Built from Hoosier’s Racing Heritage

The TrackAttack Pro was developed using Hoosier’s proprietary H-DNA technology, incorporating over 65 years of racing experience into a tire designed for both street and track use. Unlike traditional street tires that prioritize comfort above all else, the TrackAttack Pro was engineered for drivers who want motorsport-level performance every time they get behind the wheel.

Built for Serious Competition

The Hoosier R7 was developed for dedicated racing applications where ultimate performance is the priority. Unlike traditional high-performance street tires, the R7 is engineered specifically for racetrack use, delivering significantly higher levels of grip, responsiveness, and cornering capability. The tire is commonly used in:

The Hidden Cost of Poor-Quality Exhaust Components

A badly built exhaust system rarely fails immediately. Problems usually appear over time through:

What Does a Camshaft Actually Do?

The camshaft controls:

• Valve opening timing
• Valve closing timing
• Valve lift
• Valve overlap

These factors directly affect:

The Beginning of GT40 Developments

The story began when John Botha was gifted an original spare GT40 body that belonged to a GT40 campaigned and raced in South Africa. Having spent several years working extensively on GT40 chassis P/1024, Botha possessed an intimate understanding of the car's engineering and construction.

Fatigue Fracture

Fatigue fracture is the most common valve spring failure mode. A spring cycling at 7,000 RPM opens and closes each valve 3,500 times per minute — that is 210,000 stress cycles per hour. Over time, micro-cracks initiate and propagate until the wire breaks.

Based in Mbombela, Mpumalanga, Mountings & Bushes is a proudly South African, family-owned company specialising in the design, manufacture, and refurbishment of polyurethane bushes, mountings, and related suspension components for a wide range of vehicles and applications.

What Is a Straight Pipe?

A straight pipe is a free-flowing section of exhaust tubing designed to maximise airflow and simplify exhaust routing.

It’s commonly used for:

The Problem: Valve Float in High-Performance Engines

One of the biggest problems in modified engines is valve float.

Valve float happens when the valve spring cannot close the valve quickly enough as engine RPM increases. When this happens, the valve stops following the camshaft profile correctly.

What’s Included in the Kit

While exact configurations may vary slightly depending on stock and specification, a typical complete kit includes:
