Thinking of doing a similar sort of thing but much less subtle. In fact I had started with the GT101 stickers and some Eibach stickers but I had to have the GT101 ones removed when I have the wings resprayed.#
I was basically going to fill the gap from under the 5.0 badge to the stripe with logos. (black ones of course. Great thing with logos is all you are risking is a little money as you can take them off if you dont like them.
I do think the samples you have put up are a little big and stick out a bit too much on the white so for the reason I would go with option 3
I also wonder if you will end up with the car looking too busy and cluttered on the bottom half and then just plain white on the top. This really cries out for some OTT Martini stripes.
Whatever you go with, it will look eye catching and all that really matters is what you think but like me, I am sure you care what others think.
would go full on - if you only do half it looks a bit chavtastic to be honest.
martini is cool livery, I would go for it. If you want some options chat up Badhand on mfuk. he is an excellent artist with photoshop etc. He may charge you but at least you have something you like and can take it to your strip company and say this is what i want
