WMCA Road Racing Classing Review – Preliminary Report
Authors: Doug Campbell and Gary Roberts
Rationale
Over the past several years the WCMA has received numerous comments regarding the current classing structure both at AGMs and via E-mail. During this time the WCMA has made changes both small and large to the rules, with little effect on the content or number of comments. Key concerns raised include;
Lack of inclusiveness
• Certain makes and models require a minimum weight not conducive to racing
• Certain “common” modifications are not allowed or permitted in “Entry Level” Classes
Do not reflect the current state of motorsports
• GT Displacements
• “Tuner Mod’s” are not permitted in “Entry Level” classes
Ability of members to travel or to attract racers from other areas.
• Majority of class do not match any neighbouring regions
Lack of competiveness
• Classes allow too great of a disparity between cars to create competition.
• Too many Classes
While these concerns come with varying degrees of accuracy, it has been many years since the WMCA last did a ground up review of the rules and not just adapted or modified our existing rules.
Mandate
Review current classing rules from all neighboring regions to determine if there is an existing rules set that will meet the need of the WCMA and its members, and could be a suitable replacement of any combination, or all of IT, ST and/or GT.
Criteria
The following criteria will be used to help formulate a recommendation;
• Must be more inclusive
• Should not exclude any current competitors
• Must align with areas that members could visit, or other racers could visit from.
• Must maintain some level of affordability
• Should be well suited to address the issues of Modern Cars and Modifications
• Must maintain or reduce the number classes
• Must offer a reasonable competitive balance within classes
• Must be viable as a long term solution.
Summary of Rules Reviewed
CACC-BC (British Columbia): GT, GTS and IP.
http://www.caccautosport.org/wp-content/uploads/2013/02/2013-Race-Regs-Final.pdfCACC-BC runs a rule set with an approach somewhat similar to the WCMA. They Run SCCA GT1,2,3, and L with 3 classes or GTS “catch-alls” (<2.0L, 2-4L and >4.0L). IP cars must meet SCCA IT prep rules, however they are reclassified by displacement (IP3 >1750CC and SM, IP2 1750-2750CC and Pro-3m, IP-1 >2750 CC and ITE, a “catch-all” that allows some additional modification not permitted in other IT classes) and min weight is Manufacturer curb weight – 100lb.
A transition to the CACC-BC rules may be easy, however, they do not meet many of the key criteria, including being more inclusive and not excluding current competitors, and offer little to no upside to the current WCMA classes.
CASC-OR (Ontario): GT
http://www.casc.on.ca/sites/default/files/casc_2014_qf_gt.pdfCASC-OR runs a GT1-6 for sprint races where type of vehicle and level of modification is not a factor in classing. Car classing is a bracket system based solely on lap time; each track has its own lap time for each class, and it is possible to be in a differently class at each track.
This does create classes that run very similar lap times, and is very inclusive, but it does not truly create a competitive balance and is not in the spirit of racing in the WCMA.
CASC-OR (Ontario): GT Challenge
http://www.casc.on.ca/sites/default/files/casc_2014_qg_gtc.pdfFor endurance races the CASC-OR runs “GT Challenge” with Classes of GT, GS, ST1, ST2, ST3 where classes are based solely on power to weight, with no adjustments due to differences in chassis or driveline layout. Classing is wide open with a few exceptions. The rules appear to be more, a set of supplemental regulations for endurance racing, than a complete classing structure.
These classes do again offer a very inclusive structure, with little to no limitations on what can be run. Using solely power to weight does put affordability at risk as all other areas of modification are fully open. Also included in this review are other rules are primarily based on power to weight but are more complete.
ICSSC (Conference): – Multiple
http://www.icscc.com/references/comp_regs_2013_complete.pdfICSSC runs many classes, almost all SCCA or catch all’s based on these classes. In some cases confusingly, these classes are listed both as individual classes and rolled up into one catch all (Example rule 1307: “Improved Touring A (ITA), Improved Touring B (ITB), Improved Touring C (ITC), Improved Touring S (ITS). These classes shall run under current year SCCA rules“ and rule 1325: “ITX This class shall run under current ITA, ITB, ITC, & ITS SCCA rules. (Fall 2011)”). There are some Spec classes but they are not included in this review at this time.
ICSSC would offer a nearly unlimited number of classes to pick and choose from, however there is no reason not to go directly to the SCCA for the classes, and the catches all’s do not eliminate any of the WCMA’s issues.
SCCA (Sports Car Club of America): - GT, ST, and IT
http://scca.cdn.racersites.com/prod/assets/2014%20GCR%20February-mobile1.pdfThe WCMA’s current classing structure is largely based on the SCCA’s GT, ST, and IT rules, on allowed modifications, and members of the WCMA should find the SCCA rules fairly familiar. The WMCA has not always followed the SCCA’s updates, which have led to some differences, most notably the Single Inlet Restrictor rules in GT. The current issues related to inclusiveness in the WCMA are largely related to the SCCA rules on allowed modifications. The SCCA also has other classes, but most of those are targeted to a specific car or group of cars.
Following the SCCA rules exactly should level the competitive playing field, however without adding more classes, it would only compound the WCMA’s current issue with inclusiveness, and exclude some current competitors, and force GT cars to move to SIR’s.
NASA (National Auto Sport Association): – PT and ST (Performance Touring and Super Touring)
http://www.nasaproracing.com/rules/performance_touring_rules.pdfhttp://www.nasaproracing.com/rules/Super-Touring.pdfNASA’s PT and ST classes are designed to work together where, if desired, a competitor can progress their car slowly up through PT into ST.
PT (PTB-F) works by starting cars off in a base class with some “free” modifications, and allowing other modifications by claiming points which, as they are accumulated, move cars up to a higher PT class and eventually into ST classes. This points system, while a little complex, does allow cars to run with a wide variety of modifications, and ensures all cars can have a home in PT. NASA has as minimum adjusted Power to weight for each class to help ensure competitive balance.
ST (ST1, ST2, ST3 and SU) classes are based power to weight ratios (higher then PT) with some adjustment. ST1-3 cars can maintain a relatively stock chassis (Frame rails, Floor pan, etc), or with an adjustment to the power to weight chassis can be modified or a full tube frame, SU is a truly unlimited class (excluding safety)
PT Example - 92-95 stock (less safety equipment) Civic weighing 2390lb on RA-1’s is in PTF, but if that same car was to upgrade Swaybars , header, exhaust, remove the cat, and add coilovers and run A6’s, it would be in PTE.
Like the SCCA, NASA also offers many other classes targeted to one car or one group of cars. (eg: Spec BMW E30 and German Touring Series) We would not recommend adopting these other classes unless competitor numbers were sufficient.
Conclusion
While some regions rule sets offer a solution to some of the WCMA’s concerns. NASA with PT and ST is the only one to offer a suitable alterative to the current WMCA IT, ST, and GT classes that meets 100% of the criteria.
• Must be more inclusive
o Every car regardless of modification has a place to race.
• Should not exclude any current competitors
o All WCMA IT and many ST cars will find a competitive home in PT, and the balance in ST. All GT cars should find the same in ST.
• Must align with area that members could visit, or other racers could visit from.
o NASA runs races across the US including the NE. NASA cars should also be able to run in the CASC-OR and ICSSC, and, any CACC-BC, CASC-OR, ICSSC, or SCCA could run in the WCMA
• Must maintain some level of affordability
o PT maintains entry level affordability and allows development of the car over time.
• Should be well suited to address the issues of Modern Cars and Modifications
o Both PT and ST allow modern cars and modifications.
• Must maintain or reduce the number classes
o The number of classes is reduced from 11 to 9
• Must offer a reasonable competitive balance within classes
o Statistically, the large number of cars and competitors running NASA rules, ensures a reasonable calculation of competitive balance within classes
• Must be viable as a long term solution.
o NASA is a strong organization that regularly updates and maintains their rules. There is no reason to expect this to change in the near future, and that these rules should be viable for years to come.
Recommendation
That the WCMA replace IT, ST and GT class rules with a reference to NASA’s PT and ST in the same format, as we have done with Spec Miata, for the 2015 Race Season.
Next Steps
1) That the WCMA publicly announce this review and its’ conclusion, to all members and competitors via the Web forums.
2) Provide a period for members and competitors to provide written comments or concerns for review and consideration. This period should be not less than 6 weeks but should be completed no later than May 1st
3) The WCMA Tech committee (lead by Gary Roberts and Doug Campbell) to review all submissions for consideration, and review. This period should be not less than 6 weeks or more than 8 but should be completed no later than July 1st
4) Gary Roberts and Doug Campbell to submit a final recommendation to the WCMA upon completion of the review within 2-4 weeks (Based on the outcome of the review, the final recommendation will recommend the immediate announcement of change to the rules for 2015, or if after the submissions and input of the tech committee, a clear conclusion could not be reached, the announcement of PENDING change in the rules for 2015, to be finalized at the AGM)
5) That the WCMA publicly announce the final review and its’ conclusion
