Well the lettering is legal, it has a postcode and maker on it. its on reflective paper stuff etc. and the fact its such a deep plate it means that there is nothing within 11mm of each letter on the plate itself. the reason that they normaly dislike slogans is that they come closer than 11mm to the letters. Plus im sure that all those legalities are based on a standard plate size.
I previously had from halfords a set of "3d" legal lettering in legal spacing etc which is now illigal! the only thing legal is solid black lettering!
Perhaps i should just take off the plates and not get insured etc then they would go more leanient on me! hahahahaha.
In the end i like it and can get them for anyone who wants one like it from
Shane, call him at image Grafix on 01322 614669 and ask him to do a plate like the HKS lexus one, and he will remember, we spent 2hrs designing it, going thru a million changes. he was a top bloke and loves the car!
