how low u plan on going is the real Q
as for simplified answer, would prob wana get 2 extra guards already lipped on inside to max, and use them for rear (prefrebly ke70 front ones) or any 80's car that has similar look, lip or flare doubt ud need them to be flared for 8's and get old guards cut off completely and line up new ones 2-3 inches higher and start fabricateing, as for fronts, flare to an extend depending on ur camber tyre size etc, should watch mr2drift's thread for how hes doing fronts maybe not sure if hes tubbing or what.
