If itās for KZ I donāt mind it, cool to see different things at the ultimate frontier of karting.
My father was right saying KR has their own Adrian Newey
With the damage I see on the underside of karts from kerbsā¦looks like much ado about nothing. Those skirts will never live at many tracks. Something for the premier category to play withā¦not us.
Donāt think it goes beyond the cross rail in front of the seat, which meets the regulation.
Having said that, thereās nothing stopping a seat shaped to take the flow from the pan and do something with it.
From an aero perspective, I canāt see how this works. Its got a the leading edge, it looks like they are trying a diffuser throat using the frame rail, then it just ends. Thereās no trailing edge air expansion space. It just ends with the frame rail. So Iād think itād create a high pressure region under the kart.
Iāve looked at developing a seat that is a diffuser as well. That is within the regulations. Zip tried a full floor and difuser in 1979 but withdrew because it was a bit on edge regulatory wise.
The FIA regs state
"4.6 Floor tray It is mandatory to have a floor tray made of rigid material stretching from the central strut to the front of the chassis frame. It must be laterally edged by a tube or a rim preventing the driverās feet from sliding off the floor tray. The floor tray may be perforated, but the holes must not have a diameter of more than 10 mm and they must be separated by four times their diameter as a minimum. In addition, two holes with a maximum diameter of 35 mm are allowed for steering column and/or gear shift lever access. The floor tray may be made of composite material. "
Interestingly Motorsport UK regulations would outlaw this pretty much.
"16.6.1. The floor tray must be flat, with any deviation allowed upwards, and not downward.
It looks like theyāve tried to extend it behind the central strut. Iād assume it then becomes ābodyworkā and canāt be used as it isnāt homologated. When I was designing my seat idea it was under the assumption any full length tray would be deemed ābodyworkā and thus need to be homologated. If itās stuck tot he sat and not attached to the chassis, thatās a workaround.
Iām catching that the FIA rules have been changing a lot since I cared more lol. It definitely used to say it couldnāt go beyond the cross rail in front of the seat, except superkarts, which can have a full length floor. Now the wording change has allowed a full floor (in my opinion) as long as it stretches from the central strut to the front of the chassis frame.
Ross Brawn would say it depends on you definition of up and down.
Looks pretty cool, but it looks like a lift generator. Seems like it would need to go under the seat and have a diffuser to make downforce? I am not an āaero guyā though.
The same rules apply regarding the central strut. This is a workaround. You turn the seat into an extension of the floor. I designed the seat to have a diffuser as well. I felt like just bracketing a floor on wouldnāt look too good from a snooping regulatory eye. itāll be good to see the idea tested though.
I had thought about what actually constitutes a ācentral strutā as itās not defined and it can affect how you approach SuperKart aero too (thereās a workaround to have the diffuser start earlier). Thereās nothing about where it needs to be from what I could see. So you could in theory design a chassis with this in mind and come up with a whole load of solutions.
