I stopped by wine country motorsport to try some seats. I have the same problem as you. For me the Sparco EVO II QRT and the Racetech RT4119WT fit better than the Recaro.
The racetech is better fit but that seat is huge and i have no idea how it would if in a s14 or a 370z. The Sparco is almost perfect but i think I will have to take the cushion out when I wear a hans device.
