I had 94's on the rear previously and you can tell when you put the correct load rating back on what difference they actually make. Not that I am an expert however the stiffer sidewall does seem to make a difference to the handling. I have read all of the posts previously re. tyre selection and agree that you do not have to go with the premium brands to get a good tyre choice for good everyday use, But there is little point as far as I see it in getting something of an inferior load or speed rating - particularly when it comes to money v safety. The Accelera Phi are supposedly excellent in the dry but treacherous in the wet. The Falkens I have on my partners Polo and they do not give you any reason to notice them (a good thing). I was originally going to get the Hankook Ventus V12 Or Vredstein Ultrac Cento which if you read any review on this forum, will tell you that they are excellent tyres. I did not go with them however as apparently they are of no use in the snow (in opinions read). In my opinion the Kuhmo's I got are better (less noise - better handling) than the Goodyears I had on previously (note: the 94's on the rear where only temporary to avoid confusion) and the Goodyears where of OEM spec. The Pirelli's that it left the factory with however where the best but I would have paid a dam sight more for not that much gain.
I think that you will be fine with the Falken's (£141 fitted) however you should definitely be good with Hankook's at £157 a corner. For some reason though I cannot find Kumho's for sale in your size anymore but if you search the forum you will see many good opinions of them. I paid £450 for 4 x Kumho's fitted in my driveway (225,50,17 98Y).
