Rough riding 1987 coupe

[Alfonso Gomez]

:crazy My 87 Coupe has new Monroe shocks and new composite leafsprings. My tires are Dunlops on stock rims, currently at 30 psi.
I find the car drives very rough. Will lowering the psi to about 25 help without damaging the tires? I know it is a sports car, but does it has to be so rough?:confused

25 PSI is too low.... If ride is a concern, you may want to look at a softer set of shocks... This is really the only way to get the car to ride better

I think 30 is probably too low, but IMHO 25 is DEFINITELY too low. You will see the tires wear down the middle at this pressure.

Is this a Z51 car?

Have a great day,
