In the performance automotive world, having access to the right components can make all the difference.
For workshops, engine builders, performance retailers and race teams, the challenge isn’t simply finding quality parts. It’s finding a reliable supplier, maintaining healthy margins and being able to give customers access to components that are designed for serious performance.
That is where the STK Performance Authorized Stockist Programme comes in.
STK Performance specializes in high-performance cylinder head components, including racing camshafts, valve spring kits, forged valves, retainers, lifters and other valvetrain components. The company supplies performance-focused customers in South Africa and internationally, with products aimed at everything from modified street cars to dedicated competition engines.
For businesses operating in the automotive performance industry, becoming an authorized STK stockist provides an opportunity to add an established performance brand to your product offering while accessing dedicated trade pricing.
More Than Just Another Parts Supplier
A performance parts business is built on trust.
Customers don’t want to buy a camshaft, valve spring kit or forged valve simply because it looks good on a product page. They want to know that the component is appropriate for their engine, that it will perform as expected and that the person supplying it understands what they’re selling.
STK Performance has built its range around the cylinder head and valvetrain — some of the most important areas of a performance engine.
Its current product range includes racing camshafts, valve spring kits, forged valves, valve spring retainers, lifters and cam buckets, as well as complete performance combinations for a range of popular applications.
That gives workshops and retailers the opportunity to offer customers more than a single upgrade. Instead, they can build a broader performance solution around the engine’s requirements.
And that’s particularly important when customers start pushing an engine beyond its original factory specifications.
Why the Valvetrain Matters
When enthusiasts talk about performance upgrades, the conversation often jumps straight to turbochargers, exhaust systems, injectors and ECU tuning.
But inside the cylinder head, the valvetrain is working incredibly hard.
The camshaft controls when the engine’s valves open and close, while the valve springs, retainers, valves and lifters help ensure those movements remain controlled as engine speed increases.
As RPM rises and cam profiles become more aggressive, the demands placed on these components increase dramatically.
A performance camshaft therefore shouldn’t necessarily be viewed as an isolated modification. It needs to work as part of a complete system.
STK itself emphasizes the importance of supporting components when upgrading a performance camshaft, particularly where higher RPM operation and more demanding engine configurations are involved.
For a workshop or engine builder, this creates an opportunity: instead of simply selling one component, you can help customers build a properly matched valvetrain package.
Who Is the STK Authorized Stockist Programme For?
The programme is specifically aimed at registered businesses operating within the automotive trade.
STK identifies three key groups that can benefit from the programme:
Performance Workshops
Tuning shops and engine builders regularly installing camshafts, valves and valve springs can benefit from having direct access to STK’s range at trade pricing.
For these businesses, the programme can make it easier to source components for customer builds while improving the commercial side of each project.
Whether you’re rebuilding a naturally aspirated engine, developing a turbocharged street car or preparing a dedicated race engine, having a dependable performance-component supplier is an important part of the process.
Parts Retailers
Automotive parts retailers — both physical and online — can also apply.
STK’s range covers applications across popular performance platforms, including Volkswagen, Audi, BMW, Ford and Toyota, among others. The website currently lists more than 100 products across its catalogue, with applications ranging from individual components to complete performance kits.
For retailers, this means the opportunity isn’t limited to selling one type of engine component.
You can potentially build an STK section within your existing performance parts business and offer customers access to products covering multiple applications.
Race Teams & Competition Specialists
Motorsport places demands on components that ordinary road use simply doesn’t replicate.
High RPM, sustained engine loads and aggressive performance specifications can expose weaknesses very quickly.
STK’s involvement in motorsport is therefore an important part of the brand’s identity. The company describes racing as part of its heritage and highlights its involvement in the Super Turismos Light 1.8V Mexican Series, wide range of formulas in South Africa (Single Seaters, Rally, Oval Track and Drags) where its components are exposed to demanding competition conditions.
For race teams and engine builders, that motorsport connection can provide an additional layer of confidence when selecting components for serious builds.
No Chasing Quotes Every Time You Order
Another advantage is the simplicity of the ordering process.
Once an application has been approved and the stockist account has been created, the trade discount is automatically applied in the cart whenever the account holder is logged in.
That means the normal retail price can remain visible while browsing, with the applicable trade discount appearing at checkout.
For a busy workshop or retailer, that matters.
Instead of repeatedly emailing for prices, waiting for quotes or manually calculating discounts, the system handles the calculation automatically.
The best part? Courier and VAT is already sorted from our side.
Less administration means more time spent building engines, serving customers and growing the business.
What Does the Application Process Look Like?
Becoming an authorized stockist isn’t simply a case of creating an account and immediately receiving wholesale pricing.
STK reviews applications to establish whether the applicant is an appropriate automotive-trade business.
The process is straightforward:
1. Apply
Complete the authorized stockist application with your company and trading information.
2. STK Reviews Your Application
The STK team reviews the information provided and may contact you if additional details are required.
3. Your Account Is Created
Once approved, you’ll receive an email containing a link to set your password and access your account.
4. Start Ordering
After logging in, your applicable trade pricing is automatically calculated in the shopping cart.
The application requests information such as company details, registration information, contact details, website and social media profiles, years in business, business type, brands currently sold and estimated monthly purchases.
This helps STK understand the type of business applying and its potential requirements.
A Brand Built Around Performance
One of the interesting aspects of STK Performance is that the company isn’t positioned as a general automotive parts supplier.
Its focus is much narrower — and that’s a strength.
STK specializes in cylinder head components and performance valvetrain technology.
The company was founded in 2003 by Simon Johnstone, whose career includes experience with VW Motorsport and Audi Sport South Africa, as well as extensive experience in high-performance engine development and parts management. STK now operates with locations in South Africa, the United Kingdom and Mexico City.
That background gives the brand a strong connection to the performance-engineering world rather than simply the aftermarket parts market.
From Street Cars to Serious Competition
Performance engines come in many forms.
One customer might want a sharper camshaft for a weekend street car.
Another could be building a naturally aspirated engine designed to operate at extremely high RPM.
Another might be developing a turbocharged engine where the factory valvetrain is no longer suitable for the intended power and RPM range.
STK’s catalogue is designed to cover many of these applications.
Current products include components for platforms such as VW 8V and 16V engines, Audi 1.8T and 20V applications, BMW engines, Toyota applications, Nissan SR20 engines and Opel platforms, among others.
The range also includes complete kits combining components such as valve springs, retainers and valves — useful for builders who want a more comprehensive solution rather than sourcing every component separately.
Real-World Performance Matters
Perhaps the most important question for any performance component is simple:
Can it survive the job it’s being asked to do?
STK has highlighted real-world examples of its components being used in demanding builds.
One example is a Datsun A15 racing engine belonging to racer Dillon Kruger. The naturally aspirated engine uses STK performance valve springs and is currently being operated at competition RPMs approaching 9,800 rpm.
That kind of application demonstrates why valvetrain components matter so much in high-RPM engines.
At those engine speeds, maintaining accurate valve control isn’t a minor detail — it is fundamental to keeping the engine operating reliably.
Why This Matters for Your Customers
Becoming a stockist isn’t only about getting cheaper parts.
It’s about improving what you can offer your customers.
Imagine a customer walks into your workshop wanting to build a higher-revving VW, upgrade an Audi 1.8T, improve the valvetrain in a BMW or prepare a Toyota engine for competition.
Instead of simply telling them to source their own components, you can potentially supply the parts yourself.
That creates another revenue opportunity while also allowing you to become a more complete solution provider.
For online retailers, the same principle applies.
Adding a recognized performance brand to your catalogue can help expand your product selection and give enthusiasts another reason to shop through your store.
The Opportunity for Growing Performance Businesses
For smaller automotive businesses, gaining access to established performance brands can be difficult.
Margins matter. Stock availability matters. Supplier relationships matter. And so does having products that customers actually want.
The STK Authorized Stockist Programme is designed around those realities.
With trade pricing across the STK range, automatic discounts at checkout and higher discount tiers for larger orders, the programme provides a straightforward way for eligible businesses to purchase STK products for resale or use in their own builds.
The structure also allows businesses to start at a lower order level and potentially move into better pricing as their purchasing volume increases.
Is Becoming an STK Stockist Right for Your Business?
If you’re a registered automotive business and your customers are interested in performance engines, the answer may be worth exploring.
The programme is particularly relevant if you:
- Build or modify performance engines
- Install performance camshafts
- Upgrade valve springs and valvetrains
- Prepare race or competition engines
- Sell aftermarket performance components
- Operate an online performance-parts store
- Regularly purchase components for customer builds
- Want to expand your performance product range
- Are looking for improved trade margins
STK’s current programme is specifically intended for businesses within the automotive trade rather than ordinary retail customers.
Performance Starts With the Right Components
A fast engine isn’t built from one part.
It’s the combination of the camshaft, cylinder head, valves, springs, retainers, lifters, fueling, ignition, exhaust and tuning that ultimately determines how the engine performs.
For businesses working on those builds every day, having access to the right components — and the right supplier — can make the entire process easier.
STK Performance has built its business around those critical cylinder-head and valvetrain components, combining performance-focused products with a stockist programme designed specifically for workshops, retailers, engine builders and race teams.
If your business is already working in the performance automotive market, becoming an STK Authorized Stockist could be an opportunity to add a proven performance brand to your offering while accessing dedicated trade pricing.
