In my area it is above 100 degrees from the end of June to the beginning of September. I'd like to do something to get those temps down now before I end up over heating on the side of the road. The only problem is that I'm on a budget so I need to keep these mods cheap.

So, what's your best bang for the buck cooling mod?

I'm thinking so far of raising the concentration of water in my coolant, maybe adding water wetter. Hood louvers? Oil cooler? Anybody know a source of massive aluminum radiators that fit these cars?

Any and all help is appreciated.
What is the current status of your cooling system? Have you flushed the coolant? Checked the thermostat? Cleaned the radiator fins? Made sure your fan clutch is working?

My first reaction is that those temps you are seeing seem pretty high in below 100F weather.
