The majority of the changes in this revision are in base class model groups. There were many changes for the '07 models, and we added a lot of new model groups. Please review the table to make sure that nothing changed for your car. There were a few changes to curb weights and classes of older cars that have been previously discussed on the forum. But, there have been a few changes, also, for some later models that needed to be separated from the older models, and grouped with the '07's. All changes are in red print.

This is a summary of the other items addressed in this revision (also in red print). Most of these items have already been discussed on the forums. All issues were brought out during forum discussions or e-mails from competitors requesting clarifications of modifications:

Weight Reduction--
no substantial change, just a few words to better clarify when the alternate weight method must be used. "or lightening of" and "or not otherwise assessed points" added
Engine Drivetrain--
11) Dry sump with motor lowering changed to +14 (from +15)
16) Air intake modification--"intercooler" piping and "hood air inlet(s)" mods added to the list
38) "Relocation of engine/transmission within 10 inches of OEM location +7" added
Aerodynamics--
3) and 4) "(top surface/tab) height" added to clarify measurement of wing height.
11) "Add vortex generator to roof, rear window, or rear deck +1" added
No Points Modifications--
11) "ratio" added to "Final drive ratio modification"
26) "unmodified" added to gasoline description
26) "Fuel additives are prohibited" added
43) "Seam welding of the body/chassis" added
44) "Shock tower reinforcement plate (to strengthen tower shock mount location only--no bars)" added
445 "Shock mount replacement/modification (only if already taking points for both shocks and springs)(may raise or lower mount location up to two (2) inches if no horizontal movement)" added

This should do it for the '07 Rules. Any future issues will be listed here on this website and on the NASA PT Forum website http://www.nasaforums.com/viewforum.php?f=16
Have a great season!
