I've had my 67 289 for over three years now and I want to start a project upgrading the suspension to make it handle a corner and making it more fun to drive in the twisties. Currently, the suspension is stock, but my lower ball joints are wearing out and so I am about to replace the lower control arms. I figure since I have to replace them anyways it probably is a good first step to upgrading my suspension. I've been doing some research on what it out there. I've looked at Global Wests products including their tubular lower control arms. So my question is for all you guys and gals who have their cars setup to handle. What setups are you using? What do you recommend for lower control arms? I don't really have alot of money right now so this project will take awhile. Basically tell me what you know are the keys to making a mustang handle, thanks. 

.....sorry..carry on.......
When it's ALL said & done, TIRES are the single biggest variable though.
