If you check my link, these are avalible, and these are the seat that I bought, they do fit, with some mods to the stock bracket. The dimensions are posted on both seats. The seats I bought are 20.5" with across the bottom, this is pushing it. The seats that you are looking at are 22" across the bottom. So, I would not be suprised if they did not fit into our MSP's. The seats that I bought look good, and they have MAZDASPEED embroidered into the head rest. If you are looking for cheep seats I would recomend going with the ones that I bought, that link is for a current bid with buy it now option of 185.99 + 160 Shipping. The seat that I bought were shipped on time with no problems. Another reason why I wanted to use the stock brackets is because I wanted to keep my stock seat belts. Our seat belts are attached to the stock braket and I did not feel like trying to reattach the the seat belts to new brackets. If you decide to by these seats let me know I will try to give you as much help and advise as possible.
