Thanks for the suggestions but I am into some fiberglass myself you know
so I am going to build my own fenders as soon as I'll have the time.I can do it way cheapper and its my pleasure after all.
I have some J7 with 205 tires and 40mm adapter so I guess 4-5cms will cover the wheels nicely.
Its just that, at first site, too widened fenders(4"- looked funny on the supers, but now I am clear and it was a false impression.
Take care,
Martin
