Rules Addendums and Clarifications

Technical Bulletins:

___________________________________________
Technical Bulletin 1-21-10

All Vehicles--Strut tower top modification for simple
camber/caster adjustment:

No-Points Modifications
10) Simple camber, caster, and toe adjustment by any method that
does not alter suspension mounting points (unless the modification
used is otherwise assessed points above--such as control arm, ball joint,
and relocated mounting point modifications). Slotting of the OEM bolt
holes and removal of material from the top surface of the OEM strut/
shock tower to the extent necessary to allow simple camber/caster
adjustment is permitted. Bolt on camber/caster plates are not assessed
points.

Technical Bulletin 1-21-10

All Vehicles--Spindle/Knuckle modification or replacement
for hub size change:

No-Points Modifications
8) Wheels, wheel studs, wheel bearings replacement/upgrade, hub
modification/replacement, axle modification or replacement (unless
otherwise assessed points above). Spindles/Steering Knuckles may
be modified or replaced as a No-Points modification to allow for hub
size change provided that there are no changes in suspension
geometry or mounting point locations (such as tie rod connection
height, ball joint connection location/height, etc.)

CLARIFICATIONS:
Here are some clarifications that have been made by NASA TT
Administration when competitors have had questions about the
rules. These clarifications qualify as "Technical Bulletins" under
section 6.1 of the rules, and should be treated as if they were
written directly into the rules.

Clarification--Engine Blocks: Aftermarket engine blocks made by
companies other than your car's original manufacturer, or those
made by your manufacturer, but that are not identical to your
original equipment constitute an ENGINE SWAP. It doesn't matter
if they are the same displacement as OEM. All engine swaps
need to be assessed by the Regional and National TT Director
on an individual basis. These blocks allow for a much more
"aggressive" modified rebuild due to their higher cylinder wall
strenth, yet the rebuild would otherwise cost the same number
of points as someone with the same size block that could not be
as aggressive. We will charge you points accordingly, depending
on the situation.

Clarification--Rear Suspension Upgrades: The combination of
a panhard rod addition, torque arm addition, and changing from
a 4-link to 3-link rear end suspension will be assessed +4, +4,
+6 (for relocated rear suspension mounting points), for a total
of +14 points.
