For some time, one of the CC members here (a/k/a a427AC?) known to me as "Cheeks" did a lot of open track work with his ERA. He eventually had it tricked out with fuel cell, cage, little race windshield, etc. etc. and had it dropped so low that he had the
oil scoop duct taped on so it wouldn't break anymore of the body when he took it off on the slightest little hickup in the road. He balanced out the chassis with lead weights. If anyone knows how to set up an ERA, cheeks does.
