solid and engine and trans mount guide
In my previous e30 I tore the rubber engine mounts taking a turn too hard.
In my current e30 I decided to replace the mounts with a solid mount.

I recommend replacing both engine and trans,
not just the engine and leaving the trans mounts stock or vice a versa.

lower nutit helps to turn the wheel, one way or another to provide better access to the bottom bolt.
Now that all the bolts are off.
start jacking the motor up, just enough for the old mounts to slip out.
Inspect the subfame and motor mount arms for cracks.
These motor mounts use a through bolt making the install a simple task.
apply a small amount of loctite to the nut to prevent it from vibrating loose.
dont forget to reinstall your heat shield.
I choose my skid plate.
