Nars, you are the man for compiling. I am very interested to see this data.

Should make the title be like "all owners please vote ...."

Bmwlmr99 · 12-01-2018, 10:12 PM

Great idea.... 2015 DCT VF stage 2 , downpipe, mid pipe, MPE exhaust , K&N drop in filters , CSF INTERCOOLER upgrade, charge pipe upgrade colder plugs and shorter spark plug gap.... 55,000 miles NOOOO ISSUES !!!

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.

Also voted.

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

r0wr · 12-07-2018, 02:24 PM

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.

M-Pilot · 12-07-2018, 09:38 PM

I agree that this needs to be a sticky. Maybe Jason or mkoesel can help.

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.

Currently 12 failures out of 107 votes.

2014 - 2015 DCT has 34 non-failed with 3 failures.

That must mean that probability SCH is close to 10 percent!!! /sarcasm

Maybe at least say what you voted for so that we know what not to count.

If you guys don't mind, and if you guys have the time, you may reach out to an Admin or Moderator to have your votes corrected.

IK6SPEED · 12-14-2018, 03:27 AM

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.
