The Dynamic Pro Sport Coilovers are engineered for Lexus IS300 owners seeking excellent handling performance without sacrificing daily driving comfort. Designed for street-focused enthusiasts with occasional track use in mind, this suspension system delivers a refined balance of ride quality, responsiveness, and adjustability. Each kit is hand-built to order and road-tested to ensure consistent performance and durability.

Balanced Sport Suspension Design: Tuned for daily driving and spirited use, providing improved handling and stability while maintaining a comfortable ride quality compared to aggressive track-oriented setups.

Performance-Tuned Spring Rates: Front 14k and rear 8k spring rates offer a well-balanced setup that reduces body roll and improves cornering while keeping rear compliance for everyday drivability.

33 Levels of Damping Adjustment: One-way damping adjustment allows simultaneous rebound and compression tuning through a single dial, making it easy to tailor ride feel for street or track conditions.

Full-Length Ride Height Adjustment: Ride height is adjusted independently of spring preload using the lower bracket, allowing the vehicle to be lowered at least 2.5 inches on most applications while retaining maximum suspension travel and proper shock stroke.

Aluminum Upper Mounts with Rubber Bushings: Aluminum upper mounts with hardened rubber bushings help reduce noise, vibration, and harshness while maintaining durability and consistent performance.

Optimized Lower Bracket Design: MacPherson strut applications utilize reinforced steel lower brackets for increased rigidity and safety, with brake line brackets welded directly to the mount. Double A-arm applications use high-quality forged aluminum lower brackets. All brackets receive electroplated or anodized surface treatment for corrosion resistance.

Improved Suspension Travel: Lower bracket height adjustment allows ride height changes without compromising damper stroke, maintaining comfort and performance even at lowered settings.

Quality-Tested Construction: Each application is test-fitted and fully road-tested to ensure reliability, stability, and consistent ride quality.
