Tein Mono Sport Coilovers Honda NSX NA1 NA2 90-05

TEIN Mono Sport Coilovers for Honda NSX NA1 NA2 (1990-2005) – Mono-Tube Dampers, Full-Length Height Adjustment

TEIN Mono Sport replaces the original dampers and springs on your Honda NSX NA1 NA2 with a height-adjustable coilover kit, so you can set the stance you want and tighten up the handling without making the car uncomfortable. TEIN specifies 12 kgf/mm front and 14 kgf/mm rear spring rates for this application.

Mono Sport steps up to a mono-tube damper, where the oil and gas are kept apart so the oil can't foam under hard use. On strut cars TEIN uses its Upright Strong Tube design, which gives much of the side stiffness of an inverted strut without the extra sealing. Height is set by full-length adjustment and the 16-level adjuster uses TEIN's ADVANCE M.S.V. valve, which TEIN says gives a much wider spread between the softest and firmest settings.

The damper bodies get TEIN's two-layer powder coat, and the height-adjustment threads are protected by TEIN's low-friction ZTP coating, which resists rust and stone chips and helps stop the spring seats seizing. TEIN springs are cold-formed from SAE9254 spring steel and powder coated, and TEIN designs them to resist sagging over time.

Spring rates and ride heights are TEIN's application data. Heights are measured against the car's standard ride height and are a guide only: the result on your car depends on its condition, wheels and tyres, and load.

Key Features

• Mono-tube dampers with separate gas and oil chambers for consistent damping when hot
• Full-length height adjustment: ride height changes without shortening the stroke or altering preload
• 16-level damping adjuster with ADVANCE M.S.V. for a wide range from soft to firm (0 = stiffest, 16 = softest)
• Compatible with TEIN EDFC electronic damping controllers using motor kit EDK05-12120 (sold separately)
• Upright Strong Tube construction on strut applications for extra rigidity
• Vehicle-specific top mounts on most cars; pillow-ball front strut mounts allow camber adjustment
• TEIN SAE9254 springs matched to the car, powder coated and designed to resist sagging
• Suits fast road driving through to occasional track days

Installation

The kit replaces the complete original strut and damper assemblies. Set the ride height on the bench by screwing the damper body in or out of its lower bracket, then fine-tune on the car. TEIN pre-tightens the lower bracket lock rings only, so they must be fully tightened at fitting and checked regularly. Never shorten the body beyond TEIN's stated range. Tighten the top nut with a torque wrench while holding the piston rod on its flats; over-tightening can damage the adjuster. Leave suspension arm bolts loose until the car is back on its wheels, then torque them at normal ride height so the bushes aren't preloaded. TEIN advises lowering by no more than 30-40 mm to start with, keeping the front level with or 5-10 mm lower than the rear. Let the springs settle for a few days, recheck the height and lock rings, then have a full four-wheel alignment done. Fitting needs spring compressors (where strut assemblies are rebuilt), a torque wrench and a good understanding of the car's suspension. We recommend professional fitting.

Upgrade Further

Add a TEIN EDFC5 controller with motor kit EDK05-12120 to adjust damping from the driver's seat. Contact us for pricing.

Will this kit fit my Honda NSX NA1 NA2?

This kit (TEIN part GSH14-71SS1) is listed for the models in the Fitment section above. Check your chassis code, year and trim against that list, along with any notes under it. If you're unsure, send us your registration or VIN before ordering and we'll confirm.

How low will my Honda NSX NA1 NA2 go?

As supplied, TEIN's data puts the car approx. 30-45 mm lower than standard at the front and approx. 35 mm lower than standard at the rear. TEIN recommends staying within 20 to 55 mm below standard at the front and 25 to 45 mm below standard at the rear. Wheels, tyres and the car's condition all affect the final height.

Can I adjust the damping?

Yes. The 16-level adjuster changes compression and rebound together: 0 is the stiffest setting and 16 the softest. Start from TEIN's recommended setting and change it a few clicks at a time.

Does it work with TEIN EDFC?

Yes. You'll need TEIN's EDFC5 controller kit plus motor kit EDK05-12120 for this car, both sold separately. EDFC lets you change damping from inside the car.

Are top mounts included?

TEIN supplies vehicle-specific top mounts where the car needs them. On some models the original mounts are reused, so check them for wear before fitting.

Do I need a wheel alignment after fitting?

Yes. Changing ride height alters camber and toe, so have a full four-wheel alignment done once the springs have settled and the height is final.

Are TEIN coilovers road legal in the UK?

Coilovers can be used on UK roads as long as the car stays roadworthy: keep a sensible ride height, enough clearance and correctly aimed headlights. Modifying your suspension should be declared to your insurer.

Can Mono Sport dampers be serviced?

Yes. Mono-tube dampers like Mono Sport can be overhauled and revalved by TEIN. TEIN suggests a service every 2-3 years or 30,000-40,000 km on the road, or yearly with regular track use.

What warranty do TEIN coilovers come with?

TEIN UK covers its suspension for 12 months from the date of purchase against defects in materials and workmanship. Keep your invoice, as it's needed for any claim.
