There are a few, but not that many. Also, there are no such rules when it comes to importing, just taxes and paperwork in general. The only rule I can think of is excise tax, which is 3.1% for cars with an engine under 2 liters and 18.6% over.
About mods coming to the car, I've already bought Tein Flex Z coilovers and TE37s S Plus in diamond dark gunmetal (front 8.5" x 18" +35, rear 9.5" x 18" +22). Rims will be here in March. When the car arrives, I'll probably do a custom turboback and some exterior mods. I will keep you updated on my progress here! :)
