They are also 3g heavier than stock if anyone was curious.
there is also 4 width positions, not just wide and narrow

That would be like running RF In-C and RR Out-C on the new hangers. That's 5 degree of toe-in.

I did by mistake once.

It locked the car in so bad that it wouldn't turn.
I had to throw the car around the corners.

It did cause it to be unstable if you did not land a jump perfectly, it would also tend to get sketchy where the track was rough.

LOL I had no idea it was that much I would tend to agree that's a bit excessive.

I have the old hangers. I have wide and narrow in alum so I figured really had no reason to get the new ones. Did I miss something that was different with the new ones? Are there more options than the std wide / narrow?

I better go look at the first post!

IMO yes. Simply because you get more width adjustments and rear toe-in adjustments.

so there are more than just the std wide and narrow? Interesting. I would like to run a setting that's in between. I guess a 'normal' width for lack of a better term.

You will be able to do that. Actually there is 3 width possibilities between the narrow and wide aluminum hangers. Plus you can go even narrower and wider than those hangers.

Linked below are the instructions that are included in the hangers. Note the reference section in the middle of the page, to get the settings to mimic the narrow and wide hangers you typically use.

Yeah, the new ones are great, and much cheaper since you only need 2 hangers instead of 4 for narrow and wide and as already mentioned, get much more adjustment.

I'm assuming, combined with the V2 hubs aswell that the idea may be to not have toe adjustment in the hubs but in the hangers?

Do you supposed that Ty could be running the graphite front shock tower to increase front down-force, due to it not having as much open area as the plastic piece?
