Ford Fiesta ST Tuning: Schropp’s Lightweight Last Edition Upgrade

Lightweight Wheels: Barracuda Summa Ultralight

One of the most effective upgrades is the wheel package. Schropp fitted the Last Edition ST with Barracuda Racing Wheels — the Summa design from the Ultralight Series.

Flow-forming production gives these wheels high strength with reduced mass, which directly improves steering feel and unsprung weight behaviour.

In the featured setup, the car runs 7.5x18-inch bronze Summa wheels wrapped in 205/40 ZR18 Michelin Pilot Sport 4 tyres.

Each 18-inch wheel weighs roughly 8.4 kg, trimming rotating mass and sharpening response. For drivers who want the absolute lightest setup, Barracuda offers a 7.5x17-inch Summa at about 7.2 kg per wheel.

Chassis Work: Eibach Lowering Springs

Wheels need matching suspension tweaks to work properly. Schropp installed Eibach lowering springs to reduce ride height, flatten body roll and quicken turn-in.

Lowering springs are a simple, affordable mod that improves stance and real-world handling when paired with correct alignment.

The combination of lighter wheels and a lower centre of gravity helps the Fiesta feel more planted through tight corners.

It's not an extreme track setup; Schropp aimed for everyday usability with a more focused feel on back roads and B-roads where the ST traditionally shines.

Power Upgrade: ECU Tuning for a Stronger Punch

Under the bonnet, the familiar 1.5-litre three-cylinder turbo receives an ECU remap. Standard output of 200 hp and 320 Nm rises to approximately 230 hp and 370 Nm.

That increase broadens the usable torque band and gives the hatch a crisper mid-range surge.

The tune keeps the engine's character — lightweight, rev-happy and eager — while delivering noticeably quicker acceleration and stronger in-gear performance.

The extra torque complements the chassis upgrades, making the Fiesta more confident when exiting corners.

Driving Impressions: What Changes on the Road

On twisty roads, the upgrades are easy to feel. Reduced unsprung weight tightens turn-in and improves feedback through the steering wheel.

Lowered springs reduce pitch and roll, letting you carry speed more confidently into bends.

The added power changes the personality subtly: the ST now accelerates with more authority out of mid-corner, which makes the package feel faster without losing the nimble, grin-inducing character that made the Fiesta ST famous.

Why This Matters — And What Comes Next

The Last Edition Fiesta ST is more than a tuned car; it's a statement.

As mainstream manufacturers shift model lineups and electrify, well-executed tuning keeps analogue driving thrills alive. Simple, weight-focused changes deliver big returns for driver engagement.

Looking ahead, expect more tuners to prioritise weight saving, better tyres, and modest ECU work over heavy hardware swaps.

For owners who want a usable, sharper Fiesta without losing daily practicality, Schropp's recipe is both sensible and potent.
