I used to work for some V8 teams and supply tyres to them. They're relatively easy to drive up until you start to try to be fast and then they're a pig.
The problem is that they're traction limited i.e. the tyres are too small for the horsepower and weight. To get grip they make the springs as soft as they can without bottoming the things out on the bump stops so as to transfer load onto the rear tyres which means that they have to make the front springs soft as well which means they behave a bit like a large boat. They make the shocks really hard in bump and rebound to try to control the mass from rolling around however it means that its really easy to pick up front wheels in fact I've seen them "walk" the fronts down pit lane by just turning slightly and gassing it up slightly. The front just sits up and begs.
The real problem starts going into corners because your trying to brake hard and late, right up to the apex but it unloads the inside tyre which simple flat spots . Once a tyre is flat spotted it locks on the same spot every corner and goes bang.
They have to drive the car either square through the corner which means braking straight , turning hard and driving the thing square from corner or you float it through, maintain a high entry speed, rely on the front to turn it and wait till the car is straight again before you start squeezing on the throttle. Which one works depends on the driver but can be ditated by roll centres and squat geometry etc
I've seen new guys do 24 tyres just trying to learn how to steer the things. They're fine on fast flowing tracks but tight twisty walled tracks are hard, which is why stoner is struggling.
So it takes a particular style to drive the things fast which takes a long time to learn. But even once you get the hang of it it's still hard to get that last one second to get near the front and that means being "wired" for it. Race drivers refer to the ability to drive any vehicle at the absolute limit as being wired correctly to feel that knife edge. Stoner is wired for bikes not cars. Right now he's no better at driving a V8 supercar than you or I would be despite his bike experience. From a very young age Stoner was being wired to ride a bike fast on dirt surfaces which eventually gave home the bike control you saw in MotoGP.He might have the wiring that allows him to analyse his driving and make improvements better and faster than you or I but whether he gets the last 10% remains to be seen.
My guess is that he might make it into the main series but he might be a mid field runner at best and that totally depends on the team he's with. I would estimate that 90% of the performance is the car with the driver make the last 10%. How good the car is totally depends on the personnel in the team, the management structure and how much money you have.

I live with fear everyday but on weekends she lets me ride.
