That is like saying MLB approves of the Tampa Bay Devil Rays because they are a baseball team.
Now if these cars were antique massive v8's, then it might be an issue. But they aren't.

What do you mean which SFI? There's only one SFI, but if you want to know the actual part of the SFI specifications that pertain to dampers, it's 18.1. It's not marketing BS, SFI is a safety rating. Not that many people are going to be going faster than 10.99, so it's not really required, but most people would rather have a better made and functional part...

If these damper things were so great, why are they the only ones making them, but every company that can has a lightweight pulley of some sort? Seriously there is at least half a dozen different companies making a lightweight pulley for the 86.

Actually, no, it's not like the BBB, but it's apparent you're ignorant in this. There's a ton of different brands that make proper dampers, yet again, your ignorance in the matter doesn't mean it's not true. The reason lightweight crank pulleys are made and sold is the same reason there are a million different miracle cures for engine issues that are all nothing more than petroleum distillates... placebo effect and people want to believe.

And you're ignorant of everyone's background here, so why make remarks like this?

Haven't looked at any of these product websites closely have you? Nearly all have disclaimers about their products being for "off road use only" which absolves them of any claims of damage.

Why would they pay for something that is dramatically less expensive? Gee I wonder. Same reason the 86's aren't FI from the factory, same reason they used Prius tires, same reason everyone who wants to track it needs an oil cooler, etc.

The stock pulley is more expensive to produce than a simple pulley turned on a lathe. Yes, most of the aftermarket ones go out of their way to shave more weight, so they require a bit more machining than that, but the general point is this: if the OEM's could save PENNIES on a part, they would. The multi piece damper pulley could be made FAR cheaper if it didn't have the damper, so why is it there?
If you really think they're cheaper to produce, you might want to do some research...

It's a DAMPER, not a BALANCER. These are two very different things. It's there for torsional harmonics, not to balance an engine.
