Yes, you can start with just a rear strut tower brace, and yes, you will feel a pretty big difference with this mod. You can buy them from SHO shop, or you can do what I did: Take an old front strut tower brace and mod to fit and it only cost me 20$. Here's a pic:

All I had to do was built some mounting brackets and weld them to the strut towers, bolt in the bar afterwards and pre-load it. I liked this particular bar because it allows for more clearance through the seats.
