2009 SCCA Solo rules now allow big brakes (i.e. 13" cobras), alternate engine mounts, and other stuff in Street Prepared:
"MOTION: To accept the 2009 Solo Rules changes as submitted by the Solo Events Board.(Noble/Introne) PASSED, Unanimous
STREET PREPARED CATEGORY
ITEM 19) Replace 15.2.F with:
“The driver and front passenger seats may be replaced, with the following restrictions: Seats must be securely mounted per
3.3.3.B.2. The seating surface must be fully upholstered. Any replacement seat must be a full back, bucket type automobile
seat incorporating a functional headrest. Kart seats & low back dune buggy seats and other similar types of seat are
expressly prohibited. Cars may have no fewer than the standard number of seats. The seat tracks are considered part of the
seat and may be substituted. Alternate seat tracks may serve no other purpose. The standard seat belts may be removed to
facilitate the installation of alternate restraints complying with safety requirements.”

ITEM 20) Change 15.2.H to read:
“Airbags may be electronically disabled but not removed.”
SCCA Fastrack News June 2008
ITEM 21) Replace 15.6 BRAKES with the following:
“Vehicles may only exceed the allowances of 13.6 as specified herein.
A. Any brake line, single or dual master cylinder, vacuum brake booster, or brake proportioning valves may be used.
This does not allow multiple separate cylinders, but does allow for any single, dual-circuit cylinder.
B. “Safety brakers” and units such as the “Brake Guard System” are permitted.
C. ABS braking systems may be disabled, but not removed; brake boosters may be removed, modified, substituted, or
added.
D. Alternate brake rotors are permitted, subject to the following restrictions:
1. Rotors must be ferrous metal except for standard parts. Aluminum rotor hats are allowed. Rotor dimensions
(diameter and thickness) must be equal to or greater than standard parts. Cars originally equipped with solid
(non-vented) rotors may utilize vented rotors.
2. Cross-drilled and/or slotted brake rotors may be used. Slots/holes are permitted only in the braking area
of the rotor. Rotors featuring a drum-type parking brake in the hat area of the rotor may not be drilled or slotted in
the parking brake area.
E. Drum brakes may be replaced with disc brakes. Disc brake rotors for such a conversion must be equal to or greater
in diameter than the inside diameter of the standard brake drum. Changes to backing plates/mounting
brackets/brake lines to accommodate this change are permitted but may serve no other purpose. Drum-to-disc
SCCA Fastrack News July 2008 Page 5
brake conversions must be bolted, not welded to the axle/control arm/upright.
F. Air ducts may be fitted to the brakes, provided that no changes are made in the body/structure for their use. They
may serve no other purpose. Backing plates and dirt shields may be modified or removed.
G. A functional, redundant emergency (parking) brake must be present.
H. Brake calipers may be replaced, provided the number of pistons is equal to or greater than the original number of
pistons. Caliper mounting brackets may be replaced to accommodate this change, but may serve no other purpose.
Alternate caliper brackets must bolt to the original caliper bracket mounting location(s).”
SCCA Fastrack News July 2008
ITEM 22) Add new section after 15.10.G:
“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.”

ITEM 23) Change 15.10.J to read:
“Engine mounts may be replaced, but must attach in the factory location(s) without additional modification or changes.
Engine position may not be changed. Hydraulic shock type rear engine locators, or bobble struts may be replaced by manufacturer’s
performance part or aftermarket replacement part. This part must retain factory dimensions and attachment
points, including factory design. (Example: If factory locator/bobble strut is gas or hydraulic piston type, replacement part
must be gas or hydraulic piston type.)”

ITEM 24) Insert after 15.10.K:
“Engine cooling radiators may be replaced with alternate parts subject to the following restrictions:
1) Radiator core dimensions (width, height, thickness) must be no smaller than the standard part.
2) Radiator must mount to OE radiator mounts.
3) Fluid capacity /_and dry weight_/ of radiator must be no less than that of the standard part. Alternate
radiators may serve no other purpose (e.g. to allow a cold air intake passage).”
