Does anyone know if the S2 will fit S1?
Specifically this?

Leather Seat Covers for Mazda RX8 Interior Seats 2009 2011 Tan 522 Take Offs | eBay

 

I doubt the covers will fit, but only one way to find out. I have S2 seats in my 04' and they are a bit different but bolt right in.

 

damn. I was hoping it would fit. The seats do look a bit different, but how far off is shape of the S2 seats?

 

They will fit the rear seats. Check the rear seat headrests. Some cars have more pronounced rear seat headrests. Compare them with these seat covers and check.

They won't fit the front seats. The shape of the headrests and the shoulder pads are different.
