Yeah its god damn farken TERRIBLE!!!! Altho most of it is down to the farken stupid Dunlop tyres the idiots at ford continually use as OEM tyres. I've had the OEM SP9000's on my 18's which are noisy as all fark. The SP3000's they fit to the 17's on my previous NA XR6 were exactly the damn same. Sit on a freeway at 100km and you need to crank the stereo to drown out the road noise. Currently have Bridgestone S03's on the front and they are tops, i thought the car was a bum dragger with the SP9000's but the S03s have knocked out a lot of the understeer from before and they seem lots quieter.
As for reading whats on the forum forums, of course they are gonna love them. Be like coming on SAU and asking if skylines are any good hehe.
I've had my current BA2 XR6T since Dec 04, and other than the average panel fit, terrible road noise and drinking ~20L of oil in the first 15,000kms, its generally been ok. Its ok to cruise in, did many trips to NSW in my previous NA XR6, but they're not much chop if you enjoy some proper driving. (Being a dickhead on the skidpan exempted hehe)
If you can live with driving something that has the dynamics of a brick on wheels, go for an F6
Keep in mind if you do the edit thing etc, its gonna drink like all fark.
