Performance Upgrades & Track Preparation in Wimborne, Dorset

HLX Performance – BMW Specialist Workshop

Whether you’ve just bought a new performance car or you’re looking to take your existing setup to the next level, HLX Performance offers a comprehensive range of performance upgrades and track preparation services. From subtle improvements in braking and handling to full fast-road and track-focused builds, we can help you create a car that performs exactly how you want it to.

Our approach is simple: recommend the right upgrades in the right order, based on how you actually use your car. That might mean improving braking confidence on the road, sharpening handling for spirited driving, or preparing a reliable, repeatable setup for track days.

Brake Upgrades – Confidence, Control & Consistency

Brakes are the foundation of any performance or track build. More power is meaningless if the car can’t stop repeatedly and consistently. We offer brake upgrades ranging from simple improvements for fast-road use to full big brake kits for extreme performance and track abuse.

Upgraded Brake Pads (Fast Road & Track)

Performance brake pads are often the first and most cost-effective upgrade. They offer higher friction levels, improved heat resistance, and more consistent pedal feel compared to standard pads.

  • Improved bite and stopping power
  • Reduced fade under hard use
  • Fast-road, fast-road/track and full track compounds available

Pad choice is matched to your driving style to balance performance, noise, dust and disc wear.

Braided Brake Lines & Performance Brake Fluid

Braided brake lines replace the factory rubber hoses, reducing flex under pressure. This gives a firmer, more consistent pedal feel—especially when braking hard or repeatedly.

  • Sharper pedal response
  • Improved consistency during spirited driving or track use
  • Often paired with high-temperature brake fluid
Big Brake Kits (BBK)

For serious performance builds or regular track use, big brake kits offer a significant upgrade in stopping power, heat capacity and durability. Larger discs, multi-piston calipers and performance pads work together to manage heat far more effectively than standard systems.

  • Massively improved fade resistance
  • More consistent braking over long sessions
  • Improved pedal modulation and confidence

We can advise on the correct BBK size to suit your wheels, power level and intended use.

Suspension & Handling Upgrades

Suspension upgrades transform how a car feels. Whether you want a subtle improvement in body control or a fully adjustable setup for track geometry tuning, we can guide you through the options.

Lowering Springs

Lowering springs reduce ride height and improve aesthetics while lowering the car’s centre of gravity. They also reduce body roll and improve turn-in when paired with healthy dampers.

  • Improved stance and appearance
  • Sharper handling response
  • Best suited to fast-road builds
Adjustable Suspension Arms

Adjustable arms allow fine control over alignment settings such as camber and toe—essential for performance setups and track cars. They also help correct geometry after lowering.

  • Dial in aggressive alignment settings
  • Improve tyre contact and grip
  • Essential for track-focused geometry
Coilover Suspension Kits

Coilovers are the ultimate suspension upgrade, offering adjustable ride height and, depending on the kit, adjustable damping. This allows the car to be tuned for road comfort, fast-road performance or track use.

  • Full ride height adjustment
  • Improved body control and cornering stability
  • Wide range of options from road-biased to track-focused
Upgraded Anti-Roll Bars (ARBs)

Larger or adjustable anti-roll bars reduce body roll and help fine-tune balance between front and rear grip. They’re a highly effective upgrade when combined with suspension improvements.

  • Flatter cornering
  • Improved balance and steering response
  • Adjustable options available for fine tuning

Tyres – The Most Important Upgrade

Tyres are the only contact point between your car and the road or track. Choosing the right tyre can completely transform grip, braking performance and confidence.

Performance Road Tyres

Ideal for fast-road driving, these tyres offer excellent grip in both dry and wet conditions while maintaining reasonable comfort and longevity.

Track-Focused & Semi-Slick Tyres

Designed for maximum grip and consistency on track. These tyres offer incredible performance but require proper setup and temperature management.

We’ll advise on suitability for road use and alignment requirements.

Engine Performance Upgrades

Hardware upgrades allow your engine to breathe better, run cooler, and support higher power levels safely—especially when paired with ECU remapping.

Induction Kits

Performance induction kits improve airflow into the engine, reducing restriction and enhancing throttle response. Many also enhance intake sound for a more engaging driving experience.

Exhaust Systems & Sports Catalysts

Performance exhausts reduce back pressure, improve flow and enhance sound. Sports cats are often required to support Stage 2 ECU tuning by allowing higher exhaust flow while remaining road-usable.

  • Improved exhaust flow
  • Enhanced sound and character
  • Essential for Stage 2 power levels
Intercooler Upgrades

Upgraded intercoolers reduce intake air temperatures, especially under sustained load. This helps maintain consistent power, reduce heat soak and improve reliability on tuned or track-driven vehicles.

Track Preparation Packages

Track preparation isn’t about one single upgrade—it’s about balance and reliability. We can help you prepare your car properly with a combination of braking, suspension, cooling and safety-focused improvements.

  • Brake and fluid upgrades for sustained track use
  • Suspension setup and geometry optimisation
  • Performance tyres matched to alignment
  • Cooling and reliability checks before track days

Performance Upgrade Paths – Where to Start?

Not sure where to begin? Most performance builds follow a similar progression. Below are three common upgrade paths we recommend, depending on how you plan to use your car. These can be followed step-by-step or adapted to suit your goals, budget and driving style.

Fast Road Upgrade Path (Daily & Weekend Driving)

Ideal for drivers who want a sharper, more engaging car without sacrificing comfort or reliability. This path focuses on improving confidence, response and enjoyment on the road.

  • Performance brake pads – improved bite and confidence
  • Braided brake lines + performance fluid – firmer pedal feel
  • Performance road tyres – increased grip in all conditions
  • Lowering springs – improved stance and reduced body roll
  • Four wheel alignment – essential after suspension changes
  • Stage 1 ECU remap – stronger mid-range torque and drivability

This setup delivers a noticeable improvement without making the car harsh or impractical for everyday use.

Fast Road / Occasional Track Day Upgrade Path

Designed for drivers who enjoy spirited road driving and occasional track days. This path focuses on heat management, consistency and chassis control.

  • Fast-road/track brake pads – improved fade resistance
  • Braided brake lines + high-temp brake fluid
  • Upgraded anti-roll bars – flatter cornering and balance
  • Adjustable suspension arms – improved camber and tyre contact
  • Performance road or track-biased tyres
  • Coilover suspension kit – adjustable ride height and damping
  • Stage 1 or Stage 2 ECU remap (hardware dependent)
  • ZF/DSG TCU tune (auto) – recommended for higher torque

This setup gives you confidence on track while remaining usable on the road with the right component choices.

Full Track-Focused Upgrade Path

Built for regular track use and maximum performance. This path prioritises braking endurance, chassis precision, cooling and consistency over comfort.

  • Big Brake Kit (BBK) – maximum stopping power and heat capacity
  • Track-focused brake pads & fluid
  • Coilover suspension (track-oriented)
  • Adjustable suspension arms – aggressive geometry control
  • Upgraded anti-roll bars
  • Semi-slick or track tyres
  • Upgraded intercooler – reduced heat soak
  • Induction kit + exhaust + sports catalyst
  • Stage 2 ECU remap
  • ZF/DSG TCU tune (essential for autos)
  • Pre-track inspections & setup checks

Track builds are always about balance. We’ll advise on the correct order of upgrades to ensure reliability and repeatable performance.
