Could it be that it really isn't a good idea to go must faster than 155 in a Z, be it a Nismo Z or otherwise; at least not without some serious modifications?
I've been in various vehicles at very high speeds over the years; some were very stable and comfortable at those speeds and could probably cruise there for hours on end; and some were not so stable or comfortable...but all could "get there".
Just wondering out loud here.
