How did we get from an "other than engine........" discussion to "one's just better"? lol, wtf I guess we are stroking egos now.

When it comes down to it, at the road course, the ZL1 only has an advantage from center of the corner out to down the straights. I'll say it again:Since the OP asked about non-engine track component differences that engine advantage is a moot point to the discussion

Talk of different half shafts, prop shaft, eLSD tunes, ECU tune, exhaust tune, gearing, brakes, brake lines (?), fuel lines, forged internals, blah, blah, blah are all inconsequential to the original discussion.
