Leave camber where it is for now;
Lower my (hot) pressures in the front to match the rear approx 34-35 psi all around;
Move the rear bar to the softest setting;
Trail brake into corners to help rotate the car which will now have more rear end grip;
Get on the power earlier -while in the corner or earlier at exit- applying lock as needed as I wind out of the corner.
A lot easier to write about then actually do -but still have to ask- Am I getting close?  |
Be careful with trail braking. Done properly it can help with entry rotation. Done incorrectly it will understeer. This car is not mid-engine, so the rear wont rotate that much on entry without a bit of rear rebound. Remember that the front tires have only so much available grip for braking and turning.
On tire temp reading, think of the tire mold and how it deals with heat. The inner and outer blocks of the RS4 are large and retain more heat, the middle block is small and dissipates heat faster. I'm willing to bet that the middle block was actually hotter than what was measured on the track so lowering front and maybe rear pressures does make sense.
As far as operating range for the RS4, I remember something like 160-180(?) but I don't totally remember. Would have to talk to a Hankook tire engineer since they don't publish.
I would mess with the pressures before anything, I think.
