I made no changes and found it perfect for autox, track days and street..
That's a cross-weight of 49.5%, which is pretty darn good. Several of the Cobras on here have had much, much worse numbers than that. I was one of the first cars to be put on Peter's new digital scales, back in 2006, and Doug was able to get me to 49.9% -- with pretty much the same conditions as yours, except the battery is up front. The difference of .4% is only 11 pounds, which is two gallons of gas. I agree that your car was pretty close to perfect right out of the box, but other cars around here are not so lucky. Maybe most ERA cars are where yours was, maybe they're not. The only way you know for sure is to check.
