At what point does one need to seriously consider this modification? 500hp/tq and beyond etc...?

The great unknown. It's impossible to know for sure.

Ive heard numerous people even complain about spun hubs on stock power but then I've also found those same people to be lying and have actually tuned their car (just didn't want to be caught out for warranty purposes). It's impossible to know for sure.

To be safe I would say the general consensus is stick to stock and keep your warranty as long as you can and if you tune, at all, get your crank hub fixed. If not this method, a capture plate at minimum. Anything above stage 1 then go the full hog.

impossible to tell, if you are extra safe i recommend doing it after the car is stage 2. Most wait till its time for a turbo upgrade

So stage 1 on CA 91 octane would be relatively low risk without this modification?

That's my personal opinion but I have no data to back it up. I have seen this part fail even on stock cars.

There have been more than a few people who've had crank hub slip with stage 1 tune. It seems to be more prevalent on DCT cars but still happens on manual.

It's an expensive upgrade but the down side is huge. Once it is installed the s55 is extremely robust and takes to large power upgrades very well.
