I'd get the OE fitment 130/80 rear, I've tried the 140 which doesn't make a lot of difference except makes the rear end look a bit more manly! The 140 is also considerably more expensive than the 130 though, so not worth it in my eyes.

I'd have a go at fitting them yourself if you've got the time and inclination, the TKC I found was quite an easy one to learn with. It'll save you �30 and you'll pick up a useful skill that might save your bacon one day.
