Lowering Springs vs Full Suspension Kits – What’s Best for Your Ford ST or RS?

Lowering Springs vs Full Suspension Kits – What’s Best for Your Ford ST or RS?

Whether you own a Fiesta ST, Focus ST, Focus RS or another fast Ford, lowering your car is often one of the first modifications you’ll consider. A lower stance improves the appearance, reduces body roll and can sharpen handling—but how you achieve it makes a huge difference.

Many owners choose lowering springs because they’re affordable, while others opt for a complete suspension upgrade with matched springs and dampers. So which is right for your Ford?

Let’s break it down.


Option 1: Lowering Springs

Lowering springs replace only the factory springs while keeping your original shock absorbers (dampers).

Typically lowering the car between 20mm and 40mm, they’re a cost-effective way to improve the look of your Ford.

Pros

✔ Affordable upgrade

✔ Improved appearance

✔ Lower centre of gravity

✔ Reduced body roll

✔ Can improve cornering over standard suspension

Cons

✖ Original dampers weren’t designed for shorter springs

✖ Ride quality can become harsher

✖ Dampers wear out more quickly

✖ Can become bouncy over uneven roads

✖ Performance isn’t fully optimised

Think of it like wearing running shoes that are two sizes too small—they’ll work, but they aren’t designed for the job.


Option 2: New Springs and Dampers

A matched suspension kit replaces both the springs and the dampers, ensuring they’re engineered to work together.

Brands like Bilstein, Eibach and other quality suspension manufacturers spend countless hours testing spring rates alongside damper valving, creating a setup that balances comfort with performance.

Pros

✔ Better handling

✔ Improved ride quality

✔ Reduced bouncing

✔ Longer lifespan

✔ Better control over rough roads

✔ More confidence when driving quickly

✔ Less strain on suspension components

Because the dampers are designed for the shorter springs, the suspension remains controlled throughout its travel.


Why Do Standard Dampers Wear Out?

This is probably the biggest misconception in the modification world.

Factory dampers are designed to operate within a certain section of their travel.

When lowering springs are fitted:

  • The damper sits further into its stroke.
  • It has less suspension travel available.
  • It works harder over every bump.
  • Internal seals and valves experience increased stress.

The result?

Premature damper wear.

Many people fit lowering springs, only to replace the original dampers 12–24 months later anyway.


Ride Comfort

One of the biggest surprises for owners upgrading to a quality spring and damper kit is that the car often rides better than it did on lowering springs alone.

That sounds backwards…

…but it makes sense.

A properly matched suspension setup controls the movement of the spring.

Instead of constantly bouncing after hitting a pothole or speed bump, the damper absorbs the energy and settles the car almost immediately.

The result is a ride that’s firmer, but far more controlled and comfortable.

What About Coilovers?

If you’re chasing maximum performance or want adjustable ride height, coilovers are another option.

They allow you to fine-tune the height of your Ford and, on many kits, adjust damping too.

However, unless you genuinely need adjustability for track use or show cars, a quality matched spring and damper kit often provides the best balance of comfort, handling and value for everyday road driving.


Which Should You Choose?

Choose lowering springs if:

  • You’re on a tighter budget.
  • Your factory dampers are still in excellent condition.
  • You’re mainly looking for improved aesthetics.

Choose a full suspension kit if:

  • You enjoy spirited driving.
  • You want the best ride quality.
  • Your original dampers have covered high mileage.
  • You plan to keep the car for years.
  • You want handling improvements as well as looks.


Our Recommendation

If your Ford has already covered 50,000–70,000 miles, fitting lowering springs alone can be a false economy. The original dampers may already be showing signs of wear, and adding shorter springs only increases the workload.

A matched spring and damper kit costs more initially, but delivers a better ride, sharper handling and longer-lasting performance. For many ST and RS owners, it’s the upgrade they wish they’d done first.

At Retro Fast Fords, we stock suspension upgrades for a wide range of Ford ST and RS models, from simple lowering springs to complete suspension packages from trusted performance brands. Whether you’re building a daily driver, weekend toy or track-focused project, choosing the right setup will transform the way your Ford looks and drives.
