MAF, or AFM, etc., if so equipped. Air intake source shall be within the confines of the engine compartment or stock location. 3. b. The original, standard intake manifold shall be maintained. No porting or polishing of the manifold is permitted except as allowed by rule D.1.I these rules. c. Carbureted engines a. 1. Any carburetor jets, needles, and/or metering rods may be used in the stock or approved optional carburetor(s). Alternate needle valves are permitted. Removable jets may be replaced or resized. The number of carburetors may not be changed from standard. No venturi (including secondary or auxiliary) of any carburetor may be modified in any way. 1. 2. Certain cars have optional carburetors listed. On these cars, adaptor(s) may be used to mount the optional carburetor(s), provided the adaptor serves no performance function, i.e., plenum chamber, etc. 2. 3. External throttle linkage to the standard or optional carburetor(s) may be modified or changed. Choke mechanisms, plates, rods, and actuating cables, wires, or hoses may be removed. Method of operating the secondary throttle may not be modified. (previously D.1.a.2) 5. 4. All single carbureted cars may fit an approved optional carburetor. Approved optional carburetors are: 1 Weber 32 DGV/DGAV/DGEV 1 Weber 32/36 DGV/DGAV/DGEV 1 Weber 32/36 DFV/DFAV/DFEV 1 Weber 34 DAT/DATR/DATRA/DMTR 1 Holley-Weber 5200 Weber carburetor(s) with swaged fuel inlet fitting shall be replaced by drilling and tapping the carburetor body for a threaded fitting. Fuel injection manifold(s) shall not be replaced with carburetor manifold(s) from a different model, type, or engine size in order to fit an optional carburetor. All cars equipped with multiple carburetors shall run the original induction system, except for modifications allowed by the Authorized Modifications Sections D.1.a., and D.1.a.2., above in these rules. d. Fuel injected engines 6. 1. The engine management computer may be altered or replaced. A throttle position sensor and its wiring may be added or replaced. A MAP or MAF sensor and its wiring may be added. Other existing sensors, excluding the stock air metering device, may be substituted for equivalent units. 2. External throttle linkage to the standard or optional carburetor(s) may be modified or changed. Choke mechanisms, plates, rods, and actuating cables, wires, or hoses may be removed. Method of operating the secondary throttle may not be modified. 2. External throttle linkage may be modified or changed. Electronic control of the throttle is forbidden unless fit as stock. The method of operating any secondary throttle may not be modified. Electronically actuated throttle bodies may not be replaced by mechanical units unless specified on the vehicle’s spec line. Requests for alternate throttle bodies will be considered on a case by case basis. 6. 3. The engine management computer may be altered or replaced. A throttle position sensor and its wiring may be added or replaced. A MAP or MAF sensor and its wiring may be added. Other existing sensors, excluding the stock air metering device, may be substituted for equivalent units. 7. 4. Wires and connectors in the engine wiring harness may be modified or replaced.
It is not allowed for the ignition timing to be converted to a non-distributor conversion as it goes against the IT philosophy of remaining basically stock.
The specific models do not need to be called out specifically to include convertible models within the spec line. "Convertible model cars are permitted provided they meet 9.3.18 and 9.4 requirements."
Thank you for your letter. Your request is already covered in the GCR 9.1.3.9d. Lexan front windshield permitted with 20# weight adder. Lexan rear window permitted with 20# weight adder. Any number of Lexan side windows permitted with 5# weight adder Windshield clips and rear window straps per the GCR Section 9.3 Windshield Clips/Rear Window Straps, are permitted and recommended.
In GCR Section 9.1.3.9.F, change as follows: "Convertible soft-tops and attaching hardware shall be completely removed. Note: Convertible model cars are permitted if they were only available as convertibles (e.g. MG Midget), or if the convertible model is specifically allowed on the vehicle spec lineprov provided they meet 9.3.18 and 9.4. requirements. Convertible models may compete with their respective OEM or aftermarket hardtop that retains the OEM silhouette. Rear glass in such hardtops may be of automotive safety glass or polycarbonate material. All latches shall be replaced with positive fasteners. Manual and electric sunroofs, original or aftermarket, where the panel is not normally removable shall be retained and run in the closed position. Components (motors, cables, rails) may be removed provided the panel is securely retained. Removable sunroof or T-top may be retained if bolted or

All glass panels in the roof must be removed. Movable or removable metal or composite panels in the roof may be either removed or positively secured in the closed position. Any openings in the roof resulting from the removal of a panel must be covered with panels of stock contour made of the same material as the stock surrounding roof structure."
Thank you for your letter. The ITAC agrees that replacement glass for many of these cars is difficult if not impossible to obtain. Regardless, the Lexan does represent a weight advantage thus the weight adder.
Thank you for your letter. Yes, if we were to implement this there would be language elsewhere in the GCR that would need to be cleaned up. As it turns out, that is not necessary at this point. Please see letter #31782 in current 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

Thank you for your letter. We have submitted a tech bulletin to include the Audi A3 in ITR at 2950#. Please note that Turbo cars have only recently been allowed into Improved touring. The rules for turbo engines are very strict including stock turbo, stock intercooler and charge piping, and stock ECU calibration. Please review ITCS 9.1.3.3 Turbocharged Engines for complete regulations. Cars built to World Challenge or Continental/Koni Challenge etc. regulations will not be compliant in IT and should be fielded in STU.
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 to allow 1.6 Miatas in ITA convert to 94-01 differential
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. No one requests a "no performance advantage" item because it has no performance benefit. The CRB does not recommend this
In IT, GCR Section 9.1.3.D.3, insert the following and renumber following sections as follows: "3. Turbocharged engines (only) The following rules are specific to cars equipped from the factory with turbocharged engines and classified in the ITCS. Section D.1 applies except where there are disagreements between section D.1 and these rules (e.g Exhausts and Intakes), in which event these rules take precedence. a. The Turbo must be identical to the original stock turbo fitted from the factory. b. Exhaust system shall remain as stock from the cylinder head to the turbo outlet. Exhaust system tubing after the turbocharger may be no larger than the factory exhaust tubing. Catalytic convertors may be removed.

c. All intake tubing from the air cleaner to the turbo and from the turbo to the throttle body including any intercooler(s) must remain stock or stock replacement parts. Stock air metering device must be retained in its original location and housing. d. Engine control unit (ECU) and calibration (AKA tune or map) must remain stock, no aftermarket tuning, or alternate ECU Is permitted. Factory ECU updates such as those done in accordance with a recall or service bulletin from the vehicle manufacturer are permitted. e. A port for measuring intake manifold pressure must be provided and available for scrutineering use. This port shall be capped or plugged when on track."
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.

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."

Open IT brake calipers
#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. Please provide your feedback through crbscca.com.
