Spoiler for 2018 sedan
 

Hi. We have just bought a 2018 sedan, delivery in a week or so. We had a 2013 hatch back a few years ago, it was very good so we are happy to get the new GT which looks to be very plush inside and a really nice package. I want to put a spoiler on the boot - does anyone have an idea of where to get one? I have looked at plenty of images but dont know what is reputable. I also told the dealers to take off the stock alloys and leave on the steel rims as I will put on some aftermarket rims. I'm thinking 17"s - has anyone had experience with them and how it affects the ride and know how wide we can go without it being an issue? My daughter will have the car most of the time and could live with a firm ride, within reason.

Any help would be appreciated!
