4bt 72 Dart

I'm not an engineer by no means, but the 4bt definitely vibrates a ton at idle, because they are like any other 4 cal that I know of that has 2 cylinders up and 2 down at one moment, an has to make up or can't make up that flat spot that 2 more cylinders at with the 6bt. But, as soon as it comes off idle it smooths out, and you would not even know it vibrates at idle. So, it not bad. It just makes your mirrors vibrate when sitting at a stop light. Or, makes a bread truck/step van sound like it's going to fall apart.

I have thought about rhino lining the floor, as I got that idea form someone on here, and would make cleaning the floor easier. But, I don't know how much it deadens sound, and I don't want it to be like the bread truck and sound like a rattle trap. For an everyday driver, it would get annoying fast.
