I made this upgrade to my '06 Exige after living with lame A/C for six years because of frequent freezing up in really warm weather. The upgrade was worthwhile. My test drive consisted of a 630 mile one day round trip from SoCal to NorCal including driving Highway 395 for several hours through 105 degree temperatures.
The good news is that the A/C now works much better...big improvement in consistency of air cooling. Freezing up is no longer an issue, and there is just a steady stream of nice cool air. In more moderate temperatures (70s to low 80s), I can now leave the fan speed on 1 or 2 and don't have to turn the temperature dial all the way to max-cold...two to four clicks short of max-cold keeps me comfortable.
The bad news is that doing the upgrade takes time to just gain access to do the A/C upgrade. Exige front clam removal is actually a very straight forward and relatively easy process; it is just tedious and takes time.
Additional A/C related mods made to my car include sealing up the fresh air inlets (did it while the clam was off for the A/C thermostat upgrade), removal of footwell panels for better air recirculation, 4 inch tall heavy tint banner across top of the windshield, and the A/C inlet hose is fully wrapped in heat shielding insulation (redid it properly while the clam was off for the A/C thermostat upgrade). I may add 3M Cristaline tint to the side windows (did it to my Fiat 500's windows, sunroof and added a windshield banner, which reduced cabin temps by up to 25 degrees depending on sun intensity).
As Shawn C said, thanks to SirLotus for the R&D work and HocusLotus for the upgrade posting.
