Street Basis Z Series:

The Tein Street Basis Z series is designed for enthusiasts who want improved handling and adjustable ride height without the complexity and cost of fully adjustable coilovers. The fixed damping is carefully tuned by Tein's engineers to provide the optimal balance of comfort for daily driving and performance for spirited driving. This makes the Street Basis Z perfect for street cars that see occasional spirited driving but aren't dedicated track cars.

Fully Adjustable Ride Height:

The Street Basis Z coilovers feature fully adjustable ride height with independent front and rear adjustment. This allows you to dial in the perfect stance for your preferences - whether you want a subtle drop for daily driving or maximum lowering for show use. The adjustment mechanism is designed to maintain spring preload throughout the adjustment range.

Fixed Damping - Street Tuned:

Unlike adjustable damping coilovers, the Street Basis Z features fixed damping that's pre-tuned by Tein for optimal street performance. This eliminates the guesswork of damping adjustment and ensures you get a well-balanced setup right out of the box. The damping is firm enough for spirited driving but comfortable enough for daily use.

Twin-Tube Shock Design:

Tein uses a twin-tube shock design for the Street Basis Z series. This design provides reliable, consistent performance for street use while keeping costs accessible. The twin-tube design is proven and durable, making it ideal for daily driven vehicles.

Why Lower Your GS?

• Improved Handling: Lower center of gravity reduces body roll and improves weight transfer
• Aggressive Stance: Fills wheel wells for purposeful, VIP-inspired appearance
• Reduced Wheel Gap: Eliminates unsightly gap between tire and fender
• Enhanced Cornering: Improved chassis dynamics and reduced roll
• VIP Style: Perfect for the classic VIP sedan look

Height Adjustment Range:

The Tein Street Basis Z coilovers typically offer:

• Front: Adjustable lowering up to 2.5 inches
• Rear: Adjustable lowering up to 2.5 inches
• Note: Actual range may vary based on vehicle and setup

Why Tein?

Tein has been engineering high-performance suspension components for over 30 years, with deep roots in Japanese motorsport and street performance. Their coilovers are proven on race tracks and streets worldwide, delivering consistent, reliable performance. Every Tein product is manufactured in Japan to the highest quality standards.

Perfect Pairing:

For the ultimate suspension setup, pair the Tein coilovers with:

• Upgraded sway bars for reduced body roll
• Camber arms for improved alignment adjustability
• Performance alignment for optimized geometry
• Quality tires to maximize grip and handling

Installation Tips:

• Professional installation strongly recommended - coilover installation requires specialized tools
• Alignment Required: Get a professional alignment after installation
• Start with moderate lowering and adjust from there
• Allow coilovers to settle for 100-200 miles before final height adjustment
• Check ride height periodically and adjust as needed

Alignment Considerations:

After installing lowering coilovers, a professional alignment is essential. The lowered ride height changes suspension geometry, and proper alignment ensures optimal tire wear, handling, and steering feel. Consider a performance alignment with slight negative camber for improved cornering.

VIP Style:

The Lexus GS is a classic VIP sedan platform, and the Tein Street Basis Z coilovers are perfect for achieving that aggressive VIP stance. Lower your GS to fill the wheel wells, pair with quality wheels, and enjoy the timeless VIP aesthetic.

Perfect For:

• GS300, GS400, and GS430 owners seeking improved stance and handling
• Daily drivers who want comfort and performance balance
• VIP enthusiasts building classic VIP sedans
• Anyone wanting quality Japanese coilovers at accessible pricing
• Street cars that see occasional spirited driving

Perfect For: Lexus GS owners seeking the perfect balance of improved handling, adjustable stance, and daily drivability with proven Tein quality.

Pro Tip: Start with moderate lowering for daily driving - the Street Basis Z damping is optimized for street comfort at reasonable ride heights.
