I would say it falls under 16.0

O. Any minor modification, intended to allow or facilitate any allowed modification, is permitted as long as it does not provide any intrinsic performance benefit in and of itself, does not provide a weight reduction of more than 1.0 lb., and is not explicitly prohibited elsewhere within these rules.
This rule is intended to allow minor notching, bending, clearancing, grinding; the drilling of holes; affixing, relocating, or strengthening of brackets; removal of small parts, and similar operations performed in order
to facilitate the installation of allowed parts or modifications. Minor strengthening, without relocation, of original chassis/suspension pickup points is allowed. Examples include welding washers restricting control arm mounting bolt movement, local reinforcement of control arm chassis mounts, etc.
Competitors are strongly cautioned to make the minimum amount of modification required to affix a given part and to not make unduly tortured interpretations of this rule. Modifications to the firewall in order to allow for increased engine setback, and any modification that changes the location of a suspension pickup point, are explicitly forbidden. Plastic under-trays and covers below the vehicle may be removed or modified as necessary to facilitate other compliant modifications, but not added or enlarged.

Front subframes are open provided the pick up point doesn't move. Removing spacers would move the location for the suspension pick up points. However, we're talking about a Forester here so no one is going to actually protest you.

I'd guess the lack of camber is something got missed/flipped/moved during the arm install that caused it. A bend in an arm big enough to make that sort of change would be visible while eyeballing it.

Keeping the inside rear on the ground is usually not the fastest way to make a Subaru go around corners in AutoX when you have aftermarket diffs. On anything resembling a gear type rear diff and rules that don't allow a change, then keeping the rear on the ground is faster to a point.

The suretrac isn't adjustable is it? I thought the suretrac was a cam/pawl design and they switched to the torsen in the 05+ cars for increased longevity. It certainly wouldn't be as easy as a plated diff, I guess

I went down the “keep the inside rear on the ground” rabbit hole on my STU car. Ultimately got it to be pretty decent like that but I don’t know that it was any faster than it was when it was picking the inside rear up. Yeah, it didn’t hop and do funky stuff on corner exit but it was compromised in other ways (wasn’t quite as good transitionally). If I was doing it again, I’d put a diff in the rear and run a different class.

Can't say yet... Also only have a few miles on it and was stuck in traffic and cars were approaching way too quickly. The speed is blinding and I still need to wrap my head around it.

All I can remember is it felt a touch laggy and then boom you get punched in the nuts with torque and then it just pulls and pulls and pulls.

Sounds like every garrett based turbo out there (blouch line, 20g, etc).

I laughed at the can't say part.

Now imagine an extra 100 wtq 1,000 rpm sooner (if you had an EFR)

On the new setup I could do more if I used a 7163. Think well over 500 wtq for that turbo. The old setup is a single scroll 6758 and produced the numbers I quoted.

But yeah, that curve looks like a LOT of other turbos I've seen. I'm not poopooing it, just saying it's nothing new, especially on a DAVCS car.
