I took the Astra 2.2 SRi round Castle Combe yesterday, I was surprised how good it was on track.
The suspension (standard) was great, it didn't lean much and the power seemed better than on the road probably becuase I was always above 5,000 rpm, and the rear end felt quite light too :thumbup:
Overall it was very satisfying, a fun trackday car even if the 911 Turbo's and Evo's all came past lol
