no not yet, but did anyone see this that was just posted on score's website:


"2006-2010 SCORE INTERNATIONAL TECHNICAL RULE BOOK



The following are some, but not all of the new rules in the 2006-2010 SCORE International Rule & Regulations book. The new and complete 2006-2010 will be available soon. These rules will take effect on April 1, 2006.



GDC1 Classes 1/2-1600 (Single Seat), 9 (Single Seat), 10 (Single Seat), Score Lites (Single seat), 21, 22, 30, 40, 50, 24, and 25 may only compete with one (1) driver/rider during competition.

Classes 1/2-1600 (Two Seat), 5-1600, 9 (Two Seat), 10 (Two Seat), Score Lites (Two seat), 11, Stock Mini, Stock Full, and Protruck must always compete with one driver and one co-driver during competition.

Classes Trophy Truck, 1, 3, 5, 6, 7, 7S, 7SX, and 8 may compete with one driver or one driver and one co-driver during competition.

Driver/rider and/or co-driver changes are permitted in all classes as long as the driver/rider and/or co-driver is a banded driver on that vehicle entry.

NO VEHICLE WILL BE ALLOWED MORE THAN TWO OCCUPANTS AT ANY TIME.



GT11 All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.



All vehicles built before January 1, 2006 may be required to have an inspection every six months.



CR1 HELMETS

Helmets used in four-wheel vehicles must meet the following requirements; Snell memorial foundation, SA2000 or SA2005, with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached. Motorcycle and ATV’s must meet the following requirements; Snell memorial foundation, M2000 or M2005, with a legible Snell sticker attached, FIA Standard 8860-2004, with a legible FIA sticker attached, or BSI 6658 Type A. SCORE recommends each helmet be labeled (painted) with the driver/riders name, blood type, allergies, or any other medical information. Straps must have "D" rings, no snaps.



CR33 ROLL CAGES

All vehicles in competition except Motorcycles and ATV’s

must be equipped with a roll cage. Minimum design and tubing

size based on seamless 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM.

No aluminum or other non-ferrous material permitted.



Material

Material for roll cage construction must be 4130 chromoly tubing or ASTM 1018/1026 CDS/DOM.

All welding must be of the highest quality with full penetration and no undercutting of the parent metal. All welds shall conform to the

American Welding Society D1.1, Structural Welding Code, Chapter 10, Tubular Structures and Standards for the material used (see AWS. Org). It is strongly recommended that the welder inspect all welds using Magnaflux™, die-penetrate, or other effective methods.

All tubes must be welded 360-degrees around the circumference of the tube.

No oxy-acetylene brazing or welding allowed. Good external appearance of a weld does not necessarily guarantee its quality, poor looking welds are never a sign of good workmanship.

None of the tubing may show any signs of crimping or wall failure. All bends must be mandrel type. The center radius of the bends may not be less than three (3) times the outside diameter of the roll cage tubing.

It must be emphasized that the use of heat-treated or high carbon steels may cause problems and that bad fabrication may result in a decrease in strength (caused by brittle heat-affected zones), inadequate ductility and internal stress.



Roll Cage Tubing Sizes

For the purposes of determining roll bar tubing sizes, vehicle weight is as raced, but without fuel and driver. Note: There is an allowance of minus 0.010 inches on all tubing thicknesses. Minimum tubing size for the roll cage is:

Up to 2000 lbs.

1.500” x 0.095” CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM

2001 - 2500 lbs.

1.500” x 0.120” CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM

2501 - 3000 lbs.

1.750” x 0.095” CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM

3001 - 4000 lbs.

1.750” x .120” CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM

Over 4000 lbs.

2.000” x 0.120” CDN/4130/Seamless or ASTM 1018/1026 CDS/DOM





Construction Procedures

Cages must be securely mounted to the frame or body and

gusseted and braced at all points of intersection. Cab or body

mounted cages must not be attached to the body structure by

direct welding, but must be bolted through and attached by the

use of doubler plates (one on either side) with a minimum thickness

of .187”, see Figure 4. Where bolt and nuts are used the

bolts shall be at least .375” diameter SAE Grade 8 or equivalent.

Roll cage terminal ends must be located to a frame or body

structure that will support maximum impact and not shear.

Minimum material dimension requirements for roll cages apply to

the following members of the roll cage:

(1) Front and rear hoop

(2) Front and rear interconnecting bars

(3) Rear down braces

(4) Lateral bracing

(5) Elbow and door bars

(6) Lower A-pillar tubes, and lower B-pillar tubes







Roll Cage Design

All roll cages must be constructed with at least one (1) front

hoop (top of cage to floor), one (1) rear hoop (top of cage to floor), or two (2) lateral hoops, two (2) interconnecting top bars, two (2) rear down braces and one (1) diagonal brace and necessary gussets, see Figure 1. If front and/or rear hoop terminate at elbow/door bar, lower A-pillar and/or B-pillar must be made of same tubing size as roll cage. Upper main, front, rear, and lateral rollbar hoops must be made in one piece without joints. Centerlines of all required tubes must converge at intersections.

Any vehicle that is not provided with stock steel doors for its driver and co-driver must be equipped with sidebars, at least one on each side that will protect the occupants from the side. These bars must be parallel to the ground (or as close to parallel as is practical) and be located vertically in relation to the occupants to provide maximum protection without causing undue difficulty in entering or exiting the vehicle. The sidebars must be formed of tubing of the same material and dimensions as the roll cage itself and must be securely attached to the cage’s front and rear members. Additional side tubes may be required to limit cockpit intrusion, these additional tubes must be of the same size tubing as the roll cage. Tubes must be placed in such a manner as to limit openings adjacent to the occupants. Maximum opening size in this area is limited to 370 square inches.

All roll cage bars must be at least 3” in any direction from the driver and co-driver’s helmets while they are in their normal driving positions.

Gussets must be installed at all main intersections on the main cage including diagonal and rear down braces, and where single weld fractures can affect driver’s safety. Gussets may be constructed of .125” X 3” X 3” flat plate, split, formed and welded corner tubing, or tubing gussets the same thickness as the main cage material, see Figure 2 and Figure 3. Rear down braces and diagonal braces must angle no less than 30 degrees from vertical.

An inspection hole of at least .187” diameter must be drilled in a non-critical area of the roll bar hoop to facilitate verification of wall thickness. It is the prerogative of SCORE to drill a second hole if deemed necessary.

Any cage or chassis that has been built after January 1, 2006 must be identified by means of an identification plate affixed to it by the manufacturer; this identification plate must be neither copied nor moved (i.e. embedded, engraved or self destroying sticker). The identification plate must bear the name of the manufacturer, a serial number, and the date of manufacturer.

Head/neck restraints designed to prevent whiplash are required on all vehicles. These restraints must be a headrest of approximately 36 square inches, with a resilient padding at least 2” thick. Any portion of the roll bar or bracing which might come in contact with the helmet must be padded.



Roll Cage and Vehicle annual inspection

All vehicles must have their cages approved prior to racing in a score event. The inspection will be preformed at the Score Technical office. After passing inspection and paying Inspection fees all vehicles will receive a Score I.D. tag, that is to remain with the vehicle at all times. If tag is removed or lost vehicle must be re-inspected and retagged. Any modification to an approved cage may render its approval invalid, and may need to be re-approved. All repairs to a roll cage damaged after an accident must be re-approved by SCORE International.



All vehicles built before January 1, 2006 may be required to have an inspection every six months.

no not yet, but did anyone see this that was just posted on score's website:


CLASS 11





Rear Suspension


Rear shock tower may be removed to body mounting bolthole. Lower rear shock mounts may be removed and or replaced. Rear shocks may be relocated, but must bolt directly to rear trailing arm or swing axle. No remote mounted shocks.

CR10 SHOCK ABSORBERS and BUMP STOPS

Only one shock per wheel is allowed. Stock shock mounts must be utilized. Shock mounting bolts may be changed to a maximum of 0.5" in diameter. Any manufacture shock allowed with 2.5" maximum outside diameter. Cooling fins and/or reservoirs allowed. No air shocks or coil over shocks are allowed. No hydraulic bump stops allowed. No bypass shocks allowed.


--------------------------------------------------------------------------------

Sounds to me like a little contradiction here? At the top for class eleven it says that you can remove the rear shock mount to the body mounting bolt only. and then in the shock absorbers and bump stop portion it says that stock shock mounts must be utilized? What it that all about?

[Fourstroker]

Looks like no more 2 seaters with 1 driver for Laughlin...and some other peculiar stuff. The one that stuck out was the SA rated helmets. Better start getting the new one if you don't already have one.

I didn't see anything about laughlin. looks like 2 people max in any vehicle, any race.

[bajafox]

I didn't see anything about amber lights placement or requirements. I thought that was another issue at Laughlin?

I always thought the 2 seat thing was a requirement, I was definetely surprised to see a few 2 seaters in Laughlin with only a driver.

[mccallumracing]

what does this mean for a 3 seat trophy truck?

[SanoDano]

"NO VEHICLE WILL BE ALLOWED MORE THAN TWO OCCUPANTS AT ANY TIME."



No doubt to address the problems from Laughlin with the four seaters racing.

[Tom_Willis]

GDC1 Classes 1/2-1600...), 21, 22, 30, 40, 50, 24, and 25 may only compete with one (1) driver/rider during competition.



--------------------------------------------------------------------------------

I don't recall seeing two riders on a bike or quad, either.

[stuckthrottle]

CR23 ENGINE and ENGINE DISPLACEMENT

Any two-stroke engine displacing 250cc or less or any four-stroke displacing 450cc or less may be used."

Sucks for the 2 stroke guys. 450 4 strokes should be racing open class. Just look at the hp figures.
