Don’t want to trust just anyone with your racecar? Is your racecar your pride and joy? We understand! The team at THR Developments is not only made up of skilled, qualified professionals, but racecar drivers themselves. So now you won’t have to trust your car with just anyone, we are one of you!

K & A Motorsport is a team of specialists able to solve any problems that arise in the preparation or running of your race or rally car. We have a long and successful relationship with many of the competitors in V8 Supercars, Nations Cup, Marque Sports, Formula Ford, Formula Holden and both the Classic Adelaide Rally and Historic Marathon Rally events and we are able to help you too.

We are the Original Chassis service in Adelaide and still proudly family owned since 1959. It is our experience and pride in our name that sets us apart from the competition. We provide professional crash repairs, restorations and race fabrication for all makes and models but we specialise in Australian and American Muscle cars such as Chrysler Valiant Charger, Plymouth, Holden and Ford.
