I'm not a big fan of the T1-R either, but the CF-1 seem to work well on a non sportpack 156.
I tried Falken ZE502s years ago on my Giulietta and was distinctly underwhelmed. I appreciate they likely have nothing in common with the FK452s, but they certainly performed nothing like as advertised. It put me off Falkens, and I've seen only a moderate improvement with a later type of Falken.
I think the GSD3s are hugely better than NCT5s. Perhaps the cornering speeds are just 10% quicker, but they feel leagues ahead to me, and comparable with any other UHP tyre. I know of a written off 155 which had a major oversteer off the road although it had never
oversteered before. GSD3s on the front, and NCT5s on the rear. All fitted 3 days earlier. The pressures were correct.
Vredestein Ultrac Sessantas should have the Kumhos all over the place and armfuls of oversteer (or perhaps not being a V6?
) I wouldn't like to say yet, but it sounds as though the much lauded Sessantas are nothing to shout about, and/or the Kumhos really are quite good.
We all have our preferences for our experiences, and I'm sure car setup and driving style play their part too. The choice is yours.
BTW, it doesn't matter if it is SO2s or SO3s on a TVR. From my experience, the Chim lets go pretty quickly- only slightly more user-friendly than the hardcore Griff
