As TB says, no info re the variants on conti's website. Plus they are universally hailed as being noisy. My experience with conti SC3 on a FWD Focus ST was less than favourable. They did ok, but certainly did not make me feel like they were worth the extra premium that I paid. I am very tempted to try these next:

They score highly on quiteness, wear and have above average grip.
In 2 yrs of owning a POS Focus, and all the friggin ones I've been stitched up as hire cars, nothing will make any Focus do corners. Inherrently shite. Much improved on the Escort, granted, but still utter shite.
But back you the main bulk of your post, SC3 are far quieter than the Dunlops I use on the MV6. If you want quiet, I'd recommend Falken 912. Very quiet. Until the emergency services sirens break the peace, and rush you to hospital.
Generic tyre reviews mean absolutely diddly. Thats why I go out of my way
not to read them. What works on a FWD shitbox probably won't work on a 2t exec saloon. Additionally, even within the same model of tyre on the same car, load ratind and even speed rating can make a dramatic difference. This is my my little Rover, RIP, used P6000 V rated, even though its top speed was within the H rating, as the P6000 H rated was shite - fortunately a short lived, albeit expensive, mistake, as they only managed about 8k. 8K of pure understeer though, so fun was had

Additionally, everyone wants something different from their tyres. I mean, FFS, people actually choose Michelin. I assume these people are depressed and want to end it all, but there are more reliable ways to top yourself

.
I know what tyres can produce the levels of grip, both cornering and stopping, that I am looking for, now just have to find something thats more durable than the Sport Maxx TT's I use on the MV6 (which are a stunning tyre, but too expensive to replace annually/10k).
