I'd probably go to TDP but if I was you living in Dublin i'd also be thinking about East Coast Customs in Lisburn. There only 2 hours from you. Mapped my Evo 7 and done a very good job :)
You have to think about this, they white of the Rota Slipstream will be a different colour to the white of your EK9 and it won't look right at all. You would have to get them powder coated championship white to look good! BTW I didnt know you bought another EK9 Rvm :)
