The two men killed in a dramatic road smash on Brisbane’s southside yesterday morning were Greg Wright, 47, and Jarrod Hamilton, 27.

The pair was test-driving a powerful Porsche 911 GT2 for a Brisbane-based motor repairs shop when they lost control on Fairfield Road at Yeronga about 10.30am, slamming head-on into a passing truck near the intersection of Nelson Street.

They died at the scene.

Yesterday afternoon their employer, Fulcrum Suspensions, issued a statement expressing "great shock" at their deaths.

"On behalf of the entire Fulcrum Suspensions family we extend our deepest sympathies and condolences to the loved ones and friends of Greg and Jarrod after today’s terrible tragedy," Managing Director Graham Scudamore-Smith said.
