At Pfadt, we are not just content with building products that look pretty. We design all of our pieces to take car of problems and needs that you Camaro has. There has been a lot of talk about fabricated control arms for the rear suspension for these cars. As is typical for Pfadt, we started by looking at the factory pieces to see where the deficiencies are.
Here is a rear trailing arm (the toe link) shown with a 1000 lb tension force in it. A realistic cornering load. The deflection in the steel arm itself is 2.4mm. That is obviously not conducive to good handling and cornering feel. The deflection amount is almost exactly the same in compression. The shadowed arm in the photo shows the displacement (multiplied for visualization).
Armed with this information, we decided that we could stiffen up that arm with a simple, inexpensive DIY brace.
With the brace installed on the part, the deflection is reduced to less than 1mm with the same load.
Here is the same analysis of the toe link with the brace in place.
Look for more fabricated control arm pieces from Pfadt in the near future, complete with the analysis to back them up.
