Might be worth shopping around first - about a year ago that set was under £140.
What tyres are you planning to use? I had originally planned to use 13" wheels and would've gone for 175/80/13's with white walls to make the wheels look bigger.
This is quite a useful tool for working out the effect different tyre sizes will have on the looks, clearance and gearing -

Anyway, have fun whatever you choose.
