Meant E36, just a typo.
All things being equal the 128 would have the slightest edge in cornering. The weight difference is so minor its not really negligible. Especially since the 135's power more than makes up for it.
As for braking, its not an equal thing. The 135's brakes are much larger and have better calipers than the 128's. They are better for the street and limited track use. And yes, before someone else chimes in, they sometimes have issues with extreme track usage. Even still, they are much better than the N/A's cars setup.
Most of the things you talk about are your(or others) opinion of a car. You say that the handling is better with the Z06 over the ZR1 but using your C&D list there, its basically a matter of ones opinion.
There are many who could claim the the ZR1 is better handling, opinions based on your criteria. I'll stick to track times and other measurable data(along with personal opinion) to reach a conclusion. For me, the 135 has my vote in spades over the 'high winding'
I seriously doubt the 128 is faster around any track than the 135.
