IMS Pit Entry and Parking

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. 

Pits will be on the inside of Oval Turn 3 (in the upper right of the photo below). The viewing mounds just south of the pits provide an excellent overlook for most of the track. Just south of the kart track, the USAC25 (1/4 midget series) will be competing at the same time. Participants and fans are encouraged to visit both events if they so desire...

IMS Oil, Fuel, & Tire Rules:

Approved 2-cycle Oils:

  • Burris Blend

  • Redline

  • Motul GP 2T

All mixed at a maximum of 8oz. per gallon

 

2-cycle Spec Fuel:

  • VP C12 in 5 gallon pales.

Pump 4-cycle Spec Fuel:

LO206 classes will run a spec 87 Octane pump fuel from the Speedway Gas Station on W. 16th St. (across the street from the main entrance to IMS). We will draw our samples from pump one and if it is out of service, the next lowest number working pump (2, 3, etc.)

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 (i.e. Yamaha Medium on Bridgestones & KZ Shifter on MGs), 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 new ("sticker") tires. 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 'TAG' and 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.

Tires will be $210/set tax included.
