Nah, no harm in what you did, depends where you live I guess. I'm not a massive fan of confrontation so I'd have left it as they could've had a blade, but equally they might just like nice cars.
PSC2 are MUCH better than the 888s for grip and feel on track, but then they do cost a fair bit more. If you have the budget and want a track biased tyre, they're the ones to go for.
That's the thing, on a 370 it's not essential to use 97+ at all. You can use 95 all year round if you like, aside from a smidge of lost power nothing drastic would happen. It's the DE engined 350 that desperately needs 97+.
Depends. Cup2 are the ultimate trackday special and this time they also work well in the wet, but on a GT-R would you want that much grip? If you want to feel the car move around a bit more, I think the MPSS would be the better choice.
Really does depend on what you want out of the car.
Depends on what wheels you have: The OEM wheels are the same width, the Rays are half an inch wider at the rear. Aftermarket wheels could be anything.
But yeah, the Zed can be tail happy but it shouldn't be that tail happy!
No! That's oversteer city and an accident waiting to happen, you must feel the rear has naff all grip and your TCS is cutting in all the time?
Go back to 225/245 F/R ASAP, I really wouldn't risk running the setup you have for anything other than an emergency.
Pretty much, yeah. It start off by making you feel awesome, and then you realise that your driving is so staccato that it's getting awful, and your transition to the power is terrible.
I bought one. Thought it was ace.
Three months later I binned it, as it's a pile of crap. Nothing beats your right foot in determining the amount of throttle you need.
