on standard tyres a 1.0 micra will slide, and squeel and roll all over the place. the very last thing they were designed to do is corner well.
not only that but they dont come with very good anti-roll bars. they have soggy suspension and its probebly worn out the bushes too.
first thing to do on any car for handling is the tyres. some 14" wheels off a civic with some decent tyres on would be a cheap option (bout £100 or so) then some suspension, eibach and bilstein streetline kit for £350 is a very very good option for road holding and lowering (about 40mm)
next would be the bushes,. nissan ones are available but not very good for handling, nismo ones are better and are available from matt humphris (

lastly would be anti-roll bars, these are available from whiteline and can vastly improve handling. you can also go the full hog and get the caster kit, camber kit, adjustable trailing arms, lower strut brace, upper strut brace (makes lots of difference in roundabouts) drop links and panhard rod so you can adjust everything..
but its all about the monaay, its all about the dum dum dada dum dum.
