After being deafened by road noise from the OE tyres by 45000kms, I opted for a full set of Falken FK452's, got them for $150ea. Only issue was that they don't make 215/45R18s, like the stockies, so I went for 225/40R18.
I noticed a huge reduction in road noise, turn in and acceleration grip, and far better wet cornering. Even fuel economy seems better if averaging 60-80km/hr (above that seems worse). They did well at Wakefield Park during torrential rain (those 370z's, mx5's, etc didn't have a chance in the wet).
My 2010 VRX (bought in October) has now done 105000kms, and I'm about due for another 2 (left side outside edge is 1.5mm, right side 3mm). I'll be going for the same again.
My daily drive starts and finishes at the top of a hill with 3kms of hairpins, and these babies perform beautifully.
I noticed a big change in grip at about 45-50000kms using these, with regular rotation, which I figure isn't bad for $150 tyres. Admittedly, I should have changed them earlier, just too many things happening at the moment.
