I have been working on a little side project with the rear sway bar on my 1200 coupe. This time I'm trying with a bit more of a mathematical approach. I am going off the advice of a good friend who is a racecar engineer with the baseline spring rate matched to the rear suspension roll centre and rear axle travel characteristics. I am planning on fitting up a calibrated part from "Schroeder torsion bars" based in California USA. They are the choice of sway bar for many racecar categories e.g. nascar. The torsion bars come in calibrated diameters and when matched with the appropriate 4130 chrome molly or 4005 alloy arms [which also come varying lengths], can be identified with a known spring rate. All of the technical data is available on the schroeder torsion bar web site. i.e., spring rate tables and response curve charts.

This could all end up being a total disaster with having all suspension components adjustable, trying to dial in the ultimate set-up. Different set-ups would suit different tracks and or different conditions on the same track though. Just have to start recording the set-ups and outcomes in a notebook for reference.

Anyways I plan to post up the findings once I get the bar fitted up and hopefully translates to better lap times. Plan to fit one the front as well at some point as well.
