It's hard to get everyone to participate in general no matter how catchy the subject line is... I've already requested for a sticky, so we'll see what the mods say.

It's unscientific, but it's better than no data at all.

Thus far, ~ 9.6% of all voters have spun crank hub. Ouch. Scary stuff. ~20% of people running 550whp+.

Keep the votes coming! Sticky might be helpful!

Those are not nice numbers at all. Was hoping to see a lot smaller. Hopefully it'll drop as more users vote. Def needs sticky

I clicked the wrong option on accident and I can't change.

And we obviously shouldn't take this poll as a proxy for the likelihood of SCH given inherent bias of an enthusiast forum.

I'm sure that is highly skewed as people with a spun hub are more likely to come in here and make it known. There is no way 1 in 10 F8x cars suffer from this, nowhere near that.

By my very rough count, eliminating 2snails, 15 failures out of 120 voters....or roughly 12.5%

assume that higher than reality in general population.

Scanning looks like more on 6MT than DCT.

If everyone who viewed this poll voted, then the ratio would probably be more like 1%.

With that being said, let's get more votes in to get a more accurate estimate.

I believe I alluded to it being higher than general population.
