Performance Upgrades
Mild to Wild. Supply & Install. Engine, Driveline & Suspension.
Whether you're chasing more horsepower, sharper handling, or a driveline that keeps pace with the rest of your build, Superformance can supply and install the right performance parts for your vehicle and your goals.
We work across the full scope of performance upgrades: complete turn key engines, forced induction, suspension systems, differential upgrades, transmission swaps, and brake conversions. We also supply and fit our own IFS kits engineered in-house to transform handling on classic vehicles still running stock beam-axle front ends.
Every upgrade is matched to your vehicle, your power level, and your intended use. We work on hot rods, street rods, muscle cars, classic American vehicles, Australian classics, and custom builds.
Driveline Packages
Engine, transmission & differential, with cooling and wiring to match.
A driveline upgrade is only as good as the systems around it. Superformance can supply and install complete driveline packages: engine, gearbox, and differential specified together, with cooling systems and wiring to suit. No mismatched components, no under-spec'd cooling on a big-block, no wiring bodged in after the fact.
From mild carb'd V8s to supercharged crate motors and LS swaps, we source and install the right combination for your build and we make sure the rest of the vehicle keeps up with it.
- Crate engine supply & installation
- LS & LT swaps
- Carburettor, EFI & forced induction setups
- Automatic & manual transmission swaps and upgrades
- Overdrive conversions for street-driven vehicles
- Torque converter selection & installation
- Exhaust, cooling & fuel system upgrades matched to power level
- Full custom wiring to suit
Suspension System Supply & Installation
IFS, IRS, coilovers, all set up correctly.
Factory suspension on most classic vehicles was built for a different era. It's soft, imprecise, designed around bias-ply tyres and drum brakes. It doesn't keep pace with a performance engine or modern tyres.
Superformance supplies and installs major suspension systems for classic vehicles. Every installation includes geometry setup and alignment. Suspension work that's bolted on without being properly set up doesn't perform. Corner weights, castor, camber, and toe are set before the vehicle leaves.
- IFS system supply & installation
- IRS system supply & installation
- Coilover conversion & setup
- 4-link rear suspension fabrication & installation
- Disc brake conversions front & rear
- Steering upgrades & rack conversions
- Chassis kits & strengthening supply & installation
- Wheel alignment & geometry setup
Superformance IFS Kits
Engineered in-house. Built for classic vehicles.
Our IFS kits are designed and engineered here at Superformance specifically for classic vehicles still running stock beam-axle front ends. A properly set-up IFS transforms how a classic vehicle drives: sharper steering response, better bump compliance, the ability to run modern radial tyres and disc brakes, and geometry that can actually be aligned.
Every kit is engineered to Australian standards and installed with full geometry setup included.
- Superformance IFS kits, engineered in-house
- Replaces beam-axle front ends on classic vehicles
- Modern steering geometry & disc brake capability
- Full alignment & geometry setup on installation
- Engineered to Australian standards
Differential Upgrades | Australian Made
A diff that handles your power and puts it to the ground properly.
Putting more power through a stock differential is a reliable way to break one. Superformance builds custom differentials in-house. From ratio selection and housing choice through to assembly, setup, and painting. Every diff is matched to your engine output, tyre combination, and intended use.
Our popular Ford 9-inch conversions, Posi and LSD installations, ratio changes, and custom housing builds - all done under one roof.
- In-house custom differential builds
- Ford 9-inch conversions & upgrades
- Ratio changes for street & strip
- Posi/LSD installations
- Diff housing repairs & modifications
- Matched to your power level & tyre combination
Supply & Install | Or Supply Only
Not every job needs our workshop. Some customers are doing their own installs. Some are interstate. Some just need the right part from the right supplier, not a second opinion on how to fit it.
Superformance can supply direct — performance parts, engines, transmissions, differentials, suspension systems, and more — drawing on direct USA import capability and supplier relationships built over four decades. If you can't find it in Australia, we can get it. If you need it fitted, we can do that too.
