Aaah ! thank you for the clarification. Is Replacing the Stock LCA bushing Allowed in SP ?

15.5C .... Shock absorber mounting
brackets which serve no other purpose may be altered, added or
replaced, provided that the attachment points on the body/
frame/subframe/chassis/suspension member are not altered.
....
MacPherson strut equipped cars may substitute struts,
and/or may use any insert. This does not allow unauthorized
changes in suspension geometry or changes in attachment
points (e.g., affecting the position of the lower ball joint or
spindle). It is intended to allow the strut length changes needed
to accommodate permitted modifications which affect ride
....

My goal is to spend around 500ish on suspension adjustments (since i have a set of RE070s, and 2 spare RE070 tires , i'll find 2 more with similar tread depth online) and the camber bolts sound cheap, and an alignment isn't that much money .

what i read on IWSTI cody was 1 bolt lets you adjust your camber .75, using 2 bolts you can adjust it 1.5 (i'm just repeating what i read though) but it also warned that if you use a top bolt with the bottom bolt you mess up your Caster and it warned against doing that for autocross. (it said you will get more positive camber during body roll becuase of a bad SAI. Although you are specifically allowed 2 camber bolts in the SP Class (and camber Shimmies ??? i don't know what a shimmy is )

I also saw a suggestion for replacing the Diff bushings (rear and center diffs i assume) again i don't know why that would help. perhaps less of your power would be used up in diff movement, and more would make it to the wheels. (i think at this point more power won't help me at all, just seat time, sticky tires and Re070s are pricey enough!!, and maybe a few adjustment tweaks, and more seat time)

Thanks for the offer on the ALK btw, do you have any stuff laying around to sell that won't bump me out of SP ? lmk

(sway bars? , strut tower braces?)

Thanks again for the Camber suggestions. i'll call up subaru tomorrow and see what the stock suspension even allows for camber settings and go as close to what you suggested as possible.
