btw your rear wheels seem a bit narrow for a 315.

thanks for the info!

so are these "offset control arm bushings"...if so, how much for a set??
A spoiler/splitter may be added to the front of the car below
the bumper. It may not extend rearward beyond the front
most part of the front wheel well openings, and may not
block normal grille or other openings, or obstruct lights.
Splitters may not protrude beyond the bumper.
"Splitters may not protrude....." was added to the '08 rule book. A pan under the nose back to the wheel openings may still be worth a little something.

Something along these lines with the diffuser(s) dumping into the wheel wells might help:

^ thanks for the heads-up. That rule change would make life A LOT easier in the front AND rear camber department.
Can we comment on 2 proposed rule changes in the same letter? There's a certain reclassing issue that I need to comment on..... rally cars=ASP

Koni DA suspension
Hotchkis sways
17x9.5 SSR Comps with V710s
NISMO LSD
ST BBK for track days
Light pulleys
Plenum spacer
MD Shockwave ))) y-pipe and single side exhaust (on the way, swapping the NISMO)
Bride street tuner YO race seat
3060#
^ Koni DA's?
Truechoice Phase IV coilovers
Yes they are based on OTS Koni yellows, but the valving and R&D was done by the Unitech Grand Am 350Z team. In addition to setting the valving they also spec'd the spring rates (I know your running Dave's setup which had stiffer springs and valving). Plus they have shortened case and piston rod lengths.
I didn't know your were running BSP.

I just registered my Z for it's first autox! I've done autox before, but in another car. The event will be in July, so I'll have time to bring the car up to specs (I hope). I have an 03 Touring.
I registered mine in BSP with the following mods:
Hotchkis sways/springs
Crawford strutbar
Crawford plenum
JWT intake
custom single exhaust
Motul DOT 4 fluid
braided brake lines

ok this may have been discussed elsewhere, but I haven't found anything super relevant.
from the 2009 scca BSP rules:
so camber arms are specifically allowed now. Looking at designs, i think the SPL's (the new billet ones with shims) "look" fantastic, but the drawback is the spherical bearing which is expressly prohibited in BSP. Kinetix and stillen (and a couple others) make nice front arms that would be legal, but i dont like their method of adjustment. I have found screw in poly bushing insert rod ends (a bushing that replaces a spherical brg. rod end) on a couple of camaro/mustang and off-road sites, but they aren't offered in a variety of sizes.
Has anybody converted spherical bearing arms to poly bushings to legalize them?
also....
Does anyone want to comment on the potential legality of using the SPL adjustable camber arms IN CONJUNCTION with their adjustable rear toe arm with adjustable spring mount if both were converted to bushings? I think the z33 rear suspension has a design mentioned at the end of the quoted passage where 3 lower links are doing the work of a lower a-arm, which if i read into this correctly, allows me to change two lateral lower links for the price of one.
from the 2009 scca BSP rules:
G. Camber bolts may be installed, providing these parts use the
original, unmodified mounting points. Caster changes resulting
from the use of camber bolts are permitted.
H. Camber kits, also known as camber compensators, may be
installed. These kits consist of either adjustable length arms or
arm mounts that provide a lateral adjustment to the effective
length of a control arm. Alignment outside the factory specifications
is allowed. The following restrictions apply:
1. On double/unequal arm (e.g. wishbone, multi-link) suspensions,
only the upper arms OR lower arms may be modified
or replaced, but not both. Non-integral longitudinal arms that
primarily control fore/aft wheel movement (e.g. trailing
arm(s) or link(s) of a multi-link suspension) may not be replaced,
changed, or modified.
2. On arm-and-strut (MacPherson/Chapman) suspensions, the
lower arms may be modified/replaced OR other methods of
camber adjustment as allowed by paragraphs 15.8.C, D, or G
may be used, but not both.
3. On swing or trailing arm suspensions, the main arms may
not be modified or replaced, but lateral locating links/arms
may be modified or replaced.
4. The replacement arms or mounts must attach to the original
standard mounting points. All bushings must meet the requirements
of 15.8.C. Intermediate mounting points (e.g.
shock/spring mounts) may not be moved or relocated on the
arm, except as incidental to the camber adjustment. The
knuckle/bearing housing/spindle assembly cannot be modified
or replaced.
Note: Many modern suspension designs known by other names
actually function as double A-arm designs. These include the
rear suspensions on 88+ Honda Civic/Integra, Neon, E36 BMW,
and most ‘multi-link’ and are covered by 15.8.H.1.

I am bumping this back from the dead...with the "new" class upon us I feel it relevant once more.
In the interest of sparking more sharing here is my set-up. So far as I know...only Michael Bright and I have cars ready (for the most part) to go. I'm finishing up some things for the Dixie Tour in a few weeks.
Set-up as it will be for Dixie:
Suspension:
Motons with 900/750 hypercoils (Hopefully they are here....if not I'll be on my Truechoice double koni's)
Factory A-arms with offset bushings
Hotchkis front bar (full stiff)
SPL Endlinks
No rear sway
Alignment...info to come
Engine:
Pop Charger w/80mm velocity stack
Samco Intake tube
Z1auto 3" MAF
MD 5/16" Spacer
UR Crank Pulley
Z1 2.5" Test Pipes
TurboXS Y-Pipe & Exhaust (only weighs about 19lbs...too my surprise)
Tomei V2 Headers
Tuned Osiris/Uprev by Hills Garage
Will be converted to E85 once we get summer blend in MD (June)
Drivetrain:
Cusco RS at 80% lock
OS Giken Super Single w/Aluminum Pressure Plate (Pretty light....~25lbs for the whole assembly with flywheel)
Brakes: Too my understanding, what I have on my car is legal per 15.6 of the 2012 SP rules:
Stoptech 332mm front BBK (2 piece rotors) and stock rear non brembos
Stoptech lines
Stoptech pads
Wheels/Tires:
ARP Studs
18x10.5 +15 RPF1's
315/30 Hoosier A6's (hoping to have 315's for Dixie...if not I have a set of sticker 285's)
Will be upgrading at some point in the year to 18x11.5's or 18x12's.
Aero:
Work in progress, but won't be on for Dixie.
Weight:
2935 w/no AC or Radio....hoping to get that below 2900 before Nationals.
Care to share anyone else?
