This car-track-tyres combo was more like ds3 drivers go buy a wheel...
All my testing is done with a wheel, so this certainly can put DS3 users at a disadvantage, at times.
Mainly, I just try to change things up, so far in GT5 WRS -
None of the cars or tracks were available in Prologue
One World circuit, one Original Circuit, one City Course
One week with N tires, one week with Race Tires, one week with Sports tires.
One road car, one race car, one tuner car
One week with tuning, 2 weeks without tuning
2 FR drivetrains and 1 AWD drivetrain
That means you can expect to see some MR cars and FF cars in the coming weeks. Along with a range of HP.
So far, these have been difficult combos in general, there will be some easier ones later.
As for the walls, see my comments in the first post. Wait to get back on the gas a little longer than you think you need to. I had to run about 10 laps in testing to get a clean one, but once you find the marks for braking and throttle input, it's a smooth and flowing combo.
