Holinger Engineering

Quickly becoming known for producing some of the best engineered transmissions and related products in professional racing, Australian firm Holinger Engineering gained worldwide attention during the 1990s as the gearbox supplier to BMW for its dominant touring cars. Holinger used its experience in high level racing to further advance their entire line of products. Holinger became the sole supplier of transmissions to the famous Australian V8 Supercar Series, and has continued since. These achievements did not go unnoticed, and more recently, Holinger's own sequential gearkit conversion to suit 911s was adopted by Porsche Motorsport and has become factory equipment in every 911 racecar they build. Holinger gearboxes and gearbox conversions are a dominant presence in GT3 racing around the world. Holinger gearboxes are successfully competing in the States in all forms of racing, from ALMS GT2 and SCCA Speed GT to exotic vintage specials. Holinger's line of racing transmissions is second to none. They are compact, lightweight and incredibly strong.
