We have posted the revised PT rules, version 1.6, on the NASA website (with links on the PT website and here).
http://www.nasaproracing.com/rules/Performance-Touring-rules.pdf
We also have new PT Car Classification Forms. http://www.nasaproracing.com/rules/Performance-Touring-classification-form.pdf

We took all of the rules revisions, provisional car classifications, and approved engine swaps that are "scattered" on the forums and on the PT website, and we have incorporated them into this single set of rules, with a Car Classification Form that corresponds exactly to the rules, and a PT Classer calculator on the website that has been updated to match as well. So, please use these new forms for future events and the Championships.

All of the changes/additions that have been made from the original PT Rules are shown in red type to aide in easy recognition. We've have also added the new NASA logo. There are a few minor changes as well. But, they are simple, and are really to help prevent problems, especially at the Championships--and shouldn't cause any. They are in-line with the TT Rules revisions made in April to continue to pollinate crossover from TT to racing. I'll list them here to make things easy.

Any changes to base classifications, rules revisions or additions, and Technical Bulletins will be released on the Performance Touring website http://performancetouring.com. 

...or has greater than 500 awhp for AWD vehicles, or 560 rwhp/fwhp for non-AWD vehicles, based on chassis dynamometer testing. This took the place of the 650 hp flywheel limit for cars jumping to SU--just now we are able to inspect it at the track.

Any monotube, gas-charged race shocks with aluminum body construction, removable body caps, a replacement shaft, or adjustment of any nature (preload or bleed) through the shaft; or, any shocks with an external reservoir or more than two ranges of adjustment. Also, any shocks/Coilovers with a retail price of greater than $750 each +12 (springs and perches are open--0 pts.) Ok, if shocks or coilovers cost more than $750 each ($3000 for the set of 4), then we consider them to be +12 race shocks, regardless of whether they are aluminum or not.

Add, replace, or modify camber plates or bolts, shims, steering knuckles, or struts for simple camber and/or caster adjustment only (ex. slotting of single knuckle or strut bolt hole) +2  Shims were added for points assessment.  The caster wording was added, because without it, there could have been a potential protest that caster adjustment wasn't legal since it isn't stated to be legal or free.

Add panhard rod or Watts link (regardless of whether the Watt’s link replaces an OEM panhard rod or not) +4 This was just housekeeping on the original intent of the rule.

Metallic or mixed metallic and non-metallic replacement suspension bushings (except for sway bar end links and pillow ball camber plate joints already assessed points in 9) and/or 10) above) +3 We never intended that camber plates with pillow ball joints would cost 5 points (+2 for the plates and +3 for the metallic bushings). This frees up the pillow ball joints on camber plates.

Non-OEM replacement driver and/or front passenger seat This has been in the TT rules (free with a cage), and is housekeeping to put this on the Freebie list in PT.

Base classifications are for the standard base model (base trim package) of a vehicle, without factory options of upgrades, For some reason, some people didn't realize that a base model of a car means the base trim package--so we added the wording to help with clarity. 

Enjoy the rest of the season and the Championships.
