'Good quality wheels' and 'reasonable price' do not go into the same sentence with eachother, unless you are talking about second hand Works/Rays/Wedssport/etc...
XXR 527's are way too over played on Liberty's, if you look at a few members cars you will soon find they are on nearly 1 out of every 2 or 3 Subaru/Mitsubishi/Nissan
They are definitely not a good quality wheel. Yes they will be fine for every day driving in terms of holding up to potholes and every day abuse but thats as far as it goes.
In terms of fitment, you won't get them to fit properly unless you plan on running a bit of camber (not cheap) and doing some (not exactly cheap either) guard work.
Id first off suggest doing a little more research on this forum in the
The Gen 4 Wheels Thread to find out what spec's will fit without blowing out your budget.
Also, one last point. Don't be a sheep, get a different style of rim other than XXR 527's or Rota Gravels/Grids. Thats not to say don't get Rota's or XXR's, just have a think about different styles
