I'm in the same boat i have N/A starlet and my first mod was springs and new standard shocks, it made a difference but not enough to stop the car rolling about though. next on the shopping list is rear anti roll bar if i can find one for the right money!(anyone have one lurking they dont want please PM) after that will be front ARB to either a standard Glanza/GT(bigger diameter than standard N/A) item or Uprated(bigger still) whiteline one .
