Astra H VXR Stage 3 Upgrade and LSD (Limited Slip Differential).
This car spent a couple of days in our workshop and had a full 3″ exhaust system, CSRacing intercooler and a Quaife LSD fitted. Then it was onto the rolling road for mapping, datalogging and full rolling road set up making 290bhp and 350 lb/ft torque.
