the thread at http://www.bangshift.com/forum/index.php?topic=24147.msg396826;topicseen is debating the issue, and from what little I know, if it doesn't make the car go straight faster or quicker, than it's not a good side affect. Wheels off the ground is typically a bad thing, and regularly considered a waste of power to lift the car instead of pushing it forward... so I can't understand the people whose opinion or expertise states that this is a good effect... well it's brain candy, but that isn't why they are on the dragstrip is it?
