Try the good old slightly slower in and progressive acceleration out, the car doesn't respond well to having to react too quickly and prefers the gentleman express route than the grab it by the scruff approach (as standard you have the wrong car if you want the ultimate rag it for a laugh machine). Things like understeer can be minimised by kinda letting the car know what is coming by not asking too much of the front too quickly............once the weight moves try not to move it again otherwise it can and will unsteady the car (exaggerated by a keen turbo coming on boost). Smoothness is the key to speed but doesn't always give you the satisfaction of having pushed the car hard.
Yep it bounces which is obviously suspension but it can carry pretty good speed without bounce in three figure corners but does wander a bit under acceleration, not ideal but plenty quick enough for most and for me is quite polite in letting you know and makes it very easy to tell when it isn't overly happy. Sometimes a softer set up is easier to push as you can more easily tell what the car is up rather than getting close to the limit without telling you along the way.
Like a lot of fast Audis the road surface makes a big difference to how the cars behave. ALWAYS remember the biggest improvement in time will come from you, not suspension setup, not the tyres but you telling the car what and how to do it.
Bottom line, go and have a play and try not to bend it.
