2026 Musselman Pit Spot Reservations

Reserving Your Pit Spot

As always, the toughest part organizing back to back large events each year is laying out and fitting everyone into the pits!

This year is no different, as the 2026 Superkarts! USA Winter Nationals event debuts at the popular Musselman Honda Circuit in Tucson Arizona this March.

ALL RACERS or TEAM OWNERS can do their part now by reserving the space they will need (as well as encouraging all drivers to get pre-registered for the event – before their classes cap out at 44)!

Due to the large amount of racers expected, the 300SF-per-driver rule will apply. Racers and Teams will be limited to a maximum of 300 square feet per entry. Pit requests must include a list of pre-registered drivers to be considered complete. If you know EXACTLY how much space you will need for your pit spot per the attached pit map, please email – a complete PDF drawing (no photos will be accepted) – to This e-mail address is being protected from spambots. You need JavaScript enabled to view it . Emailed pit requests will be replied to with a confirmation within 24-48 hours of receipt.

NOTE: Due to the limited size of the paddock, ALL participant vehicles WILL be park in a designated parking lot across from the entrance of the facility. ABSOLUTILY NO vehicles will be parked within the paddock.
ONE (1) Vehicle pass will be issued per sponsor. Accommodations have been made for disabled vehicles with proper credentials. These are the ONLY two exceptions. 
SKUSA will provide support vehicles to assist with team supplies and customers who need assistance from the parking lot beginning Thursday March 26th from 7-9:am daily.
Additionally, there is NO camping or RVs allowed in the paddock regardless of use.

UPDATE 2/3/26
Pit Spaces going fast. 

Due to the large amount of pit requests already reserved, the existing paddock is 95% sold out. 
SKUSA has added additional pit spaces to accommodate the need.


On-Site Camping/RV Parking:

RVs and Motorhomes WILL NOT be allowed in the paddock. Toy haulers over 35’ in length will be considered RV/Camping vehicles and will NOT be allowed in Paddock.

Camping/RV Reservations can be made at: Pima County Fairgrounds RV Park

Pit Space Pricing:

The price of all pit spaces is as follows.
  • PIT SPACES 1-24 (12’W x 40’D) $1.00 PER S/F - SOLD OUT!
  • PIT SPACES 25-117 (12’W x 40’D) $.75 PER S/F - SOLD OUT!
  • PIT SPACES 116-147 (10’W x 20’D) $.75 PER S/F - JUST A FEW LEFT
  • PIT SPACES 136-157 (10’W x 40’D) $.75 PER S/F - SOLD OUT
  • PIT SPACES 164-206 (10’W X40’D) $.35 PER S/F - GOING FAST!
The above price is for you stay on-site for the week of our WinterNationals only (3/24 thru 3/30).

NOTE: As always, the event & class sponsors will receive priority pit spot placement AND ONE (1) VIP PARKING PASS, so be sure to note on your pit request if you are a sponsor, or if you'd like information on becoming one. An emailed request for sponsorship information can also be sent to This e-mail address is being protected from spambots. You need JavaScript enabled to view it .

NOTE: Please tell us in your pit request if you are attending the RMC America’s Trophy the week before!

Superkarts! USA and RMC will do everything possible to ensure that you can retain your same location for your entire stay for both events, if this is your preference. However, there are NO GUARANTEES. 

The paddock area will be rows of pit spots 12’W x 40’D, (BLACK numbers), and 10’W x20’D (RED numbers) and 10’W x40’D (BLUE numbers) so your drawing should reflect multiples of these areas. Please also specify your top 3 choices for the pit spot locations you prefer (i.e. 1-5, 119 121, etc), based on the pit map posted below. We will do our best to accommodate you.


2026 WinterNationals Pit Map

Updated: 3/11/2026

Here are THE ITEMS TO INCLUDE ON YOUR EMAILED PIT REQUEST/DRAWING:
  • Please tell us if you are attending the RMC event the week before.
  • Full layout – with dimensions in feet – of your total pit area. PLEASE BE EXACT, AND DO NOT REQUEST MORE SPACE THAN YOU TRULY NEED. Remember the 300SF rule! You will probably NOT be able to add space when you arrive.
  • Include space for trailer tongue, pull-out generators and trailer doors (side and rear). Allow room to get the karts or other materials in and out of the doors.
  • DO NOT include support vehicles unless they are moved in during the pit move in schedule and will remain stationary until Sunday after the final checkered flag. We are offering pit spaces NOT parking spaces for rent. Pit spaces are at a premium!
  • FIRE LANES are just that. They are not for kart stands, kart boxes or generator storage. EVERYTHING MUST be within your pit space footprint.
  • Assume that three sides of your pit spot are fixed positions with no access other than the entrance/exit marked on your pit map. Show us how you plan on entering and exiting your pit space with your kart(s) – in relation to the pit runners shown on the map.
  • Include where tents will go, trailers, E-Z ups, VIP area, etc.
  • NOTE: Toy Haulers will be allowed in the pits; however, you cannot camp in it overnight. All other campers/RVs will need to be parked in the designated RV area – NO Exceptions!
  • Tell us whether or not you’ll be renting a tent, bringing your own, or both (with notes on your drawing). See below for tent vendor info. Please note: your pit spot must accommodate an extra 5’ feet around your tent for the blocks
  • Include a team name and a list of the drivers (with classes) that will be pitting in the spot. NOTE: Please send your pit map when it is absolutely final. In the event that there are multiple teams in one pit area, a designated team manager or representative must be named as the person responsible for tent and trailer placement. We will NOT park teams on site unless and until ALL trailers are present – or unless the team manager is present (this is the only exception).
  • Teams that want to guarantee they are pitted next to or near each other MUST submit their pit request as ONE COMPLETE REQUEST to both RMC & SKUSA, together with a specific note on each section of the drawing and initialed by the person submitting the request telling us that preference. NOTE: Following this process will allow us to achieve this goal but may reduce the ability to fulfill specific locations due to size. If this is being requested by a sponsor, the sponsor must submit the request and be responsible for paying the entire pit invoice. Again, we will do our best to accommodate.
  • Include on BOTH your drawing and the email message your contact name and best daytime contact info -- phone and email address (Mobile number, PLEASE! Not just shop number).
  • Please add a note to your pit request with your arrival date.
  • NOTE: NO passenger vehicles will be allowed in the pits, so please do not include them in your layout. Pit space is at a premium! RMC and SKUSA will aid with transportation of supplies and passengers if needed from the front gate.
  • We will be in touch within 24-48 hours of your emailed request to confirm that each pit spot reservation submitted has been received. Then we will contact you and secure payment with you when we have you placed on the pit map.
  • Once you have been placed on the SKUSA pit map, an invoice will be sent to your email via TPK PROMOTIONS QuickBooks. Payments MUST be made prior to parking in the paddock.

Securing Of Tents

Musselman Honda Circuit has invested substantially in the complete paving of the entire paddock. There is NO staking of ANY tents. Blocks can be rented from the facility. Please email Bruce This e-mail address is being protected from spambots. You need JavaScript enabled to view it to reserve blocks to secure your tents if needed.
NOTE: The possibility of a windy day at the facility is quite great. We recommend you bring or rent enough weight to secure your tent.

Golf Carts, Bycycles, Scooters, Any Form Of Wheeled Transportation

In compliance with our insurance carrier, the use of any form of wheeled transportation is not allowed within the paddock. This policy will be strictly enforced.

Mobility vehicles for disabled individuals are the ONLY EXCEPTION! Proper disabled credentials are required and subject to verification.

Teams wishing to stay and test after the WinterNats need to contact Musselman Honda Circuit to do so.

Musselman Honda Circuit WILL monitor the paddock during the event and after. Teams are encouraged to police their pit, and return it as received – or fines will be imposed. ALL trash MUST be broken down and fit in the trash receptacles provided on-site.
