Tein Mono Racing Coilovers Mitsubishi Lancer Evolution X CZ4A 07-16

TEIN Mono Racing Coilovers for Mitsubishi Lancer Evolution X CZ4A (2007-2016) – Track-Focused Mono-Tube, Camber Adjustable Mounts

TEIN Mono Racing is a motorsport-derived coilover kit for the Mitsubishi Lancer Evolution X CZ4A, giving you adjustable ride height and damping to set the car up properly for track days and competition. TEIN specifies 16 kgf/mm front and 14 kgf/mm rear spring rates for this application (other rates can be chosen when ordering).

Mono Racing is TEIN's coilover for drivers who regularly do track days. It uses mono-tube dampers with TEIN's ADVANCE M.S.V. valve, full-length height adjustment and, on most strut cars, pillow-ball top mounts derived from TEIN's Super Racing kit with independent camber and caster adjustment. Springs are matched to the car, and TEIN lets you choose different spring rates when ordering.

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 on track
• Full-length height adjustment for setting ride height and corner weights without changing stroke
• 16-level damping adjuster with ADVANCE M.S.V. (0 = stiffest, 16 = softest)
• Compatible with TEIN EDFC electronic damping controllers using motor kit EDK05-12140 (sold separately)
• Pillow-ball top mounts with camber adjustment, plus caster adjustment on many strut cars
• Upright Strong Tube construction on strut applications for extra rigidity
• Spring rates can be chosen when ordering on many cars
• Can be overhauled and revalved by TEIN

What's in the Kit?

• 4 x Mono Racing height-adjustable dampers
• 4 x TEIN coil springs (rates as listed below or as chosen when ordering)
• Pillow-ball top mounts (vehicle-specific)
• Ride-height adjusting spanner
• Fitting instructions

Kit notes from TEIN:

• Optional camber washers SPS12-R16100-25 move camber further positive and SPS12-R16100-05 further negative (both sold separately).
• Front spring rate chosen from 14, 16 or 18 kgf/mm and rear from 14 or 16 kgf/mm when ordering.
• Special order only in the UK: springs must be chosen when ordering.

Fitment

• Mitsubishi Lancer Evolution X CZ4A (Oct 2007 to Mar 2015), GSR, RS, 2.0L AWD

Not suitable for: other Mitsubishi Lancer Evolution X generations, body styles or drivetrains not listed above, as they use different TEIN part numbers. If your exact model isn't listed, contact us with your registration before ordering.

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.

Vehicle-specific notes from TEIN:

• Camber is set with eccentric washers; four per car are required.

Upgrade Further

Lowering changes the anti-roll bar geometry. TEIN's adjustable drop links let you correct it: Tein Rear Adjustable Drop Links Mitsubishi Lancer Evolution X CZ4A. Add a TEIN EDFC5 controller with motor kit EDK05-12140 to adjust damping from the driver's seat. Contact us for pricing.

Will this kit fit my Mitsubishi Lancer Evolution X CZ4A?

This kit (TEIN part VSE18-K1LS4) 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 Mitsubishi Lancer Evolution X CZ4A go?

As supplied, TEIN's data puts the car approx. 50-55 mm lower than standard at the front and approx. 30-40 mm lower than standard at the rear. TEIN recommends staying within 40 to 65 mm below standard at the front and 20 to 50 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 EDK05-12140 for this car, both sold separately. EDFC lets you change damping from inside the car.

Are top mounts included?

Yes. Pillow-ball top mounts are included. They give sharper steering feel and camber adjustment, but can transmit a little more noise than rubber mounts.

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.

Is Mono Racing too stiff for the road?

Mono Racing is aimed at regular track use, so it's firmer than Flex Z or Mono Sport, but the 16-level adjuster gives a usable range. If the car is mainly used on the road, Mono Sport is usually the better choice.

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.
