suggest STU as a candidate. Also, most regions do have regional only catch all type classes that we are sure the cars would be
welcomed.

Opposed to 200tw Tires

#31782 from Steve Elicati · No action required · Minutes (2022-03 Fastrack)

Thank you for your letter. And we mean that sincerely!
This issue has generated more member feedback than anything in recent memory. Some excellent points have been made both
for and against the change, and they have been noted. At the moment there really is no clear answer on which path is best.
The Committee has agreed that some of the issues that have been raised require additional research and discussion before we
can move forward. That work has already begun.
Possibly for that reason, although likely there were other considerations as well, the Competition Board has decided NOT to
move forward with the 200TW tire rule for Improved Touring at this time.
We certainly believe everyone involved, particularly all of you that felt strongly enough to reach out about this, ultimately have

the best interests of Improved Touring in mind. We are coming up on a very significant IT anniversary, and hopefully we can
celebrate it with larger car counts at events across the country.
Please don’t hesitate to continue to tell us what’s on your mind. We really are all in this together. Your ideas, support and even
thoughtful disagreement will help to keep us pointed in the right direction.

Alternate Miata Hubs

#30053 from Michael Kamalian · Not recommended · Minutes (2021-02 Fastrack)

Thank you for your letter. Your request is not within the philosophy of the rules. Aftermarket produced parts are allowed per the
rules provided they are direct replacement parts designed with exactly the same dimensions, type of internal parts, etc. as the
OEM part they replace.

Request adding 7.5

#29582 from Corry Hunter · Not recommended · Minutes (2021-02 Fastrack)

Thank you for your letter. Under GCR 9.1.3.7, IT wheel and Tire rules. Wheel sizes listed are maximum sizes with their
corresponding maximum section width. In ITS a 7.5" wheel is already permitted and would fall under the 8" maximum rim width
with a maximum section width of 225. The purpose of the regulation is to limit the advantage of a wider wheel. We do not
recommend a change to this regulation at this time.

Request for E30 325i Weight Reduction

#29122 from Skylar McKnight · Not recommended · Minutes (2021-02 Fastrack)

this car relative to others in ITS and make a correction in the future if needed.

Request to allow 1.6 Miatas in ITA convert to 94-01 differential

#28983 from Ron Munnerlyn · Not recommended · Minutes (2020-12 Fastrack)

Thank you for your letter. Your request is not within the class philosophy. IT does not allow modification or replacement of
major components of the vehicle such as the differential carrier /rear end. Differentials are available that fit the 1.6L NA Miata's
(e.g. Kaaz, OS Giken), where many cars classed in IT must resort to modified OEM or very rare and hard to find differentials. This
is part of the "warts and all" philosophy that keeps the IT rules simple and limited. Allowing such a modification opens the door
to similar such changes across the range of IT classifications and potentially cascading requests for other cross-platform bolt-
ons. That is unwanted, the change is inconsistent with the class philosophy, and the justification for the change isn't even a real
problem for the car.

Request for vehicle Classification

#28819 from John Budrevic · No action required · Minutes (2020-12 Fastrack)

Thank you for your letter. ITE is a regional class operated under a number of rule sets at regional levels, not a national one
controlled by the ITCS. This car is certainly a candidate for catchall rules like ITE, SPO, etc., however does not fit the IT philosophy
or performance envelopes.
The Author is in Gainesville, FL, putting him in the SEDIV. Rules for their club racing regional classes can be found on the
divisional website sedivracing.com. SEDIV offers SPO for turbocharged cars like this one but it would not meet the safety
requirements of production or GT that the category requires. The direct link is as follows:

Remove Verbiage about an Assessment Clock in 9.1.3.C.

#28610 from Improved Touring Committee · Recommended to the Board · Minutes (2019-05 Fastrack)

In Improved Touring, GCR section 9.1.3.C, change as follows:
"During the initial vehicle classification process, the Club shall assess vehicle performance factors such as
– but not limited to – manufacturer’s published specifications for engine type, displacement,
horsepower, and torque; vehicle weight; brake type and size; suspension design; and aerodynamic
efficiency. Based only on such clearly measurable physical factors, a minimum allowable weight shall be
established. At the end of the second, third, and fourth full years of classification, the vehicle’s racing
performance relative to other vehicles in its class shall may be evaluated. If the Club deems that, in the
interest of fostering greater equity within a class, a vehicle should be reclassified to another Improved

Touring class, such a reclassification may be made. Alternatively or additionally, if the Club deems that
an upward or downward revision in the minimum allowable weight is warranted, such an adjustment
may be made. At the end of a vehicle’s fourth full year of Improved Touring classification, the vehicle’s
minimum weight shall be established. Cars with weights assigned prior to 1/1/2005 may have their
weights reassigned using the same process that is used for new listings. Should this occur, the
assessment clock will start anew. Racing history of this particular model may be considered at this time
and an adjustment may be included in the new minimum weight, and the adjustment may be
reconsidered at the end of any of the first four full years of competition. If at any time an error is
discovered in the physical factors used to assess a vehicle’s weight or an error was made during the
application of the weight-assignment process, the error may be corrected. Should such an error
correction occur, the assessment clock will start anew. Racing history of this particular model may be
considered at this time and a performance compensation adjustment may be included in the new
minimum weight, and the racing history of this model may be evaluated for an adjustment at the end of
any of the first four full years of competition after the correction is made. On rare occasion—and only
after careful review of the actual racing performance of a particular make/model/ year of vehicle—the
Club may reclassify a vehicle, revise a vehicle’s minimum allowable weight, and/or in the most extreme
situation an intake restrictor may be required. Such an action shall be taken solely for the purpose of
restoring equity within the vehicle’s class."

#25828 from Improved Touring Committee · Member feedback requested · Minutes (2019-01 Fastrack)

The CRB is seeking your feedback on the following:
Allow any brake caliper up to 4 pistons to be used on any car in the ITCS. Brake master
cylinder and rotors would remain stock.
This is to take advantage of the availability and relatively low cost of pads as well as address
stock component shortages without introducing a significant change to the balance of
competition.
