if comparing our 2 VXR's, the corsa is a great little, well not so little mini hot hatch and with the remap has made it more enjoyable to drive around in but it cant match my stage 3 astra in performance or the handling of the kw coilovers i have fitted but saying that the corsa would handle just as well maybe even better than a stock astra, both fun cars.
The brakes are standard at present, will be sorting out the pads and fitting braided hoses shortly.
