3 link or 4 link?

[jdwill13]

I was studying the pictures of the lateral dynamics watts link and notice the 3 link rear suspension. That is a work of art! I have a 91 Mustang. I want to make it the best handling machine I can. Is it worth converting to the 3 link setup or should I work with my factory type 4 link? I want to minitub it to run a 12 inch tire. With minitubs, watts link and tailpipes things are going to get a little crowded on a fox Mustang. Any ideas?
