Gearbox Front Mount Bracket

We are making great progress towards completion of the Astra VXR engine transplant. The latest achievement is the design and manufacture of the gearbox front mount bracket. The chassis of the Corsa SRI differs from the Astra VXR is as much it doesn't have a crossmember running across the front of the engine bay. Consequently we have had to manufacture a bespoke crossmember resilient to absorb the torsional loads imparted by the 400bhp Z20 LEH engine. The final design is very innovative since, not only does it provide an anchorage point for the Astra gearbox front mount but also doubles up as an anti-roll bar, thus providing additional body stiffness. Yet again a fine example of Thorney Motorsport's engineering expertise. Once painted this crossmember / anti roll bar assembly will really look the part!
