Yellow Speed Racing Pro Plus Racing Coilovers – 2008-2014 Subaru STI

Competition-Derived Suspension for Serious Track Use
The Yellow Speed Racing Pro Plus Racing coilovers are developed from extensive research, engineering, and actual competition use. Fine-grained suspension tuning is essential at this level, and the Pro Plus Racing delivers it — available in 2-way (independent rebound and compression) and 3-way (independent high-speed compression, low-speed compression, and rebound) configurations to match the specific demands of the driver and event. Stiffer spring rates and race-grade valving place this kit firmly in the competition category.

Application Notes

• Front Lower Mount Clevis Width = 30mm
• Fits 08-14 STI Sedan & Hatchback Models Only

2-Way and 3-Way Adjustable Configurations
The 2-way configuration provides independent rebound and compression adjustment — the right choice for most track day and club racing applications. The 3-way configuration adds separate high-speed and low-speed compression adjustment, allowing drivers to tune for both mechanical grip over bumps and body control through sustained cornering independently. Select the configuration at time of order.

Race-Grade Components Throughout
High-quality components are specified throughout the Pro Plus Racing kit with durability and consistency under competition conditions as the primary criteria. Each application is test fitted and validated before release.

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 Pro Plus Racing line reflects Yellow Speed’s competition experience applied to a kit designed for drivers who take track performance seriously.

The RallySport Take

The Pro Plus Racing is for builds that live at the track. The 2-way is the more versatile choice for track days and occasional street use; the 3-way is the right call for dedicated competition builds where independent high/low-speed compression tuning is needed. Above this in the Yellow Speed lineup is the Advanced Pro Plus Racing, which adds motorsport-grade damper specifications for the highest levels of competition.
