A quick test is to measure the outside width of the seat near the front and see what it is. You can get approximately 20 inches of width in there with the shifter on the right and the e-brake on the left. That has been the limiting factor as I was changing seats. The tubular (Corbeau), composit (Sparco, Momo) have about 2 inches on both sides of padding and rolled edges so you are left with an inside maximum of about 15 inches. That is why I went with the aluminum seat as it only has 1/2 inch of width added to the inside measurement and you can reshape them if needed! Good luck.
