I did the search thing and today, Search is not my friend

My NB8B has 54000km on it and is stock except for a MX5 plus twin hoop roll bar,, most of my driving is local weekend stuff and although I'm happy with the Handling of "the Girlfriend"
(its the only one my wife will let me have) I thought I would tap in to the wealth of knowledge that this forum brings and ask what is the best bang for buck handling mod.
I was thinking whiteline sway bars as a good place to flatten the cornering without stiffening up the ride to much, but you guys are the guru's
Over to you
Cheers
Dale
