Hardiman Auto Supplies

Hardiman Auto Supplies Pty Ltd had its beginnings in 1959 as Hardrowl Speed Equipment. This 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 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 Ashford Avenue, Milperra in 1984 where it remains today. Products are imported from the USA, UK, India and Taiwan and manufactured products are sold Australia-wide and exported to the UK, 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.

In September 2005 Hardiman Auto Supplies Pty Ltd was purchased by Mark and Deborah Hardiman the son of Terry and Sylvia.
