I did the same to my estate only rear wheels but i did on 15mm spacers
I am a fan of understated mods and I honestly think 15 mm would be a better fit for our cars. However I didn't really feel like going through the extra hassle of taking them off, returning and re-ordering new ones. Don't have as much time to work on the car as I used to before.
