Is it true that 18inch alloys will fit the fabia vrs and if so has anbody had this done? and are they any better than having 17inch alloys?

They will fit, but personally I wouldn't go any bigger than 17's. Having lower profile tyres to suit would make it a very hard ride.

18" x 8" on 215 x 35 x 18.

Hope that helps.

If you want to retain some handling, as has been said, don't go more than 17".

19" also fit, but must be 7.5" wide rims, and 30 profile tyes.

Cheers for your replies.

The 18s do look good
