I need a set of ultra light 15s for drag racing. I know the stock sawblades I mounted my 23" M&H slicks on weight 19 lbs each, so anything around 10-12lbs would be perfect.

 

Since you didn't specify if price was an issue so I'm just going to list some wheels that I know are light weight (some may be expensive):
- Advan Racing RG(cast) - 15x6.5=10.5lbs 15x7=11.4lbs
- Buddy Club P1(Forged) - 15x7=10.1lbs
- Desmond Rega Master EVO(forged) - 15x6.5=8.6lbs
- Enkei RPF1(cast) - 15x7=9.1lbs
- Konig Helium(cast) - 15x6.5=11.5lbs
- Kosei K1 Racing(cast) - 15x7=13.5lbs
- Mazda Millenia takeoffs(cast) - 15x6=11.5lbs
- OZ Superleggera(cast) - 15x7=11lbs
- Racing Hart CP-035R(SSF) - 15x6.5=8.6lbs 15x7=9.4lbs
- Rota Slipstream(cast) - 15x6.5=12lbs
- Rota Subzero(cast) - 15x6.5=12lbs
- RS Watanabe Cyclone(forged mg) - 15x6.5=10.1lbs 15x7=10.4lbs (http://www.rs-watanabe.co.jp/index2.htm)

Are lightweight wheels like some of the above suitable for daily driving? I suspect so.

 

I'd get forged lightweight wheels if you have potholes in your area.

 

Yeah I have tons of potholes in my area which is why I am keeping the sawblades for the street. They are heavy for 15s but they are also mad strong.

 

No potholes where I'm from. JClaw please see my question in your other post re: Yokohama tires.
