Doesn't it sit rather low in the back?  

it is pretty loaded down in that picture. 5 gal of gas on the back and a big box full of gear in the back. If i take that stuff out it comes up to level. i'll try to take that stuff out and take a picture tonight after work.

Did you reinforce the strut "towers"?

On the stock front end the coils go between the lower arm and a coil mount attached to the frame rail - so that strut towers simply hold the top of the strut - when you go to a "coil-over" as you hvae, you significantly increase the loading on the towers.

I did not strengthen the strut mount. However if you look at this picture

you can see it is already a pretty well gusseted mount. And i still ahve the factory strut bar. This all combined makes a strong structure to hold the spring. The stock spring mount is is actually built into the strut mount as well and they are both attached as one piece to the frame.

Here is the car without all the gear in the back. It sits up quite a bit higher

Nice!
