I noticed the 84 tends to follow the ruts in the road a lot more. Probably the big tyres.
Probably not a whole lot you can do about the rough ride in your 84 Steve unless you change out the front and rear fiberglass springs with softer ride springs from a later Vette.
The 1984 - 1987 Corvette springs interchange.
Are the shocks worn out on your 84?
Leaking oil ?
If worn out, be a good time to replace them.
They changed the Caster settings after the 1984 year. From 4 degrees positive to 7 degrees.
Was changed around 1986 or 1987.
My 87 calls for 7 degrees caster. Helped with straight line tracking and handling I recall reading from old C4 articles in the past.
Don't know if adding more caster to you 84 would help with straight line tracking over irregular road surfaces or not.
