Help !!!!! K10 suspension

[gingerjack]

i have been looking around for months trying to find a way to lower my micra 60mm but the most i could find was 35 mm i heard that you could fit some polo coilovers on by drilling a hole and welding the other up then give it a nice spray finish, i do not have independent suspension so i will need lowering springs. does anyone know how i can lower it using springs for this car or some springs that may fit but i dont want to cut the springs. thanks
