It is quite time-consuming, you are correct, and is the reason for the 25-30 minute gap going from stock runs to modded, and 12 minute gap going from modded to stock. 61 sheet metal screws for the grill blocks and airdam/undertray, if my count's accurate. It was the first way I came up with for cheap and simple, and repeatably removable, unfortunately I sacrificed ease/speed for that. Not an issue in regular use as I only need to remove them for oil changes or tire issues.
For the testing I brought along a cordless drill with a flathead screwdriver bit that it came with, and a freshly charged spare battery. Otherwise the removal/attachment would have taken much longer.

Where I live we have real winters but we also have 90 degree days in summer and use the AC a lot. We'll be interested to hear if you have to remove some of the blockage for hot summer days. Years ago I owned a 3cyl Saab that had a window shade device in front of the radiator.

I'm very interested to know this as well! Temps here range from -40 in winter to mid 90s in summer; 40 degree swing from low to high is common in the summer. I plan either on leaving the opening as it is until we get to the hottest days, or making louvers that are adjustable from inside the car so I can keep it optimum at all times (possibly with a second one for the AC side). Inspired by The donkey CRX in this post
http://ecomodder.com/forum/showthrea...tml#post421965 and others in similar projects. I'll be sure to keep up-to-date info on this post. Was the Saab's window shade device stock? I hear some modern cars now have auto-adjusting grill blocks as standard features.
Finished the driver side rear skirt last night, went to aero test them this morning but got too discouraged by winds and traffic. Got a better picture, at least.
