So here is how the coupe sits now.
Original shocks, springs have been heated and it sits 3.5" at the front and 3" lower at the back.
The ride is firmer but NICER, not boaty as before.
steering is more precise.
I know, I know, it will affect the shocks but I don't drive the
car
that much and it is on flat roads always.
I think it sits really well and one shot compared to a regular height chrysler 300 shows how low is the merc.
Also pic before being lowered.
Cheers.
