Meet the ProSteed Subaru BRZ, our answer to everyone who's ever wondered what the FA24 platform could really do with proper development and quality components.
This car represents months of planning, testing, and learning what works when you push boundaries responsibly through thoughtful engineering and proven performance modifications.
We built this BRZ because we genuinely love the platform and wanted to explore its potential beyond factory limits without compromising reliability or daily usability—especially at WTAC 2025!
The world-first FA24 Nitto conrods, TurboSmart 6464 turbo, and supporting modifications represent our commitment to proving that thoughtful engineering can unlock serious performance potential. Every component was selected through research and testing, creating a cohesive build that performs consistently whether you're daily driving or chasing lap times.
Engine: Where the Magic Happens
The heart of this build is the FA24 engine that's been completely reimagined with a focus on maximum performance.
Core Engine Components:
• CP Pistons - Forged internals that laugh at boost pressure
• World-First FA24 Nitto Conrods - Because being first means dealing with everyone else's "learning experiences"
• TurboSmart 6464 Turbo - Enough airflow to pressurise a small building
The FA24 platform was begging for this kind of treatment. Stock internals are fine if your idea of excitement is merging onto the highway, but when you want real power, you need components that won't surrender at the first sign of serious boost. These Nitto conrods are literally the first of their kind for this engine.
Built and tuned by Pulse Racing, because when you're pushing boundaries, you want people who know where those boundaries are and exactly how far past them you can go before things get expensive.
Cooling: Keeping Things Chill When Everything's on Fire
Heat is the enemy of horsepower, and the enemy of keeping your engine in one piece. The cooling system isn't an afterthought here.
Cooling Solutions:
• CSF Radiator - Bar and plate construction that actually works when track temperatures climb
• Upgraded cooling fans - Because airflow matters when you're sitting in traffic after destroying lap records
• Proper ducting and airflow management - Every CFM counts when things get spicy
The stock cooling system works great if you never push the car harder than a Sunday drive to the shops. Add serious power and track time, and suddenly you're learning expensive lessons about heat management. The CSF radiator handles the thermal load that would leave stock cooling systems waving white flags.
Fuel System: Keeping the Party Going When Physics Gets Involved
More power needs more fuel, delivered consistently, even when cornering forces are trying to slosh everything around like a washing machine full of gasoline.
Fuel Delivery Components:
• Radium Engineering Surge Tank - Prevents fuel starvation when lateral loads get serious
• Injector Dynamics 1750cc Injectors - Flow capacity for current power and future power desires
• Zeitronix Ethanol Flex Fuel Kit - E85 capability because corn fuel makes everything better
Fuel starvation is the kind of problem that sneaks up on you during the best part of a track session. One minute you're setting personal bests, the next you're learning why consistent fuel pressure matters. The Radium surge tank solves this before it becomes a problem, because preventing issues is cheaper than fixing them.
Suspension: Making Physics Work for You Instead of Against You
The AST coilovers aren't just springs with fancy adjusters. This is precision engineering that understands what suspension is supposed to do beyond just lowering the car.
Suspension Setup:
• AST 3-Way Adjustable Coilovers - Compression, rebound, and ride height adjustments that actually work
• Complete HardRace Control Arm Catalog - Every bushing and joint replaced with components that maintain geometry
• HardRace Strut Bracing - Chassis rigidity that keeps everything pointed in the right direction
Stock suspension works fine for commuting and grocery runs. Add track time and serious cornering loads, and suddenly you're discovering why proper suspension geometry matters. The AST setup maintains control through corners that would leave stock suspension crying for help.
Braking: Stopping Power That Matches the Going Power
Big power needs big brakes, especially when you're converting kinetic energy back to heat on a regular basis.
Braking Components:
• Alcon TA6 Front Big Brake Kit - Six-piston calipers because four apparently wasn't enough
• Alcon TA4 Rear Big Brake Kit - Balanced braking that works lap after lap
• Dixcel FS Type Rotors - Heat dissipation that prevents the dreaded brake fade
• Dixcel RA Pads - Consistent friction when temperatures climb
Stock brakes work great for the first few corners of a track session. After that, you're experiencing what brake fade feels like firsthand. The Alcon setup provides consistent stopping power that doesn't deteriorate when things get hot, which is exactly when you need brakes to work most.
Aero: Because Physics Applies to Everyone
The Voltex aero package isn't just for looks, though it definitely doesn't hurt that it makes the car look like it means business.
Aerodynamic Components:
• Voltex Complete Body Kit - Functional aero that actually manages airflow
• Voltex Rear Wing - Downforce where it counts most
• Voltex Front Splitter - Balanced aerodynamics that work together
Aero only matters at speed, but when it matters, it really matters. The Voltex pieces work together to manage airflow and generate downforce that helps plant the car when cornering speeds climb beyond what suspension alone can handle.
Interior: The Business Office Where Lap Times Happen
The interior focuses on function over fancy trim pieces, because weight reduction and proper ergonomics matter more than cup holders.
Interior Modifications:
• Tillet C1 Racing Seat - Proper lateral support that keeps you connected to the car
• AEM 5" Dash - All the data you need, none of the distractions you don't
• Zestek CAN Controller - Electronics management that actually makes sense
The stock seats are comfortable for road trips but useless when cornering forces start building. The Tillet seat keeps you exactly where you need to be for consistent inputs, while the AEM dash provides real-time data that helps you understand what the car is doing.
Exhaust: Making the Right Noises for the Right Reasons
The Invidia titanium exhaust system handles exhaust gas flow while making sounds that remind everyone within a three-block radius that this isn't your average BRZ.
Exhaust System:
• Invidia Titanium Exhaust - Proper flow characteristics with weight savings
• Optimal exhaust gas velocity - Engineering that improves performance, not just sound
• Titanium construction - Because weight matters and titanium sounds expensive
A proper exhaust system does more than make noise. The Invidia system improves exhaust gas flow, reduces weight, and yes, makes the kind of sounds that let people know you're serious about this whole performance thing.
WTAC 2025: Where We Put Our Money Where Our Mouths Are
The World Time Attack Championship at Sydney Motorsport Park on September 5-6 is where this build gets its real test. Not a dyno session, not a magazine photo shoot, but actual track time against actual competition where actual lap times matter.
WTAC is the ultimate proving ground for performance parts. When teams roll up with six-figure builds and months of preparation, they're not running parts from the clearance bin. They're running components that work when everything's on the line, which is exactly why our parts list reads like a greatest hits album of proven performers.
This is our chance to prove that the ProSteed BRZ isn't just a collection of parts bolted together. It's a cohesive build where every component works with every other component to create something that's greater than the sum of its parts.
The Bottom Line: Built Right, Driven Hard
The ProSteed BRZ represents everything we believe about building performance cars the right way. No shortcuts, no compromises, no "good enough for now" components that you'll just have to replace later anyway.
Every part on this car was chosen because it works, tested because it matters, and installed because we believe in doing things properly the first time. Whether you're building for weekend track days or chasing lap records, the same principles apply: buy once, cry once, then enjoy the results for years to come.
This isn't just our show car. It's our proof of concept that performance parts should work as hard as the people who install them.
