My suspicion is that they will - the 'slots' will act a little like a plane (spelling?).
If you don't want to admit you just liked them (especially to SWMBO), you could also try:
- lighter, less unsprung weight, therefore better handling
- better heat dissipation, therefore less fade and safer
- better braking, due to the slots that lead to the increased pad wear
These may all be bo!!ox, but may help with the Finance Committee - or you could just say I like them!
