Last night we did a test fit, with my stillen exhaust it fits, I have to move the brackets outwards. Ill have to make a few custom brackets, which wont be hard. We might not need to remove the third light, we might be able to almost cap it with the way the diffuser is made. If you have a Nismo, Evo-r makes one for the nismo now, but not for the touring or base.
Once im off from work ill be going at it again, should have pictures up ASAP. Ill also do a DIY if it works lol!
If you look here, its almost like the diffuser will "cap" of the rear light.
