Nostalgia time again; I've dug up some more history lessons.
Fred Gibson teamed up with his wife to run an ex-Brock A9X hatchback at Bathurst in 1978.
The car preparation budget, including initial purchase, was approximately $25,000.
The A9X race car wasn't as highly modified as the 1980's Group A touring cars. Gibbo's car featured an Ian Tate built 308, with the L34 specifications carried over to the A9X. Still, the race prepared engine cost around $6,000. It breathed through a 830cfm Holley carburettor and was good for "about" 283kW.
Brakes featured standard A9X rotors with Girling racing calipers and specific Hardie Ferodo pads.
Wheels were 15" diameter / 10" wide Aunger Hotwire alloys, fitted with Dunlop 592-compound slicks.
Front suspension featured very stiff coil spring replacements and a thick anti-roll bar, with Koni brand double-adjustable shock absorbers. The rear suspension utilised coil springs that were relatively "soft" with a tubular anti-roll bar and Bilstein gas shock absorbers.
The standard Holden gearbox was used, but the differential was a "Detroit Locker" with 3.08 ratio.
Other variations from the road A9X included fully welded body seams, integated roll cage, additional dashboard instrumentation, a Recaro driver's seat and centre floor mounted fire extinguisher, and the big 130 litre alloy fuel tank with quick release flip cap mounted in the usual Torana location.
The car's interior still featured the standard front passenger bucket seat, with the rear seats folded flat and cargo area carpet still in place. Even the steering wheel was the standard SS/SLR/GTS item.
Quite different from today's V8 Supercars.
