I bought a pair of similar seats but soon found they woun't fit because of interference between the front inside corner of seat and the floor hump. I adapted them to the original seat rails to keep them properly centered, but maybe would fit if moved over almost against door, not very good for comfort. replacement seats cannot be any thicker than original seats for best fit. At lest that is my experience, so gave up on that idea and kept original which were in good shape anyway, I just wanted different ones.
I think those seats your looking at are not worth consideration. Real so called racing seats cost a lot more than that !
Has anyone found seats that will fit ?
