Performance Upgrades

Enhancing the Drive — On the Road, Track, or Stage.

At Speedshop44, we specialise in high-quality performance upgrades for modern and future classic vehicles from the 1980s, to early 2010s. Whether you're building a fast road car, prepping for track days, or competing in motorsport, we provide expert enhancement solutions that deliver results you can feel. 

From iconic legends like the Audi Quattro, Subaru Impreza, and Fast Fords, to precision machines like the Honda Civic Type R, Porsche 911, and classic Ferrari, our upgrade services are designed to enhance performance, handling, and reliability—without compromising the character of your vehicle.

Upgrade Services Include:

Brake System Enhancements

We offer full brake system upgrades tailored to your driving needs, from high-friction performance pads and slotted discs for fast road use, to big brake kits and braided lines for serious track and motorsport applications. Improved stopping power, reduced fade, and sharper pedal feel make your modern classic safer and more responsive under pressure.  

Suspension Tuning & Geometry Setup

Upgrade your handling with adjustable coilovers, polyurethane bushes, anti-roll bars, and chassis bracing. We offer custom suspension setups, including track-specific geometry alignment, camber/caster adjustments, and corner weighting, giving you improved grip, balance, and confidence.

Exhaust System Upgrades

Enhance both power and soundtrack with mandrel-bent stainless systems, performance manifolds, and sports catalysts or de-cat options. Our exhaust upgrades reduce back pressure and improve engine breathing for sharper throttle response and increased horsepower - dyno-tested for real-world gains.

Wheels & Tyres

Choose from a range of lightweight alloy wheels that reduce un-sprung weight and improve responsiveness. Pair them with high-performance tyres specifically suited to your driving style—whether it's road-biased comfort or track-ready grip—for a complete handling transformation.

ECU Tuning & Custom Remapping

Using our in-house rolling road dyno, we develop custom ECU maps for both standard and modified engines. We fine-tune fuel delivery, ignition timing, turbo boost, and other critical parameters to extract maximum power, drivability, and efficiency - all based on live, load-tested data, not guesswork.

Intake & Induction Upgrades

Improve engine breathing with high-flow air filters, cold air intakes, and performance inlet manifolds. When combined with ECU tuning, these upgrades help your engine run more efficiently and produce noticeable performance gains across the rev range.

Cooling System Improvements

For vehicles seeing spirited use or track time, we offer uprated radiators, oil coolers, intercoolers, and improved ducting to keep temperatures in check, ensuring your engine performs reliably under pressure. 

Drivetrain & Transmission Enhancements

We supply and install uprated clutches, lightweight flywheels, limited-slip differentials (LSDs), and short-shift kits to help put your newfound power down more effectively. Ideal for fast road and motorsport builds where control and durability are key.

Wiring and Electronics

CAN bus systems have become especially important in modern and future classics where advanced electronics and diagnostics play a crucial role in performance and functionality.

As CAN bus specialists, we offer expert installation of electronic components including digital dashboards, switch panels, and external water pump conversions. Whether you need a full or partial custom wiring loom, we’ll tailor it precisely to suit your new ECU setup ensuring flawless communication, reliability, and integration across your modern classic build.

Dyno-Proven Results

All engine and ECU tuning is carried out using our advanced rolling road dynamometer, allowing us to simulate real-world driving conditions while accurately measuring horsepower, torque, and engine response. This ensures that every upgrade is backed by data and fine-tuned to deliver the performance gains you expect.
