Agreed and as well as the lugs being ridiculously large, the colour looked dreadful, avoid.Wonder why it took so long, I got mine really quickly. But as The_Saint said, the official surround is the way to go, mine fit in without an issue. The aftermarket ones I tried were cr*p (no matter what the supplier said about how good it is).
No explanation from Seat about the delay, I was told it was going to be a "long, long time" when I ordered though so I can't in fairness say I wasn't told.
