"Strakes" rolls off the tongue better than "deflectors" or "fender liner extensions" (the other common parts catalog designation). So strakes it is for me! And no "boots" or "bonnets" either, they're "trunks" and "hoods," dammit.

Boots and bonnets are UK usage, not really Australian as such. We take after the UK in spelling and word usage (and system of government too, actually).
