LP640,
I do not know if they will fit a G28, I am saying that the Scat seat is the smallest dimensionally that a long search has found and that they have the best chance of any to fit. Compare the dimensions given to your car and see.
Tallon,
I have never heard of a fully articulated racing seat and cannot imagine what sanctioning body would allow such a thing, especially covered in flammable material. Are you sure that you are looking at the Sportsman Pro on procarbyscat.com? If so, I am not sure what it is supposed to be similar to, I thought size was the issue here.
