I used the 002/003 springs on my 67 dart. I loved the raked look. I found the ride more comfortable than some newer vehicles. I ended up bending them at the rear eye so I had to replace.
I recently put on the caltrac setup with their +1 spring and I found the rear sat too low for my liking. I ended up altering things to get the rear end up at least another inch.
I do not have many miles on the caltrac setup yet so I can't make a case either way, but I know it seemed to hook hard on ny one test.
I do 90% street and 10% street launch (backroads)
I should also add I have inboard springs, mini tub and 325/50/15 tires.
