ID Front Suspension, ID Front Suspension Options

[FastFroggy]

Kind-of a newbie question here: How can I easily verify that I have 911 front control arms and front track.

I do have front S-calipers, vented rotors and hubs. Should a front track measurement suffice?

Thanks,

I believe 911 arms are the same as 914 other than the amount of splines on the torsion bars.

Mostly, the other difference is sway bar attachment.
When A-arms are so equipped the 911 non-through the body anti-sway bars have mounts that are not compatible with the OE style 914 bar & link attachment.

The 911 anti-sway bar doesn't go through the car's body and has different mounting points on the control arms, and this is easy to see the difference. The 911 cross member is aluminum (except maybe early 911s that had the smaller 3" spaced caliper mounting holes?).

Edit: never mind my comments about it having an aluminumcross member. I think the cross member can either aluminum or steel as both AL & steel are compatible with 911 or 914 control arms. Also, front struts of different types (pinch bolt and ball joints types, caliper fastener spacing, etc) are a different problem and can be replaced with other types. I guess I was in the mode of what came on the 911s in the 70s on one particular car, without mixing and matching things from different cars. So, never mind. (IMG:style_emoticons/default/beer3.gif)
