I have a set of Goodyear Eagle F1 GS-D3's on my GTR at the moment. Done about 7,000kms on them and they are wearing very well. Don't know what funky is on about though, from my experience they are awesome in the wet regardless of how hot they are. Very confident of them in the wet, never feels slippery or aquaplaney.. They do tramline a bit, but I think most tyres over 245 size do that to a degree, GTR's i've heard are notorious for it too...
They are exxy but I was given wrong info on load ratings when I was looking which dictated me getting expensive tyres.. Still I'm more than happy with them..
