Sharper response without sacrificing daily drivability.
Designed to lower your BRZ approximately 25 mm front and rear, the Street Runner improves chassis response, body control, and overall driver confidence while maintaining the comfort expected from a daily-driven sports car.
Dežru Street Runner – Subaru BRZ / Toyota 86 / Scion FR-S (2013-2026)
The Dežru Street Runner suspension system was developed specifically for the Subaru BRZ chassis, a lightweight rear-wheel-drive platform known for its excellent balance, low center of gravity, and driver-focused handling characteristics.
Designed for drivers who want improved chassis control and sharper handling without stepping into the harsher territory of traditional track coilovers, the Street Runner delivers a more planted, responsive, and confidence inspiring driving experience while remaining comfortable enough for everyday use.
Built around a complete matched shock and spring package, the Street Runner utilizes 10-way adjustable twin tube dampers paired with carefully selected spring rates to improve body control, steering response, and transient stability during spirited driving.
Rather than relying on excessive spring stiffness, the Street Runner focuses on maintaining mechanical grip and predictable chassis behavior over real-world roads. This allows the BRZ to remain compliant and composed during daily driving while still feeling significantly tighter and more responsive during canyon driving, touge runs, and autocross use.
A moderate 25 mm front and rear lowering height improves center of gravity and visual stance while maintaining usable suspension travel and real-world drivability.

Performance Character
The Street Runner transforms the BRZ by reducing excess body movement and improving overall chassis composure while preserving the natural balance and drivability that make the platform so enjoyable.
Compared to the factory suspension, the Street Runner delivers sharper steering response, improved transition stability, and a more connected feel during aggressive driving while maintaining enough compliance for real-world roads and daily commuting.
The result is a BRZ that feels flatter, tighter, and significantly more confidence inspiring without becoming harsh or fatiguing during everyday use.
Why We Selected 171 lb/in Front & 238 lb/in Rear for the Subaru BRZ
The Subaru BRZ already has an exceptionally balanced chassis from the factory, so the goal of the Street Runner was not to overwhelm the platform with excessive spring stiffness, but instead improve control, responsiveness, and driver confidence while maintaining mechanical grip and ride quality.
The 171 lb/in front spring improves braking stability and steering response while reducing excessive front-end movement during turn-in and transitions.
The matching 238 lb/in rear spring improves rear support and stability during acceleration and corner exit while maintaining the playful and predictable handling balance the BRZ is known for.
Combined with the adjustable twin tube damping system, this spring configuration creates a suspension package that feels significantly tighter and more composed than stock while remaining compliant enough for real-world driving conditions.
This setup helps the BRZ:
- Reduce excess body roll and chassis movement
- Improve steering response and braking stability
- Increase rear stability during aggressive driving
- Maintain excellent daily driving comfort
- Deliver sharper handling without excessive harshness
Overall, the 171/238 spring configuration gives the BRZ a more responsive, planted, and confidence inspiring feel while preserving the balance and usability expected from a properly engineered street-focused performance suspension.
