My take on C9 setup,
trying to improve things, first of all, pretty impossible.
Getting gearing, tyre temps right is obviously important, trying not to get power oversteer, or the nose of the car to respond is another matter entirely.
Tried Riek setup, got the same time as my set-up, the only differences were some of my corner entry and exits had to be readjusted.
Reik seems to like it more pointy and more tail-happy car setup, but as the car is tail happy by its nature that did not affect my driving much at all.
My set-up for the LMPC car and most cars I drive will be completely different to Andreas, which implies I need a far more stable car, that implies that generally speaking, I will be slower.
That I accept, so my setup for the C9 is really only about one thing, trying to make it 100% stable.
Unfortunately, that is not going to happen, so I try for as stable as I can get, and just have to deal with its wayward nature on the circuit.
Hoping I can keep my concentration going 100% for 100% of the race, difficult.
So a long-winded way of saying you can make it slightly more pointy, you can aid that with rear roll bar stiffness, then deal with the performance-enhancing rear instability for increased cornering speed, both of which I am trying to get rid of; mostly unsuccessfully.
Look forward to reading Reik response.
PS
That is taken for all Group C cars here on AC, easiest is the Porsche ST, almost a very fast GT3 car, but without TC, will sometimes bite you.
Then the Mazda, but needs a lot of rear wing, which seems to negate all of its advantages, then the Porsche LT.
Hardest by far is the C9
