I was able to install my rear coil-overs but not the front yet and I was wondering if it would harm the car to drive with only the rears?

 

It's no so much the reverse rake that's concerning, although I imagine it looks kind of funny. The larger concern is driving around without getting the alignment done. So drive it slow, and as little as possible. Probably best to just avoid highway speeds, and you'll be OK.

 

The alignment seems fine and I have to take the highway to my job the whole week so I have to get up to at least 70-75

 

There's some irony here, asking for advice then claiming things "seem fine", and you'll be driving at least 75 mph anyway.

Dude, take a different route.

 

Coilovers are adjustable right? Why not adjust them to near stock ride height and install the front pair when you have time? If you understand there is a limitation, then you will adjust your driving accordingly.

Definitely do not push the car to this extreme: https://www.reddit.com/r/G37/comment...terday_on_the/
