firstly, there's no such thing as a 1.1 furio lol, do you mean 1.1 forte?
secondly, it all depends on how mechanically minded and experienced you are?
for the rear, google badgermotorsport lowering or suzukituning lowering guide
for the front, theres a guide with pictures on here somewhere. Search spring removal guide in the suspension section
Its also worth noting, that unlike most other cars, its actually quite expensive to slam the front of a saxo (providing you want to keep it looking level and not look a douche)
Coilovers are required for the front for anything more than ~60mm, and cheap coilovers arent very good
