Hi Oryx.
I use a DS3 and a similar setup - I don't use a traction control, but as the X2010 is incredibly grippy it doesn't make any difference apart from the very slow corners.
I don't claim to have completely cracked driving this car, I can't yet get the Golds on these challanges as yet, I just haven't driven enough laps in the car. Just keep driving it, forget the timer at first, keep lapping. The purpose of which is to get you used to the total vision and brain recalibration needed to keep this car on the circuit, let alone lap fast and neat. It does eventually come to you, I promise. Once you've got used to the mad late braking and banzai turn in speeds you can start to flow a bit.
Once you reach this stage you should be there. This car turns like a demon if you're on either the brakes or the throttle, but it's turn-rate is much less if you just hold a balanced throttle through the corners like you would in the road cars - so try for an agressive line where you brake late and hard, carry on braking nearly to the apex, and get back on the throttle pretty much immediately. This car needs it's chassis totally loaded to perform at it's best. I hope you'll find that the Bronze medals are not very hard if you put in a bit of time, and the Bronzes are good enough to use the car elsewhere...
