“Never sleep with anyone crazier than yourself”. It is one of those bits of wisdom that is meant to make you pause and consider the consequences. But at the same time it is kind of a compliment because you can imagine it’s the sort of thing Keith Richards would say to Mick Jagger (or vise versa). I am not cool enough to need a warning like that. The warnings I get are more like “don’t wear brown shoes with a blue suit”, and in the case of suspension work, “seek out lots of advice.”
The real focus of this post arrived about 6 months ago when I received a set of full floating rear A-arms for my CAV monocoque. These upgrade parts were purchase from Ian Clark at CAV-Canada. A few posts on the forum with pictures and comments have already been made by Ian so I will not repeat that information.
I immediately did the installation, drove the car for a month and was really pleased. As crazy as it might sound, the overall affect was less. Going through corners, the car just felt more stuck to the ground with less bounce, and steering required only smaller micro adjustments. I assume the bounce through the corners was from the stock rubber bushings alternately compressing and expanding and now that movement is gone. This is not to say the ride was softer, but it was much flatter without wallowing. Although I have spent a respectable amount of time racing, this was the first time that I have had the opportunity to feel an A/B comparison. No wonder that CAV racers add full floating rod end suspensions. So now I am a convert and think that these A-arms may become the single most important change I will make.
So for Part III of the project I have A-arms from CAV-Canada. I also bought a set of larger and stronger trailing arm yokes from AutoFutura. And finally from the same source as the motor mounts and cross member, I bought a reinforcement bracket that bolts to the bottom half of the rear uprights. Each of these parts does something good.
This picture shows the starting point. Fresh from shipping, this car is a little dusty but with the drive shaft removed, all the relevant early design parts can be seen. The flat steel crossmembers were previously replaced with a single stainless steel box section described in Part II. The stock lower A-arms are V shaped with rubber bushings and no cross bracing. The uprights have an external frame. The smaller trailing arms yokes can also be seen. All of these pieces will change. I will remember to not wear brown shoes and to not let the car fall.
