There were 2-specs of Nismo arches and splitters for the k11... a Wide one...
And a WIDER one lol...
After Nismo ceased production MULHOLLAND started to reporduce them, you COULD get hold of some but they are so rare is sick... I once saw an IMPORT micra with a set of just the arches on in london and stopped the guy in the street to ask him If he would sell them.. But he wasn't interested ..!
