I have a 2003 Mitsubishi Diamante.
I find that it rides a bit harsher than it should.
My shocks absorbers, suspension bushes, springs and strut top mounts are all fine (most are replaced with genuine Mitsubishi parts, bar for the shock absorbers).
To give an idea, even with original 160K mile shock absorbers it rode harsher than a friend's Diamante with lowering springs and sports shocks.
I upgraded to Boge/Sachs standard replacement shock absorbers and the ride got a little bit harsher, though there was much more body control.
The subframe bushes are original still and it is the only part of the puzzle that hasn't been touched so far.
But how much of this harshness can be attributed to these subframe bushes?
