heya thanks for replies, been away for a while.
thats good with the filing down of calipers, but yeah its been lowered 60mm i think, done by previous owner. which i can see will cause a bit of problem with rubbing. after a while of thinking, i'm pretty sure i'll be going with the 7.5s on the front. will make things easier and they're still more than wide enough :D
thansk everyone
and oh yeah
glad to say back on the road now. not too bad only cost £350, just need to get arch repainted after it was torn out :(
