Redline Performance


In the early days of the automotive industry, you either ran what was available, or you fabricated something you thought met your needs. Such needs were the building blocks of this industry, and it was through the efforts of many that we have the automotive aftermarket, but it was through the work of one name in particular to which many in the Australian Aftermarket industry owe a great debt, and that name is Hardiman and the brand is Redline Performance.

Hardiman Auto Supplies Pty Ltd had its beginnings in 1959 as Hardrowl Speed Equipment. The business was run as a partnership by two apprentice tool makers, Terry Hardiman and Ian Rowley. Manufacturing commenced making lowering kits, panhard rods, traction rods, floor gear shift conversions, sports air filters, induction manifolds, ram tubes and the like.

In 1963 the very first speed shop in NSW was opened in the Sydney suburb of Beverly Hills. The Hardrowl partnership was dissolved in 1966 and Terry and Sylvia Hardiman commenced trading as Hardiman Auto Supplies Pty Ltd. In 1972, the original speed shop in Beverly Hills was expanded to more than four times its original size. Manufacturing continued and additional product lines were added. Importing from the USA commenced and the wholesale business continued to expand.  The retail business was sold in 1981. The manufacturing and wholesale business was then relocated to Milperra in 1981 where it remains today. Products are imported from the USA, UK, India, China and Taiwan and manufactured products are sold Australia-wide and exported to the UK, USA, New Zealand and Indonesia.

Under the Redline trademark, Hardiman Auto Supplies manufactures the largest range of inlet manifolds, carburettor adaptors and associated linkage components in the southern hemisphere. Over the years the manifold and adaptor range has been expanded by the purchase of the Warneford and Cain tooling.

In September 2005 Hardiman Auto Supplies Pty Ltd was purchased by Mark and Deborah Hardiman, the son of Terry and Sylvia. The new management team is very capable, Mark studied Electrical and Mechanical Engineering at University of Technology Sydney, whilst Deborah studied Information Technology and a Masters of Business Administration, she also studied Engineering Law and Design.
