Of course you could, we did not want Recaros lites, we wanted full Recaros which do not fit the FiST, hence the lites with no adjustable bolsters. We have had full Recaros in my '79 Indy Mustang Pace car and our BMW 320IS and loved them. So we bought our 2016 with stock seats and sunroof. We couldn't be happier, neither of us liked the lites enough to want to pay for them. Would have liked full ones in her Mustang GT California Special Coyote but was not available with the CS trim.
