Scale diagrams/measurements for 105 chassis/suspension?

[tjb0274]

Anyone know a source for detailed diagrams of the 105 layout, especially suspension?

I've been fooling around with some computer modeling of the Ricciardi, and have got a reasonable approximation of the suspension working (with some fudging for the t-bar), but don't have exact measurements for the mount points. I'd take measurements off my car but it's currently in Bayswater (plus it might be quite fiddly to take exact measurements of some of the less accessible parts).

Cg specs would also be useful!

Thanks heaps to Phil, who helped me out with some important info on dimensions 

Basically got the rear suspension done. The front suspension is still a guesstimate - doing it properly is next on the list. Couldn't (yet) figure a way to properly model the t-bar with the software I'm playing with, so I ended up using a single upper trailing arm instead, and a panhard rod for lateral location. However I put the panhard rod up at the height of the t-bar so that the roll centre is where it should be. So rear roll centre is correct, but lateral location may be slightly better than a real 105.

I've generated some rFactor suspension files to see how the model translates to (virtual) driving, and it seems pretty good (even with the dodgy front suspension). It was very interesting to move the panhard rod down to axle level to lower the roll centre - an excellent education on what lowering the roll centre does to the car. As advertised, the lower the roll centre, the better the power went down, and also the more predictable and catchable the car became.
