I'm thinking about installing Roush extreme rear springs and Roush's regular front springs. This way I should get a 3/4" drop up front and a 1.25" to 1.50" drop in the rear.

This should level the car nicely, I am just concerned with mixing and matching spring rates.

What do you guys think?

 

Or, go with the BMR springs... 1.25" up front, 1.75" in back, and the car sits nice and flat...

 

measure your factory ride hight! theres actually only a 1/2'' difference from front to back if you go with your plan you might end up driving up hill and I wouldn't suggest mixing springs they have different spring rates ...

 

You should be fine. I have my front lowered 1.5" and my back is still stock height. I got tired of my side exhaust scraping on so many things that I put the stock springs back on. Been like that for a year now and now problems.
