Not allowed metallic bearing anywhere (unless that way from the factory), except sway bar endlinks...which are unrestricted.
I haven't really read through the prepared rules, but if you can place in there it will be FP or XP. If you cannot run those in prepared...it is off to E modified for you. Either way....you will get absolutely crushed.

My funding fell through for a diff build this year. I figure a budget for it would be roughly $2k-$2.5k (clutch-type lsd, poly bushings and labor), and I had an unexpected significant expense on my DD.
So... considering that I've currently got
2007 HR Z
18x9.5 275/35R18 all around (tires in good condition)
Hotchkis swaybars
What would be a logical next step with a budget of ~$800-$1000?

I'm not fully prepped nor am I anywhere near a good enough driver to compete nationally, but here is my BSP build-in-progress on a grad student budget:

Powergrid Endlinks
Energy Suspension bushings on diff & all suspension arms F&R
Engine:
Momentum CAI
Kinetix Velocity intake manifold
UR Underdrive Pulleys
Kinetix HFCs (Megan longtubes are in the garage, but I'm waiting to see if the PPE longtubes ever hit the market)
JIC Spartan Ti single exhaust
UpRev Tuned
Drivetrain:
Quaife LSD
(Clutch/Flywheel coming later this season)
Brakes:
OEM non-Brembos
HPS pads
Wheels/Tires:
ARP Studs
17x10 +35 FN01RCs
275/40 Kumho XS
(Forgestar F14 18x10 or 11F/12R with A6s by mid-season)

I have actually. I measured a set that were for sale locally that I was going to buy, but the sleeve was too thick. Another user also measured the sleeve in the cuscos for me as well. I'm in Florida at the moment, but could pm you the measurements when I get to my home PC.

I don't have a dog in this debate as my upper bushings are homemade with delrin and a small steel sleve, but to play devil's advocate.....
The rule says Suspension bushings may be replaced with bushings of any materials
(except metal) as long as they fit in the original location. Offset
bushings may be used. In a replacement bushing the amount
of metal relative to the amount of non-metallic material may not be
increased.
If one were to account for the amount of metal in the inner AND outer sleve of a stock bushing would the Kinetix be legal?

13.5 B. The mounting hardware shall be of the original type. The use of
any shock absorber bushing material, including metal, is permitted.
Pressed or bonded bushings may be removed from standard parts
to facilitate the use of alternate bushings which fit in the original location
without alterations to the part. This does not permit the use of
an offset shock bushing. A shock absorber bushing may be implemented
as a spherical bearing. The bushing attaching the end of a
strut to the body or frame on a strut type suspension is a suspension
bushing, not a shock bushing.
15.5 C. Any shock absorbers may be used. 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. The installation may
incorporate an alternate upper spring perch/seat and/or mounting
block (bearing mount).

There are 2 exceptions to the metallic bearings.
13.5 B. The mounting hardware shall be of the original type. The use of any shock absorber bushing material, including metal, is permitted.
Pressed or bonded bushings may be removed from standard parts
to facilitate the use of alternate bushings which fit in the original location
without alterations to the part. This does not permit the use of
an offset shock bushing. A shock absorber bushing may be implemented
as a spherical bearing. The bushing attaching the end of a
strut to the body or frame on a strut type suspension is a suspension
bushing, not a shock bushing.

The rears yes and the fronts no. I don't have a copy of the rule book to quote right now, but there is a clause in the 13.5 shock section that if the shock supports the weight of the vehicle (coil-over or strut) then the bushing is considered a suspension bushing, not a shock bushing.
15.5 Only allows us to change the upper fronts to metal, not the lowers. I'm assume the allowance was written in for aftermarket adjustable strut mounts, but it says shock so we're covered.

Is it legal to take a BFH to the inner walls of the wheel well for tire clearance? I know it doesn't apply to Z's since the wheel hits the shock before anything else, but I observed a driver doing this to his BSP prepped E46 M3 this weekend. He's a guy that will be at national tours too.

Yeah, Brian and his codriver were taking a big hammer to the wheel wells before and during the morning runs at a test & tune this weekend. I'm not trying to be a whistle blower, just wondering if it is legal since I've always heard the "from the face of the hubs outward" rule.
They are running 295/315 Hoosiers, and it was apparently the first time they had attempted to fit or run them. I'll attribute that and the fact that it was a test & tune to me beating Brian by 0.3s and his codriver by 0.9s on a 30 second course in my Z on 275 street tires.

15.2 BODYWORK
Vehicles may only exceed the allowances of 13.2 as specified herein.
A. Fenders and bumpers may be modified for tire clearance. This includes
the portion of a hood which serves as a fender/wheel well,
where applicable. This does not permit modifications to the chassis
or bodywork inboard of the vertical plane of the hub/wheel mounting
face (at rest, with front wheels straight ahead). Flares may be added
although tires may extend beyond the bodywork. Replacement of
complete hood, flared fenders, or quarter panels is prohibited. Plastic
and rubber wheel well splash shields may be modified for tire
clearance and for installation of fender flares as allowed herein.
The rule is pretty much black and white.
