This is an interesting question. Did anybody in the know tell them that a curved set was necessary for the "extreme" setup? Did they figure it out on their own in their track testing w/ Tommy T's or Justin's car that this was necessary? Did they consult w/ Justin or Les? I hope that I'm wrong, but if it wasn't brought to their attention, I'm guessing that it's unlikely that they will be curved. Please understand, this is in no way meant to be a put down to G.C.; just my random observation. I hope that they are a curved truss design.
