I know the nismo is love hate, IMO I love it I got mine done not long ago. I got the oem removed which damaged the boot lid and required a respray. The nismo has 2 bolts that fit with the oem spoiler and if your car is a nismo it will have another 2 bolts at the top. If not then it will no doubt have been bonded on or worse, had holes drilled into the boot lid. Your boot will 100% need a respray after you take it off unless you are getting a spoiler to cover it, I don't know any other spoiler you can get with a bigger base than the nismo... my advice... keep it wrap the wing carbon fibre or something.
