The item is a RS*R 4 inch back Box.
I bought of a friend of mine here in briustol who had it fitted to his IS200 for 3 months then sold the car and put it back to standard. i picked this item up off him but to be honest it is not really my cup of tea. i will be fitting it to my car next week for a couple of days to make sure there are not problems holes etc and if there are they will be sorted so it will be in a1 working condition to the person who buys it. as normally with me offers please i can arrange shipping of buyer can come and pick it up. Please PM me if you have any questions.
here are some pictures.
