Low hanging fruit. Go after the low hanging fruit. I mean if you are just bored and don't care about lap times or competition, go ahead and knock yourself out. If you do care, get a real wing and know that I don't see active aero being allowed in time trials or time attack anytime soon.

With the amount of cars coming with it OEM , I expect it won't be long.

I don't know about NASA, but I do know it's on the radar to be talked about with other groups.

Again, for me this isn't even a plan. It was "this would be a fun project", "I bet I could control that with the race capture", and "linear actuators seem slow, weak, and expensive". That's as far as I got.

Too bad the supply of cheap COTF wings is dried up, for the most part

I would expect an OEM Aero adjustment for those cars, but I don't see aftermarket active aero being allowed especially in NASA where the goal seems to be to remove aero from classes below TT3.

Isn't NASA pretty liberal with the front splitter and diffuser in ST1-ST3/TT1-TT3?

King Tut

Yeah the only thing they have banned are front wings, but you can have a 10" splitter if you want.

All I could find was: "Aerodynamic devices and/or modifications may not protrude more than six (6”) inches from the vertical plane from the ground to the widest part of the right and left sides of the vehicle’s body. Front wing/spoiler/foil/splitter may not protrude more than 12 inches in front of the outermost edge of the front bodywork/fascia, and may not be higher than the lowest part of the vehicle’s hood.

That looks like any shape as long as it is no more than 12" in front of the car and less than 6" wider on either side, 12" total. That would be WTAC range. I thought I must have read it wrong.

The rear wing looks pretty open also: "A rear wing (or rear spoiler for wagon-style bodies) may not exceed a height of eight (8) inches above the roof-line (or OEM windshield height for convertibles)."

I couldn't find anything on rear diffusers.

That sounds like a huge front splitter with side plates and diffusers and a rear wing potentially a foot wider than the car.

It seems extreme. Is that correct?

Follow up: NASA ST1/2/3 wing/splitter rules are near identical to WTAC. Both can be 6"/150mm wider than the car, with the rear wing 8" above the roof. WTAC can also be 8" behind the car. The front splitter/wing can be 12"/300mm in front of the car. WTAC cars have massive rear diffusers and very tightly ducted cooling systems but in what I've seen the NASA cars don't. Is there a reason for that? It also seems that NASA allows alternate suspension links, dropped spindles, and widening the car (which would also widen the wing, rear diffuser, and splitter). Has anyone done that? ST5 calls out a modification factor for over 4" increase in track, prohibits the dropped spindles, but ST1/2/3 doesn't seem to. Moving the wheels out would create more room for managing the aero.

Are there unwritten rules in effect?
