The unique ground strap configuration on the E3 may provide longer life for a daily driver (more sharp edges to jump a spark) but that huge heat sink is not what most racers would select for a high performance engine, especially one using power adders. That's significant more mass to cool than the common "J" style ground strap which sheds heat quickly, especially the shorter "race" versions. A hot ground strap can cause pre-ignition. And I don't know how you would read that ground strap to determine if the advance is correct. On a common "J" style ground you can read the position of the color stripe to set your advance.

Use them and evaluate how they work. But unless you have a specific test methodology with measurable results all you're doing is going by perception which is unreliable at best.
