As with all racing safety equipment, racing seat fitment is critically important, and the racing seat user can increase the risk of injury if they are not fitted properly.  A racing seat is an extremely important safety item regardless if you are racing circle track, road racing, drag racing, drifting or participating in any other type of motorsports event. The racing seat must support the driver’s full body and permit sitting within the vehicle’s confined space with as little fatigue as possible.

There are several high-quality racing seat manufacturers, one of them being the Jaz Products™ brand. Please refer to the general racing seat sizing chart below as a starting point for choosing a racing seat.    

This general sizing chart can be applied to both ADULT and YOUTH racing seats, depending on the motorsports racing class.  If you need a racing seat configuration outside of the chart range, please contact our Technical Sales staff for other options that may be available.

Properly Measuring Fitment for a Jaz Products™ Racing Seat.

STEP ONE - DETERMINE SEATED HIP MEASUREMENT

Locate a Yard Stick or Metal Tape Measure and Record Hips Width in a Seated Position as Follows:

• The GENERAL RULE when sizing a racing seat is to MEASURE YOUR HIPS while in an upright natural position while sitting on a HARD surface with legs slightly apart. The person being measured can wear normal street clothes during this process, as a racing suit will just add to the snug fit needed for both driver comfort and safety.  Be sure remove bulky stuff from the pockets prior to the measuring session.
  
  
• All measurements MUST be taken in ABSOLUTE straight lines. Please use a yard stick or ideally, a tire stagger gauge.  If you ONLY have a tape measure, DO NOT let it bend or follow the curves of the body in any way, as proper seat sizing and fitment will be compromised.
  
  

• Most STANDARD 'Off-The-Shelf' racing seats will probably fit a normal size driver perfectly. The racing seat manufacturers that Racecar Engineering™ represents have produced thousands of seats over the years and have optimized their production dimensions to fit almost every type of body.  

STEP TWO - DETERMINE PROPER SEAT FOR YOUR RACING SERIES

Once you have that measurement, you can then choose a seat using the chart below.  Simply find the type of car or series that you race, and you will see the series styles available, along with the range of standard production seat sizes using the hip measurement.

REMEMBER - Choosing a racing seat can be REALLY confusing, as it is very common for SEVERAL different types of seat styles from a manufacturer, to be available for use in one particular type of race car (i.e.: Sprint Cars, Late-Models, Drag Cars, etc.).  It is up to the driver, crew chief or car owner, to sort through all of the features and benefits of each applicable seat style in order to finalize preferred seat choice.  Many times, your chassis builders will have a preferred seat brand and style that they recommend for their race cars, so please check with them if they are available to consult.  

Finally, it you or your team cannot figure-out which racing seat would work the best for you, please contact one of our Technical Sales Associates and they will work with you (and also the factory is needed) to determine the best racing seat style for your type of racing.

If you DO NOT find a basic seat size that works well, you may have to consider having a custom racing seat made by the factory.  If this is the case, please refer to the CUSTOM RACING SEAT section listed below.
