Description

RS-R Part Number: XNSPT558MP

The RS-R Sports*i Club Racer Coilovers for the Toyota GR Corolla are a competition-focused suspension system engineered to deliver maximum handling performance, precise ride-height control, and track-ready damping characteristics while maintaining refined road manners.

Developed by RS-R’s motorsports engineering program in Japan, the Club Racer series is designed for drivers who demand sharper turn-in, reduced body roll, and improved chassis control compared to stock suspension or entry-level coilovers. This system transforms the GR Corolla into a more responsive and predictable performance platform, whether on the street or track.

If you’re searching for GR Corolla coilovers, this kit represents one of the most advanced suspension upgrades available for the G16E-GTS platform.

Key Benefits of RS-R Club Racer Coilovers

Upgrading to high-performance coilovers provides significant improvements in handling, adjustability, and overall driving dynamics:

• Sharper steering response and improved cornering stability

• Reduced body roll and improved weight transfer

• Adjustable ride height for stance and performance tuning

• Advanced damping control for street or track setups

• Increased grip and chassis precision

Unlike basic lowering springs, the RS-R Club Racer system allows full suspension tuning to match driving style, tire setup, and performance goals.

Engineering and Performance Design

The RS-R Sports*i Club Racer system is engineered as a complete suspension solution using track-focused spring rates and adjustable dampers.

Spring Rates

• Front: 10.0 kg/mm

• Rear: 13.0 kg/mm

These rates provide a firm, performance-oriented balance designed to maximize grip and chassis stability under aggressive driving conditions.

Ride Height Adjustment

Recommended adjustment range:

• Front: -10 mm to -55 mm (-0.4″ to -2.2″)

• Rear: -15 mm to -65 mm (-0.6″ to -2.6″)

Preset ride height drop:

• Front: -30 mm to -35 mm (-1.2″ to -1.4″)

• Rear: -35 mm to -40 mm (-1.4″ to -1.6″)

Maximum adjustment range:

• Front: 0 mm to -90 mm

• Rear: -15 mm to -65 mm

These ranges allow precise tuning of ride height for both performance and aesthetics.

Damping Adjustment

• 36-way adjustable dampers (front and rear)

This wide adjustment range allows drivers to fine-tune suspension stiffness for street driving, track use, or competition setups.

Construction and Quality

RS-R Club Racer coilovers are built using high-quality materials and manufacturing processes:

• Monotube damper design for consistent performance

• Vehicle-specific valving tuned for the GR Corolla

• Precision-machined mounts and brackets

• Hand-assembled coilover components

• Motorsport-grade durability and reliability

These features ensure consistent damping performance under high-load driving conditions.

Fitment

• Toyota GR Corolla (2023+)

• Chassis code: GZEA14L

Designed specifically for the GR Corolla platform for direct bolt-on installation.
