Re: Nissan GT-R Officially Revealed
The only weakness that I think the GTR quite possibly may have is its weight. Short stints as on roads or low intensity laps on track may not show it up, but it will be interesting to see how in say TCC 40 min enduro events at SIC with a decent driver, how the laptimes degrade (or not) over longer stints.
The impressive Nring quick time doesn't prove tire 'unfadeability', Nring has a number of long straights (cool off periods) dispersed throughout the lap and weather was cool IIRC when record was run... all helping tire life. I'm also quite sure that for such a big track that time or distance spent under lateral accel. as a ratio to total lap time or distance, is smaller than most tracks. IOW, other tracks have the potential to be harder on the tires per unit time or distance. Your're taking somewhere around 200-250% longer by both time and/or distance to yaw the car 360 degrees CW > CCW (since CW track) at Nring vs a typical track say SIC.
Electronics have a big influence on transient balance and all that, but very small one to absolute grip and steady state balance, so majority of energy input the same and compounds equal, I see trying to accelerate an extra 300 or so kg (a lot) in rapid succession (due to lots of power) as something that will hurt it in anything long term.
I don't know anything about the GTR tire construction, size, inflation pressures, but anyone with access to the car could easily measure patch areas and if its static total patch area to vehicle weight ratio is considerably smaller than other cars in class that run more typical weight, then there is strong probability that tire degradation in longer stints will be an issue. The good news is that this sort of operation is lowest on the list of any street car owner especially a commuter car, and there is no requirement to ever run it for extended stints in order to enjoy the car. It's just the cherry on the top for some, but for others not even a consideration.
