wouldn't go for anything other than eibach, unless you really wanna spend some money, but given your 16 with a 1.2 there's no way your going to need it
spend some time reading through the threads as there are loads, but with eibach you've basically got sportlines and prolines
prolines lower slightly but make the stance more agressive and give far better performance, most state they almost eliminate body roll
sportlines compromise slightly on the handling and lower much further, front 40mm and rear 30mm however the handling is still far superior to the standard springs
i'd suggest sportlines as these will give you the drop you want to fill your arches more and the're about £140 -£150 a set, about £100 to fit, but i've put a tutorial up in the GP guides section on swapping them out, you only need a wrench kit and some spring clamps (£15 from B&Q) and its about a 3 hour job and can be done by anyone with a little bit of common sence
you should have gone for 17s with the wheels.. people say its bad for the gearbox but just dont drive like a **** and you'll be fine
as with suspension.. alot of people of here seem to have went with the eibachs and seem very pleased.. i went for KW adjustable coilovers, which were expensive (£650) but worth it.. fitted them myself in about 4 and a half hours for the full car
