I run eagle F1 Asy2's and cant recommend them enough. They are quite simply astounding.
Not had them on long enough to see how well they've worn, but i had a set of GSD3's on an old car and they wore just fine. The treadwear rating on them is "300" which is fairly comparable to most high performance tyres.
If your looking for a cheaper tyre, then IMO the Hankook S1 Evo is the one to go for.
Its fairly new (unlike the Falken) and did really well over the last few years against many more expensive tyres.
I've never run FK452's but i have driven on Kumho KU31's, which were similarly "bigged up" as a super amazing budget tyre on other forums. However they dont hold a candle to the Eagles, especially in the wet.
If your wanting a GOOD tyre, then i'd consider the Eagle F1 Asy2, Conti SportContact5P (or 3 if the 5P's arent in your size), and Michelin Pilot Sport 3.
If your wanting a cheap tyre, then the Hankook S1 Evo is where its at.
Anyone still recommending 452's are simply stuck in the past and unwilling to try new things, IMO. Better products exist!
I do find it amazing that people on here spend all this money tuning up their cars, yet fitting some cheap rubber ruins the whole experience. End of the day no matter what you do to the suspension, brakes, engine, etc etc, everything relies on those four squares of rubber pressing onto the tarmac. Cheap out there, and everything else is wasted.
