Default Efra ruling

I have a question about the wing in 1/10 Nitro racing. In Efra ruling
is it allowed to cut off the side dams from the wing as to have only a curved
wing without side`s. Does anyone have experience with this or have seen it in sedan racing.

I would think that it would be legal, but why on earth would you want to destabilize the rear-end like that?

Believe in oval racing can cut off the dam one side. Sedans follow rules on EFRA. I run ROAR, sure the rules are simular. Have to read EFRA rules.

From memory, I know that the dams cannot be bigger than a certain limit, but I don't remember seeing anywhere if it is legal or not to have them completely removed.

Like I said, as far as I can see it should be legal. I just think it would be completely unpractical to actually do it!
