Ackk!! Too many people autoX in the Pac NW! What's a matter w/ you guys in Washigton? Isn't there anything else to do up there other than autoX? 
I figure I'd get myself started on this thread as I'm trying to build an '07 BSP car for the '08 season. 'Trying' is the key word as it looks like other than Stillen's double CAI, there really isn't really much out there that will claim to be usable for an '07. Seems like most exhaust systems will bolt on from the cat-back but the '07 Y-pipe was supposedly redesigned. Is it possible that it's better than some of the aftermarket y-pipes currently avalible?

**I wouldn't have based what I thought was legal for BSP on this thread...just haven't found my reference yet. I'll post it up once I fine it...or maybe Ullose can chime in.

This what I got from a local autox forum when I asked if Cusco A-arms and Jic rear camber arms were allowed.
15.1 AUTHORIZED MODIFICATIONS
A. All Allowable modifications permitted in Stock Category are
allowed.
B. Street Prepared vehicles may only be modified in excess of Stock
Category rules in the following ways. Any modification not
specifically authorized by the Stock Category or Street Prepared
rules is prohibited. No unauthorized modifications are permitted
in order to accommodate authorized modifications (e.g., nonstock
hood scoops or holes necessary for carburetor clearance).
Structural modifications, such as the addition of members known
as “jacking rails”, are not permitted unless specifically authorized
herein.
F. On all forms of suspension, camber/caster adjustment within
factory specifications may be achieved by the use of shims or
eccentric bushings. The intent of this allowance is to permit cars
to be restored to within factory-allowed specification ranges, not
to provide an additional method beyond those permitted in Section
15.8 to obtain alignment settings beyond the factory specifications.
15.8 SUSPENSION
C. 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. This does not authorize a change in type
of bushing (for example ball and socket replacing a cylindrical
bushing), or use of a bushing with an angled hole whose direction
differs from that of the original bushing. If the Stock bushing
accommodated multi-axis motion via compliance of the component
material(s), the replacement bushing may not be changed to
accommodate such motion via change in bushing type, for example
to a spherical bearing or similar component involving internal
moving parts. Pins or keys may be used to prevent the rotation
of alternate bushings, but may serve no other purpose than
that of retaining the bushing in the desired position. Differential
mount bushings are not considered to be suspension bushings and
are not covered by this allowance.
F. The following allowances apply to strut-type suspensions: Adjustable
camber plates may be installed at the top of the strut,
and the original upper mounting holes may be slotted. The drilling
of holes in order to perform the installation is permitted, but the
center clearance hole may not be modified. Any type of bearing
or bushing may be used in the adjustable camber plate attachment
to the strut. The installation may incorporate an alternate
upper spring perch/seat and/or mounting block (bearing mount).
Any ride height change resulting from installation of camber
plates is allowed. Caster changes resulting from the use of camber
plates are permitted.
---------------------------------------------------
According to 15.1.B, if it doesn't say you can do it, you can't do it.
I quickly glanced, and no where in 15.8 (Suspension) does it say you can replace the front a-arms. It mentions the bushings in 15.8.C, but didn't see where the whole arm was allowed.
15.1.F and 15.8.F talk about camber adjustments. I also don't see where the camber arms are allowed.
So, unless someone knows better, I'd say they aren't allowed.

15.8...
H. Live axle suspension allowances:
1. Addition or replacement of suspension stabilizers (linkage
connecting the axle housing or De Dion to the chassis, which
controls lateral suspension location) is permitted.
2. Traction bars or torque arms may be added or replaced.
3. A panhard rod may be added or replaced.
4. The upper arm(s) may be removed, replaced, or modified,
and the upper pickup points on the rear axle housing may be
relocated.
5. The lower arms may not be altered, except as permitted
under 15.8.C, or relocated.

and just used that section for my reasoning to have rear camber arms...guess I need to take those off ASAP thanks for the heads up guys.
edit: just check the group that I run with, and it looks like they allow camber arms (I run in a combined ASP & BSP class that either uses SCCA rules OR the clubs modification rules)...so I think I'm okay as long as I don't run SCCA...which I hope to start doing next yr.

Wanted to resurrect this thread to get an update . . . having read the entire thread (again), I just wanted to get the latest clarification on a couple of items:
1. Upgrade from '06 OEM non-Brembo brakes to OEM Brembo brakes. Will this keep me in BSP?
2. Are after-market adjustable front camber arms allowed in BSP?
I have read the 2008 SCCA Solo Rules and the SP rules on these two topics are slightly vague.

Regarding the brakes, if you swap the entire Brembo brake system into your car (all that parts that are unique to the Brembo brake system) then its a legal swap in SP - IF all the models of the 350Z are on the same line in the car classification Appendix.

Page 84 from the '08 rule book:
"C. Equipment and/or specifications may be exchanged between
different years and models of a vehicle if (a) the item is standard
on the year/model from which it was taken, and (b) the years/
models are listed on the same line of Appendix A (Street Prepared
Classes). The updated/backdated part or the part to which
it is to be attached may not be altered, modified, machined or
otherwise changed to facilitate the updating/backdating allowance.
Standard factory installation methods, locations, and configurations
are allowed. The updating and/or backdating of
engines, transmissions or transaxles must be done as a unit;
component parts of these units may not be interchanged. Cars
not listed in the Street Prepared sections of Appendix A may not
be updated/backdated until approved by the SEB and published in
the official SCCA publication."

That's the reason I'm asking the question -- I've got an Enthusiast, which does not come with the Brembos. If I add the Brembos, then do I need to upgrade my Z to a Track/Performance level? I have TCS but no VDC. As far as I know, I think that's the only difference besides the track rims.

correct - you can just add the OE Brembo brakes w/out needing to do anything else.

I run BSP in our local Delta Region SCCA. I have an '08 Base with the following mods:
OE vlsd swap
Cusco A-Arms
Cusco Zero2 coilovers
18x10.5 enkei RPF1's with 285/30/18 V710s F/R
