Would your wife understand the need to go easy 'til the brakes have warmed up? The race pads may take some time to really bite! (though my Blues are excellent even from stone cold
)
Would have thought that the PF97s might be a bit extreme, as perhaps the DS3000's might be - you could try DS2500s (pretty cheap for a decent pad iirc) or Pagid Fast Road (again, cheap from GSF I think), or go for the Pagid Blues if you're feeling a bit more flush. (they're about £100)
If you're feeling seriously minted, go for a Wilwood 4-pot set up!
Are you going to FCS? If so you may be able to try some different ones out maybe?
Yoz has a selection you might like to look at?

The Pagid Blues on there that he recommended for me are marketed as a track pad but I've found them to be better than standard from cold and they never fade, giving me great confidence
Plus I think they're standard on the Lambo Murcielago
