Product Overview
TEIN Street Advance Z Lancia Delta Integrale Coilovers – VSG16-U1SA1
The TEIN Street Advance Z Lancia Delta Coilover Kit VSG16-U1SA1 is a specialist adjustable suspension package engineered for the iconic Lancia Delta HF Integrale Evoluzione.
Developed for the 1992–1995 Lancia Delta Integrale L31E5, this Street Advance Z Classic kit combines modern TEIN damper technology with a vehicle-specific design intended for one of the most celebrated four-wheel-drive performance cars of the 1990s.
With 16-way adjustable damping, threaded ride-height adjustment and carefully matched springs, the kit gives owners more control over suspension response and vehicle stance.
Whether restoring a classic Integrale, replacing ageing suspension or creating an individually configured performance build, the TEIN Street Advance Z Classic offers a complete coilover alternative to fixed-height replacement dampers.
Why Choose TEIN Street Advance Z Coilovers for the Lancia Delta?
1. 16-Way Adjustable Damping
A major benefit of the TEIN Street Advance Z Lancia Delta suspension kit is its 16-stage damping adjustment.
The adjustment mechanism lets drivers tune suspension response to suit their preferred balance of comfort and control.
Softer settings can help provide compliance over uneven roads, while firmer settings can produce a more controlled response under appropriate driving conditions.
The adjustment changes compression and rebound damping together.
For Lancia Delta Integrale enthusiasts, this flexibility is useful when balancing the car’s classic rally-derived character with road-driving requirements.
2. Adjustable Ride Height
The TEIN Street Advance Z Classic uses threaded spring seats to adjust the suspension height.
This allows owners to alter the car’s stance within the manufacturer’s specified adjustment limits.
For the Lancia Delta L31E5, TEIN lists a standard lowering figure of approximately 10mm at both the front and rear.
Its recommended lowering settings allow approximately 0–20mm below original ride height.
The manufacturer also publishes a wider mechanical adjustment range, but that should not be confused with the recommended range for safe, everyday use.
3. Matched Front and Rear Spring Rates
TEIN specifies the following spring rates for VSG16-U1SA1:
- Front: 6 kgf/mm (approximately 336 lb/in)
- Rear: 4 kgf/mm (approximately 224 lb/in)
These spring rates are matched to the suspension package and designed for the listed Lancia application.
The appropriate damping and ride-height settings should be selected together.
Simply choosing the lowest available height or firmest damping setting does not guarantee improved handling.
4. Twin-Tube Damper Construction
The Street Advance Z range uses twin-tube shock absorber construction.
This architecture is intended to provide controlled damping with a balance between road comfort and responsive suspension movement.
For older performance vehicles, worn dampers can contribute to bouncing, reduced body control and inconsistent handling.
Correctly installed replacement coilovers can help restore suspension performance, although the final result also depends on the condition of bushes, ball joints, mounting points and tyres.
5. Designed for the Lancia Delta HF Integrale Evoluzione
VSG16-U1SA1 is a vehicle-specific suspension package.
TEIN identifies the following application:
- Lancia Delta Integrale
- Chassis code L31E5
- 2.0L engine
- Four-wheel drive
- Production January 1992 to January 1995
This should not be interpreted as universal compatibility with earlier Delta Integrale 8V or 16V models, other Delta chassis or the later second-generation Delta.
Confirm the vehicle identity and original suspension configuration before purchasing.
6. Adjustable Suspension for Classic Car Restoration
Sourcing suspension components for older performance cars can become increasingly difficult.
TEIN’s Street Advance Z Classic range addresses selected historic and classic vehicles, providing application-specific suspension systems where suitable original replacement parts may be scarce.
This gives Lancia Delta Integrale owners an alternative to repeatedly rebuilding ageing factory components.
The coilover kit is especially relevant to vehicles undergoing a comprehensive suspension refurbishment.
7. Corrosion-Resistant Construction
TEIN incorporates protective coatings, dust boots and corrosion-resistant finishing across the Street Advance range.
These features help protect suspension components from environmental exposure.
For a valuable classic driven on UK roads, keeping adjustment threads clean and inspecting the suspension regularly remains important.
TEIN Street Advance Z vs EnduraPro+ Classic
TEIN offers two different suspension solutions for the Lancia Delta Integrale L31E5.
Street Advance Z Classic – VSG16-U1SA1
A complete coilover kit with springs, 16-way adjustable damping and ride-height adjustment.
EnduraPro+ Classic – VSG16-V1DS2
A replacement shock absorber kit featuring adjustable damping while retaining the intended original springs and factory ride height.
If you prefer to preserve the original suspension stance, see our TEIN EnduraPro+ Classic Shock Absorber Kit for Lancia Delta Integrale.
For customers seeking adjustable ride height as well as damping, Street Advance Z Classic is the more appropriate product.
Lancia Delta Integrale Ride Height Settings
TEIN’s manufacturer catalogue gives the following settings for this vehicle:
| Specification | Front | Rear |
|---|---|---|
| Standard height change | -10mm | -10mm |
| Recommended maximum height | 0mm | 0mm |
| Recommended maximum lowering | -20mm | -20mm |
| Spring rate | 6 kgf/mm | 4 kgf/mm |
These figures are measured relative to the original suspension height used by TEIN.
Actual ride height can vary depending on vehicle condition, trim, existing modifications and installation.
Stay within the manufacturer’s recommended setup range.
Will TEIN Street Advance Z Improve Lancia Delta Handling?
Correctly configured coilovers can provide more consistent suspension control and allow the vehicle’s ride height and damping characteristics to be tailored to its intended use.
However, suspension performance also depends on tyre quality, geometry, worn bushes and the condition of other chassis components.
For best results, inspect the full suspension system before installation and have the car professionally aligned afterwards.
Our Wheel Alignment Explained: Camber, Toe and Caster Guide covers the effect of lowered suspension on vehicle geometry and tyre wear.
You may also find our Anti-Roll Bar vs Strut Brace Guide useful when planning other handling upgrades.
