Tyres make soooooooo much differance !!! Loose the cheap shite tyres and it should solve 90% of issue Alot of people complain starlet are oversteery but i beg to differ, mine used to understeer everywhere (chassis isnt brilliant impo) Loosing your strut brace in rear will make very little differance in my opinion also Seriously, get some decent tyres for rear and run them at correct pressures and (if you actually know how to drive) Should make a world of differance
