Title: Suspension Geometry
Post by: gizmo on May 19, 2007, 09:36:03 pm

I now have my car on a level garage floor and I've started to take measurments from the suspension (front and rear). The thing is I can't find any information on what the factory settings were. Can anyone help me with the following:

Ground clearance,  castor angles, camber angles, toe in or toe out settings and the king pin inclination.

Many thanks

The Espace Murena web site contains a scan of the workshop manual, but unfortunately they haven't scanned the part about steering, which is where the numbers are. But this is what I have in my (German) copy of the manual:

Front:
Caster: 4°±20'
Camber: -0°20' ±10'
Toe in: 0 - 2 mm

Rear (not adjustable):
Camber: -1°30' to -2°

These measurements are specified under the following circumstances: Full tank, 40 kg in trunk, 2 x 70 kg in the seats. This should result in the following clearances:

Front: 153 mm
Rear: 201 mm

The clearance on the front is adjustable, and is even in a section that has been published on Espace Murena :) Take a look at this:

Following page shows how to make the clearance measurement:

I think this should get you started ;)

Can anybody clarify for me how much 0-2mm is in degrees/minutes ?

I find the handling of my murena very lacking, with severe instability in crosswind and at motorway speeds.. so I tracked it today and it said +26' in both sides.. 

The camber of the front wheels were off by -20' ..(-53') but the same in both sides... can the camber be adjusted in anyway?

Just set it up so the toe-in is zero.
