Having been looking through some old japanese websites i had bookmarked, i have come accross several nice rc's and nc's or pics that could give some ideas for mods. Can not understand one word of em though so best just click and hope.
There fairly old so you may have seen em before. I will add more as i find em. Many of these sites have link pages to other owners sites. I am only posting the best ones.
