I received this through our local Rally-X Regional mailing list so I assume it's public info.
edit: It's on the public SCCA forums too.
Big ones for me are no cats required in Prepared and allowed to add a LSD in Prepared if you don't have one.
Hi All,
Below are the proposed rule changes for 2009. You can also find these on
the SCCA website Forum
http://www.sccabb.com/forum_posts.asp?TID=6590

Please either put comments on the Forum or send them to rxb@scca.com
Here are the proposed rule changes for the 2009 RallyCross rules. The RXB
appreciates the time and effort of all the members that have submitted
comments and the time that the rules committee has spent on this layer of
the rules change process.
Per the rules change timeline as posted at
<http://www.sccabb.com/forum_posts.asp?TID=6182&PN=1>
http://www.sccabb.com/forum_posts.asp?TID=6182&PN=1 , we are ahead of
schedule and now offer this draft two weeks early. We will accept member
comment on this draft intil June 15, 2008.
Please post all comments in this thread to keep discussion in one place.
Please do not use the previous threads. I am going to ask that those older
threads be closed (not deleted) so we can keep the discussion on topic with
the current proposed changes as opposed to the raw rules change requests as
submitted by the members.
Enough with the preamble, here they are!
Scoring
5.2.E The method of scoring Regional Rallycross events (all runs, dropping
one or more runs, fastest run only, etc.) shall be posted and available to
all competitors. Additionally, this information must be included in the
supplementary regulations submitted with the sanction application (Article
5.6). National and Divisional RallyCross events must use a cumulative
scoring method with no dropped runs.
Stock Category
6.2.C.2.d Tires must be the original size plus/minus 20mm cross section and
5% aspect ratio. (For example, a car that came equipped with a 205/55/16
can run cross section from 185 to 225 and aspect ratio from 50 to 60. This
also eliminates the tread gap rule.)
6.2.C.13 Shocks/dampers may be replaced with OEM or aftermarket replacement
units intended for the specific year make and model used. The stock spring
must be used as it was on the OEM unit. The spring perch must be factory
welded to the damper or use the exact attachment method and position as OEM.
Adjustable dampers are only allowed if the OEM unit was adjustable and must
retain the same number of adjustments or fewer as OEM. Remote reservoir
shocks are only allowed if they are exact OEM units. (The change is adding
"and position" to the third sentence)
6.2.C.14 The front sway bar may be replaced or removed. A replacement front
sway bar may serve no other purpose than originally intended by the vehicle
manufacturer. In the case where the front sway bar is also a suspension
locating link, stock geometry and methods of attachment must be maintained.
Prepared Category
Delete 6.2.D.4.d in it's entirety. (This allows prepared category vehicles
to remove exhaust catalysts)
6.2.D.14 On carburetor equipped cars, jets, accelerator pumps, power valves,
metering rods, vacuum secondary and metering springs may be replaced.
Removal of choke plates, linkage and shafts is allowed. No machining
allowed of any carb component.
6.2.D.15 Vehicles may substitute one differential with a mechanically
governed limited slip or locking unit of an alternate type. This includes
spools and welded stock differentials. This does not allow the use of a
differential with external controls (electronic or otherwise) to regulate
slip or locking. Differentials must be contained in a stock unmodified
housing/third member with stock or optional ring and pinion ratios available
for the specific model, body, and year of the vehicle only. 4wd vehicles may
not substitute more than one differential with an alternate type.
6.2.D.16 Batteries may be substituted with any type. Relocation of the
battery or batteries within the engine compartment or trunk area/luggage
compartment behind the rearmost seats is permitted. Longer battery cables
may be substituted to permit relocation and holes may be drilled to
accommodate mounting of the battery and cables.
6.2.D.17 Accessory drive pulleys and belts may be replaced.
Modified Category
6.2.E.6 Side and rear windows may be removed or replaced with Lexan or
equivalent. Windshield may be replaced with Lexan or equivalent with
addition of a full roll cage built to SCCA Improved Touring specifications
or better.
6.2.E.10 The shape of the body must remain recognizable as that of the
manufacturer's make and model. The body must be made of a fire resistant
material. Doors, hoods, trunk lids, sunroofs, hatchbacks, etc. need not
function as originally designed. Bumpers, grilles, lights, glass, and trim
may be removed. Side mirrors and tail/stop lights are not required. Any
edges created by these modifications that the driver or passenger may
contact must be properly insulated to prevent injury. Roof panels must be
metal of at least the same thickness as original. Sunroof panels may be
replaced with sheet metal of at least the same thickness as an original roof
skin without sunroof. Inner roof structure may only be modified with
addition of a full roll cage built to SCCA Improved Touring specifications
or better.
6.2.E.14 - Any fuel system may be used provided gasoline or diesel fuel is
used. Any NON-STOCK fuel cell, filter or pump located in the passenger
compartment must be shielded by a metal bulkhead. Any fuel lines running
through the passenger compartment must be of metal or metal braided
construction.
Changes NOT recommended at this time.
Stock
6.2.C.13; Allow double adjustable dampers. Not recommended based on cost
and class philosophy
6.2.C.15 - Paint is free. Graphics may be added. Not recommended as this is
already covered by 6.2.C.5 .
Prepared
6.2.D.14 - Fasteners are free. Not recommended as this is covered by 6.2.B.
