Product Overview
TEIN Flex Z Coilover Kit for Honda Integra DC5 and Acura RSX
The TEIN Flex Z Coilover Kit VSA02-C1SA1 is a complete height-adjustable suspension upgrade developed for the Honda Integra DC5 Type R and compatible Acura RSX models.
Combining 16-way damping adjustment, full-length ride-height control and vehicle-specific upper mounts, the TEIN Flex Z offers a versatile suspension solution for drivers who want improved control over their vehicle’s stance and handling characteristics.
Designed with real-world road usability in mind, the Flex Z range uses twin-tube dampers to balance responsive suspension movement with ride comfort over uneven surfaces.
Whether you’re restoring a tired DC5 suspension, lowering your Honda Integra Type R or building a capable fast-road car, this adjustable coilover kit provides a comprehensive suspension upgrade.
Why Choose the TEIN Flex Z Coilover Kit?
1. 16-Way Adjustable Damping
The TEIN Flex Z VSA02-C1SA1 features 16-stage damping adjustment, allowing drivers to change the suspension’s firmness to suit different road conditions and driving preferences.
Compression and rebound damping are adjusted together using the integrated adjustment mechanism.
Softer settings may provide improved compliance on uneven roads, while firmer settings can help create a more controlled feeling during spirited driving.
The appropriate setting depends on tyre choice, ride height, road conditions and the overall suspension setup.
2. Full-Length Adjustable Ride Height
Unlike basic lowering spring and damper combinations, the TEIN Flex Z uses a full-length ride-height adjustment system.
Ride height is adjusted by changing the damper assembly length rather than relying solely on spring preload.
This helps maintain more consistent damper stroke while allowing you to select a practical ride height for your Honda Integra or Acura RSX.
TEIN’s UK catalogue lists a recommended lowering range of approximately 20–40mm for the Honda Integra DC5, with a wider mechanical adjustment range.
Always stay within the manufacturer’s recommended settings and check underbody, tyre and suspension clearances.
3. Twin-Tube Damper Construction
The Flex Z range uses twin-tube shock absorbers developed for comfortable and controlled road performance.
This arrangement is designed to provide smooth damping response and sufficient suspension travel on everyday roads.
It makes the kit suitable for owners who want a lowered stance and adjustable handling without using an uncompromising competition-only suspension system.
4. Performance Spring Rates for the DC5 Platform
TEIN specifies the following spring rates for VSA02-C1SA1:
- Front: 8 kgf/mm (approximately 448 lb/in)
- Rear: 10 kgf/mm (approximately 560 lb/in)
These springs form part of the complete kit and are matched to the suspension components.
The correct ride height, damping and alignment settings should be established together to achieve a balanced setup.
5. Front Camber-Adjustable Upper Mounts
The TEIN VSA02-C1SA1 includes camber-adjustable front upper mounts.
These allow adjustment of front wheel camber within the range permitted by the suspension and steering geometry.
Camber adjustment can be particularly useful after lowering a Honda Integra DC5, when suspension angles and tyre contact characteristics may change.
TEIN notes that available camber adjustment is limited by the vehicle’s characteristics. Toe must remain within a suitable adjustment range.
6. Corrosion-Resistant Construction
TEIN uses corrosion-resistant finishes and specialist coatings across the Flex Z range.
The distinctive green powder-coated components and protective damper treatments are designed to help protect the suspension against environmental exposure.
Correct cleaning and regular inspection are still recommended, especially during UK winter driving.
7. Compatible with TEIN EDFC Systems
The Flex Z range supports TEIN’s EDFC electronic damping adjustment technology on compatible applications.
An EDFC system can allow damping settings to be changed electronically using separately purchased control equipment and motors.
Additional installation requirements may apply to the Acura RSX DC5, including motor clearance modifications.
EDFC controllers and motors are not included with VSA02-C1SA1.
Honda Integra DC5 and Acura RSX Vehicle Compatibility
TEIN lists VSA02-C1SA1 for the Honda Integra DC5 Type R, selected Japanese-market Integra DC5 models and North American Acura RSX.
Relevant applications include:
- Honda Integra Type R DC5 – UK catalogue, 2002–2006
- Honda Integra Type R DC5 – Japanese-market models, 2001–2006
- Honda Integra Type S DC5 – selected Japanese-market models
- Acura RSX DC5 – North American models, 2002–2006
Although these vehicles share the DC5 platform, their specifications may differ by market, production date and original suspension components.
Confirm your exact vehicle before ordering.
Recommended Ride Height Settings
For Honda Integra DC5 applications, TEIN’s published recommended lowering range is approximately:
- Front: 20–40mm lower than standard
- Rear: 20–40mm lower than standard
Actual ride height depends on the vehicle variant, original specification, tyre size and adjustment.
Avoid choosing the lowest possible setting without checking available suspension travel, ground clearance and alignment.
TEIN Flex Z vs Standard Honda Integra Suspension
The original DC5 suspension was designed to deliver a balance of handling, stability and everyday performance.
The Flex Z introduces additional setup flexibility through adjustable ride height, damping control and front camber adjustment.
For a road-focused Integra Type R, this allows the owner to select a suspension configuration suited to their preferred balance of comfort, stance and steering response.
Correct alignment is essential to achieve good results and avoid premature tyre wear.

What Is Included in the TEIN VSA02-C1SA1 Kit?
The kit includes:
- Four TEIN Flex Z adjustable shock absorber assemblies
- Four matched suspension springs
- Front camber-adjustable upper mounts
- Vehicle-specific rear upper mounts
- Supplied adjustment accessories and fitting components
The suspension is supplied as a complete coilover system, rather than an individual replacement damper or spring set.
Installation and Wheel Alignment
Professional suspension installation is recommended.
Before fitting, inspect the condition of the steering joints, track rod ends, lower ball joints, driveshaft clearance, bushes and mounting points.
Important manufacturer note: TEIN identifies a left-hand-thread arrangement for the applicable front spring seat and locking components. Follow the supplied instructions carefully and do not force the components in the usual tightening direction.
After installation, set the ride height, check suspension travel and complete a four-wheel alignment.
