What did you do for chassis stiffening?

Nice and easy, inexpensive as well.

I made a set for around 35 bucks, a little cutting, welding and done.

What a noticeable difference with them in. I noticed as soon as I backed out of the garage onto the street.

I plan on 2x3 stock and make them myself as well. I am also toying with making a new core support, from the tubing as well.
