IMS Pit Entry and Parking

In 2020, the pit paddock, finish line, and pit in/out are moving to the area just east of the Tower Terrace Suites (where the USAC .25 Midgets raced in previous years). This move will allow us more pit area on better surfaces, better facilities and infrastructure, better concessions options, and allow the Finish line to be in sight of the paddock.

ALL KART PITS MUST HAVE A TARP UNDER THE KART WORK AREA!

The starting line will still be in the same spot as it has been since 2017. This timing line is a much safer spot to start races from than the new finish line on 7th Street. So much like the Mid-Ohio Sports Car Complex does for Indycar, our starts and finishes will be at two separate spots! Qualifying will still use the same start/finish line for timing as it has since 2017.

Since the paddock is moving, pit entry and the grid will also be along 7th Street (see the map below). Formation laps will be short, and any "wave offs" of starts will result in laps being deducted from that race session and/or grid penalties for one or both karts on the front row. With only so much running time, we cannot tolerate poor alignments & "games" being played on the starts. After the checkered flag, the field will make another complete circuit to come back around to pit in. If the last kart still competing has passed the reentry point of the "shortcut" (on the inner-loop, turn 4), karts might be waved through the shortcut after turn 7 (see map below).

DO NOT PASS after taking the checkered.

Indianapolis Motor Speedway Track Map

The IMS kart track is a hybrid of the interior road course used by Indycar, Formula 1, and Motor GP and service roads. Overall, the track measures just over 1-mile. The track is ultra wide in many spots, measuring over 70' in some spots. While the service roads have some bumps (not more than some kart tracks), the interior road course is extremely smooth.

Following the suggestions of some very respected karting industry leaders, we have made a couple of changes to the track since the test. These are noted in RED on the photo below. The "bus stop", going onto the oval will be tightened up and much slower. Additionally, instead of the flowing right onto Hulman Blvd. coming out of the carousel, the track will now go straight and take a much sharper right ~creating another passing/braking zone. This should 1) slow overall speeds, and 2) add to the competitiveness of the circuit.

Tire Purchase & Use Rules:

Each driver (not entry) must purchase one (1) set of tires through USAC. If you are running multiple classes, feel free to use the same tires in each class (however, that is not required; just trying to save the karters money if they so desire). If you are running classes that use different tire brands, you are still only required to buy one set total through USAC; however, each class will be required to qualify on 'sticker' tires.

You may practice on any brand/compound you wish (don't blame us if you practice on X and get tight in qualifying on Y).

If you are running multiple classes with the same tire brand/compound, you can run a) the same set in all classes, b) purchase 1 set per class through USAC, or c) bring one new set, in the wrappers, to USAC for inspection ~this may include stamping, chemical 'sniffing', and/or trading sets.

You must qualify on the set purchased from USAC & they must be stamped prior to leaving the grid for qualifying. If you choose to run the same set in multiple classes, they will be marked after qualifying of your first class and are therefore approved to be run in another class.

All Briggs, Yamaha, and KA100 Classes are only allowed one new set per weekend. After qualifying, no new ("sticker") tires will be allowed to be used in these classes unless approved due to damage.

Senior and Masters '125cc Shifter classes are allowed two sets of race tires for the weekend. Both sets must be stamped by USAC before qualifications begin on Friday, and one set must be the set purchased through USAC.
