Dear Pro-touring,
I'm from Australia, and my car is a 1975 XB Falcon hardtop. In suspension layout, it is very similar to a 71-73 Mustang. This car is a weekend warrior and will be used for Auto-X (ratio of street/track of 60/40).
Due to the Australian design rules, I must stay with leaf springs if I am to drive the car on the street. Sure there are other legal options like the RRS torque arm, but I'm not convinced that it will be advantageous to a set of well thought out leaves.
I could potentially run a composite leaf spring, as hardly anyone knows anything about leaf springs where I live. I'm just not really sure if they are better than good quality steel springs. I'm really keen to hear some feedback, especially from Chicane.
Something, to me at least, more important than that is what kind of bushings would best suit my needs. Some people suggest monoballs in the front and rear spring eyes, with Del-a-lum in the upper shackle-to-body pivot. Others suggest solid front bushes with softer rears. Others still suggest rubber fronts with poly rears. Something that may effect the choice is my inability to run a lateral locator. There is no way a panhard or Watt's link will fit between the diff and fuel tank.
Thanks in advance for the feedback,
-Matt
