im no expert but i see what you are sayin, but isnt one of the benifts of trail braking is to shift the weight to the front to allow the front tyres to grip better in the bend allowing faster cornering, this maybe were the extra weight of the v6 may be benifcial in which the r32 just grips and grips if you can master the entrance of the corner
Not on a front engined car, no.
In a 911 or similar...then yes, you brake late and hard to bring the weight forward and add grip to aid turn in.
In a predominantly FWD, front engined car you hit the limit of what you can expect the front wheels to do quite quickly (braking, turning etc) so trail braking allows you to send the weight of the rear outwards - almost like trying to promote oversteer, but with no driven wheels.
You want the rear to stasrt to rotate, or come round on you, so you can grab a half turn of opposite lock (straightening the wheels) and get the power back on hard.
In my experience, more nose weight is never a good thing in a front engined car...it only ever leads to more understeer.
