suspension geometry changes — roll center drops, and tie rod angles shift to produce bumpsteer through suspension travel. The Cobb kit addresses both issues, restoring proper geometry at the new ride height.

Why Geometry Matters After Lowering

Lowering a car without correcting roll center and bump steer produces a car that handles less predictably than stock despite sitting lower — the suspension geometry is working against the driver through every corner. The roll center correction raises the effective roll center back toward its stock relationship with the center of gravity, reducing body roll tendency. The bump steer correction realigns the tie rod geometry to minimize toe change through suspension travel, producing more linear steering response.

Bolt-In Correction — Works With Any Lowering Setup

The Cobb kit installs at the factory suspension mounting locations on the VA STI — no modification to the knuckle, strut, or chassis. It's compatible with any lowering setup that moves the suspension through the geometry ranges the kit corrects for.

Straight From Subispeed

This is one of the most overlooked upgrades on lowered VA STI builds. The handling improvement from correcting roll center and bump steer geometry is often more noticeable than the coilover upgrade itself — and it's bolt-in. If you've lowered your VA STI and it doesn't feel as sharp as you expected, there's a good chance this is why.

About Cobb Tuning

Cobb Tuning has been developing performance parts and tuning solutions for Subaru vehicles since 1999. Based in Austin, Texas, Cobb built their reputation on the Accessport — the most widely used Subaru ECU tuning device on the market — and expanded that into a full ecosystem of intake, exhaust, drivetrain, and engine bay accessories engineered specifically for the platforms they support. Every Cobb product is developed in-house and validated on their own test vehicles before it reaches customers. Subispeed carries the full Cobb catalog because their engineering standards and platform-specific development process consistently produce parts that work exactly as advertised.
