I have a rather thick book that comes with my ERA. The history of the car, original documents, receipts, pictures etc. Well you made me 'drag out the book'.
I recalled a letter from BFGoodrich to ERA regarding testing of lateral G's. It's dated June 28, 1984. Running BFG Comp T/A's, 50 series, the ERA test car posted a 0.967 G on the skid pad. The letter noted this was signifcantly higher than similiar testing in the spring of 1983. BFG noted that this was a 'streetable' car and thus achieving such numbers was remarkable.
What I find even more interesting is that the BFG Comp T/A's are pretty well known for 'lacking traction'. In my opinion running Comp T/A's on a Cobra is just asking for trouble (spin out's, etc.). I am confident the test would have exceeded 1 G had they used "Bill Board" Goodyears!
When I first 'tracked' my ERA (Bill Board Goodyears and Side Oiler) I was absolutly blown away at how good it handled. The front stuck like glue, all the talk about Big Blocks being to heavy, blah blah blah, just didn't hold water. The cars handling was indeed 'remarkable'.
