I am considering updating the suspension system while I have the car apart but am not sure what, if any modern suspension upgrades might exist.

Anything to make the ride a little bit softer and give the car better agility around corners.

right now I have mono leaf springs, front discs and rear drums.

There is a huge aftermarket for making the first gens handle better. The sky (and wallet) are the limit for what you can do.

Getting a softer ride and better agility don't always go hand in hand though...

For many people companies like Hotchkis make systems that more then fit their needs. Here is a link to their 67-69 firebird products http://www.hotchkis.net/search.html?...mitForm=Search

They would in all honestly be your best bet as a starting point. If you want to learn more check out some other car forums like

I would also look into Global West. Speak to Paul, he can answer all your questions.

My advice would be to first look at David Pozzi's authoritative overview of First Gen suspensions, what's wrong with them, and how to make them better.

factory rating springs and rubber bushings for a nice ride.

Front and rear antisway bar with poly bushings. Good shocks with poly bushings

A mild change in steering box ratio and effort

Good Eagle or BF Goodrich radials
