If you decide to go for some flared arches, then the best fit are from Marugen Shoukai... They do a Standard, Deluxe and Wide "ZG Style" which have a great reputation
As Jay says, Marugen Shoukai are the only ones to go for. They are moulded off original factory ZG overfenders, so are accurate and of high quality and fitment. Forget all the cheapo generic ones - they generally just look bad.
