55.2-59 what year C4 suspension to use

[55_truck]

What year C4 suspension did you use and why?

I know the 84-87 Corvette suspensions are approximately 1 inch narrower (then 88-96) and have 11" rotors allowing for smaller rims. The 88-96 are wider and have 12" rotors.

Reading online the 84-87 are closer to the stock width of the 55.2-59

Any advantages of using suspension from one year to another?

I know the Dana44 was introduced in 1985, so i guess that would be the earliest year wanted.
