Tein RX1 Coilovers Lexus CT200h ZWA10 ZWA10L 11-22

TEIN RX1 Coilovers for Lexus CT200h ZWA10 ZWA10L (2011-2022) – Made for MPVs, 16-Way Damping

TEIN RX1 lowers your Lexus CT200h ZWA10 ZWA10L while keeping it comfortable for passengers, replacing the original dampers and springs with a height-adjustable kit designed for MPVs. TEIN specifies 4 kgf/mm front and 5 kgf/mm rear spring rates for this application.

RX1 is TEIN's coilover for minivans and MPVs, where comfort for passengers matters as much as a lower stance. It uses twin-tube dampers with full-length height adjustment, a 16-level adjuster and TEIN's Hydraulic Bump Stopper (H.B.S.), which cushions the end of the stroke when the car is lowered and fully loaded.

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.

Specifications

• Damper type: Twin-tube, gas and oil, with H.B.S.
• Height adjustment: Full-length (case-length) adjustable

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

• Designed for minivans and MPVs: lowered stance with passenger comfort in mind
• Full-length height adjustment: ride height changes without shortening the stroke
• 16-level damping adjuster (0 = stiffest, 16 = softest)
• Compatible with TEIN EDFC electronic damping controllers using motor kit EDK05-12120 (sold separately)
• Hydraulic Bump Stopper (H.B.S.) softens full-compression hits when loaded
• Vehicle-specific top mounts included
• TEIN SAE9254 springs matched to the car, powder coated and designed to resist sagging

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

Lowering changes the anti-roll bar geometry. TEIN's adjustable drop links let you correct it: Tein Front Adjustable Drop Links Lexus CT200H ZWA10, Tein Front Adjustable Drop Links Lexus CT200H ZWA10L. 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 Lexus CT200h ZWA10 ZWA10L?

This kit (TEIN part VSQ36-M1AS3) 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 Lexus CT200h ZWA10 ZWA10L go?

As supplied, TEIN's data puts the car approx. 35 mm lower than standard at the front and approx. 30 mm lower than standard at the rear. TEIN recommends staying within 25 to 45 mm below standard at the front and 20 to 40 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?

Yes. Vehicle-specific top mounts are included in the kit.

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.

Will RX1 still be comfortable with a full car?

That's what RX1 is designed for. The twin-tube dampers are tuned for comfort and the Hydraulic Bump Stopper cushions the end of the stroke when the car is lowered and carrying passengers.

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.
