One need not transfer "all" the weight (if you did the car would be sliding on its nose). If you cornering at or near the limits of the tires, a lift at speed is more than enough for the rears to lose grip. People spin all the time on track from such behavior. As others have mentioned, the R is a sort of inverted 911, there's a relatively big lump out on the bumper which with softish springs, motor mounts, etc should amplify the effect. At high speed, recall TE said this was a high speed trait, as presumably the R is not a positive downforce car, if the rear is sufficiently light the effect could easily be further magnified. Who among us knows the DF figures front and rear at say 110? What TE described sound quite reminiscent of the early TT spoiler debacle.
I have no reason to doubt TE, but for those that do, just head over to WGI, go flat out of 1, as per usual stay flat through 2. You should be at least 110 as you turn in for the esses and go over the hump. Lift to taste. Its uphill, you'll have a fighting chance. Please have some form of video and logging on board so we can amuse ourselves with video and enlighten ourselves with the data traces.
Having seen the carnage that can occur up in that part of the track, I know I ain't going to try that in an R or any other car with or with out esp. But perhaps someone here wants to sacrifice their R for science. If nothing else, you'll get a lot of youtube hits.
