Lowering 1999 monte carlo z34

[Aydenn]

I'm lowering my 1st car 1999 monte carlo z34, but there's zero companies that make coilovers for the car, I know it shares similar properties to other w body cars. has anyone ever lowered there's? I was thinking on putting 1999 Grand Prix coilovers on

Do you specifically want coilovers or just want to lower it?  Intrax, Suspension Techniques, and Eibach used to have lowering springs for the Monte.

Eibach 3836.140
Intrax 25.1.024

Sadly, all discontinued, but Google did pull up a few webpages claiming to have the Eibach kit still.  I wouldn't bet on any of them being legit, but who knows.

Might have to do custom coil-overs using universal parts or do what I've heard a lot of people do and chop a coil off the stock springs.

I don't know how they did it, but D-body Cadillac Fleetwood guys figured out what generic Moog springs get the desired lowering on those cars.  Something like S10 front springs and Crown Vic front springs on the rear.  No idea how they came up with that.  Either a lot of trial & error or careful calculation comparing specs and such.
