The Verizon IndyCar Series is one of the most unique forms of motor racing in the world where most of the components that the teams use are the same for all the teams this is from everything from the Dallara chassis to the wheel nuts that they use.
Paddock Eye decided to look into the technology surrounding tires and wheels in the Verizon IndyCar Series and with the help of Dale Coyne with Vasser Sullivan Racing’s Sebastien Bourdais’ chief race engineer here is what we uncovered.
We started out by asking:
Are the wheel guns manufactured in house or are they supplied by an outside company?
Our wheel guns are made by Paoli. Technically you could make your own, but I don’t know anyone doing that in Indycar.
Are the wheel nuts produced in house or by an outside organisation?
Wheel nuts are spec and made by Dallara.
How many practice stops do your mechanics perform before each race?
At the track we do three practice pitstops before the race. That’s all we are allowed by IndyCar rules.
Do Dallara have any input in the development of the wheel technology?
The only allowable wheels are from BBS or OZ, and are spec. I’m not aware of Dallara being involved with the design. These haven’t changed in many, many years.
How closely do you work with Firestone in developing the wheel technology?
I’m not aware of Firestone being involved in wheel development. If you mean tire development, Firestone invites certain drivers and teams to do specific tire testing. Those are typically the big, highly funded teams like Penske, Ganassi, or Andretti. We have not yet been asked to be a tire test team, though at one test Firestone did ask us to check a couple of options.
