Hi guys, im over from the Mk5 section - hope you dont mind me commenting!
I have FK452's on my MK5 GTI - i find them perfectly fine! Yes, they aren't the last word in wet grip compared to Conti's and i haven't tried the Vredesteins although i've read good things. In the dry they give me confidence and there isn't much road noise on the m/way.
I would like to try the Vredesteins but one i wouldn't try are Goodyear Eagle F1's - i had them on my last car (Fiat Panda 100HP - OEM fitted from new!) and i found them absolutely shocking! Worst tyres i've ever used - wet grip was non existant and they lasted 6k miles at a push!
I think i would try Vredesteins next, but the FK452s are ok - not shocking, but not the best i've used
