Best Suspension Kit for Ford Focus ST

Focus ST owners have two sensible routes: a coilover kit if you want to set the ride height, or a spring kit if you want to keep your standard dampers and spend less. The catch is that the ST is not a standard Focus, and plenty of Focus kits say so in the listing.

What to check before you buy

• Which ST you have. Mk2 ST225 (2005-2011), Mk3 ST250 (2012-2018, including the later 2.0 TDCi ST) and Mk4 ST (2019-on, 2.0 EcoBlue and 2.3 EcoBoost) all take different parts.
• Hatch or estate. Turnier and estate models are listed separately from hatchbacks, and spring rates differ.
• Read the exclusions. Kits that say "except ST models" will not fit your car, however cheap they look.
• Damping. Spring kits keep your existing dampers, so if they are past 60,000 miles, budget for replacements at the same time.
• What you actually want. Height adjustment for stance and corner weighting, or a modest, factory-quality drop.

Coilover options that include the ST

JOM BlueLine Focus 2, including ST 2.5, £184.96

Listed for Focus 2 1.6 Ti, 1.8, 2.0, TDCi and ST 2.5, 10.2004-2010, excluding Cabrio and Turnier. This is the correct kit for a Mk2 ST225 hatchback, and the cheapest height-adjustable option we stock for the ST.

JOM Redline Focus 2, including ST 2.5, £227.00

The Redline version of the same fitment, with JOM's stiffer fast-road setup.

Important: our JOM BlueLine Focus 3 kit at £194.38 is listed "except Turnier and ST models". It is a great kit for a standard Focus 3, but do not order it for an ST.

Spring kit options (Eibach), from £256.17

Eibach list ST-specific kits for every generation, which means correct spring rates rather than a compromise:

• Focus II 2.5 ST, 2005-2012 - £256.17
• Focus III 2.0 ST, 2011-2014 - £256.17 and 2012-on - £256.17
• Focus III 2.0 TDCi ST, 2014-on - £269.79
• Focus III Turnier 2.0 ST / 2.0 TDCi ST - £269.79
• Focus IV 2.0 ST EcoBlue / 2.3 ST EcoBoost - £262.13, and the estate version at £268.94

Fitment checklist for the Focus ST

1. Which generation and which ST, for example Mk2 ST225 or Mk3 2.0 TDCi ST.
2. Hatch or estate.
3. Read the listing for ST exclusions before ordering.
4. Damper mileage, if fitting springs only.
5. Wheel and tyre clearance at your intended ride height.

Fitting tips from our workshop

• Replace the front top mounts and bearings with the kit.
• If you are only fitting springs, inspect the dampers first. Worn dampers plus lowering springs is a bad combination.
• Book a four-wheel alignment afterwards.
• On an estate, check the rear arch clearance with the car loaded, not just empty.

FAQs

Coilovers or springs for a daily-driven ST? Springs, if your dampers are healthy and you want a modest drop. Coilovers, if you want to set ride height precisely or the dampers need replacing anyway.

Will lowering springs ruin the ST's handling? A quality kit with correct spring rates improves it. Cheap springs that drop the car too far make it worse.

Do I need to declare it to my insurer? Yes, any suspension change is a modification.
