Hi all bough myself a spoiler for my i30 a couple weeks ago through these guys bodykitskingdom.com.au found them on ebay. I bought the spoiler for $120 and they painted it for me for an extra $100 so $220 all up and I picked it up within a week.
It is the exact same style of the factory one however it doesn't bolt on from the top and have the covers like I have seen with the factory one on here. I attached it using black Sikaflex which was very easy and it is not going anywhere.
Overall I am very happy with the result the paint is an exact match and great quality, however the paint does seem a little thin and I would have preferred a few more coats on it. Just hoping it won't fade to quickly in the years to come.
