IIRC you can reconfigure the weight of the steering via tech2....altho tbh ive forgotten sooooo much in the past two months from leaving Vauxhall to go work on Peugeots that I could have just completely dreamed that one up
Seriously though, im sure you can reset it to sports chassis to make it alittle heavier....there was three different options as far as I recall, one being sports chassis, another being a learner car and cant remember the third....this was on the Corsa D, but may also apply to Corsa C.
Either way...dont buy a Peugeot, they are utter pants in every respect
