I had GSD2s on a FWD car and GSD3 on FWD and RWD cars. I do agree from experience that IMO the GSD2 are a longer lasting tyre, but maybe that was where Goodyear thought their improvment lay, obtaining better grip at the cost of tyre life, although for day to day running, I couldnt really tell the difference.
I would never recommend F1s for a 4WD car like a Subaru, thats just pure idiocity IMO, super soft side walls, all of them being pumulled at the same time by a hell of a lot of power. OK, that may sound like me saying dont put them on performance cars, not at all, but 4wd vehicles need serious (and ongoing)suspension tweaking before they can wear a tyre like the F1.
I remember being a passenger in a 911 (997) wearing special order only 295/35ZR 18 Fronts and 305/30 ZR 19 Eagle GSD3 F1s. They had been on the car for 12,000 and by no means driven 'conservatively'. They looked brand new, and I can honestly say I've never been in a car that gripped so well. Why, the owner of said porsche ran his own Tyre company, including equipment for 4 wheel laser alignment, costing somewhere in the region of £150,000 for this machine to prep race and rally cars.
He knew what he was talking about, and his Porsche was treated once a month to its suspension being rigorously checked.
