Topic: Seat rule question

Hello again,

I've got another question regarding the safety rules:

3.F.1.a General Driver’s Seat Regs. Driver’s seatback must reach above middle of helmet or higher. One-piece, purpose-built racing seats with properly located, factory-provided shoulder-harness holes are mandatory. Molded plastic seats of ABS or similar material are not allowed.

Does this mean it has to be metal?  It would seem that if that were the case they would just say it that way.  What else can the seat be made of?

Re: Seat rule question

Seats cannot be plastic. Seats can be fiberglass, carbon fiber/kevlar, tube frame, or metal. Most affordable seats are aluminum sheet metal or fiberglass.

Common affordable seats are Kirky aluminum seats, or seats like the Corbeau FX1 fiberglass. You do want to consider going to a full containment seat. It's not required, but it is safer in a crash, so at least weigh the option and decide if it's worth it to you.

Re: Seat rule question

They mean they don't want to see seats like these that are molded plastic. https://cdn.shopify.com/s/files/1/1441/3960/products/2000BT_grande.jpg
