NT-05R or just the regular NT-05?
i had them and didn't like them as much as the RII's for drag racing, they were supposed to be a track tire but not as good as the NT01
$105k staring isn't that bad
$75k for a dark Horse with the handling pack
You get an upgraded 5.2 engine, DCT transmission, all the cooling upgrades, a supercharger, cats that don't melt, etc for another $30k
Never heard of it. Are you thinking of an oil catch can?
If so, that has been discussed many times

Sorry for reminding you the ZR1 is faster, everywhere. Now people are leg humping modified GTD times (or they don't realize it's not a production car) and trying to compare them to stock ZR1 times.
When someone says the GTD is faster in the turns or would be faster than the ZR1 if it had more...
