heres the info on the bottom mounted seats.as you can see from the two posts some seats even made by same vendor recargo, sparco need different mounts some bottom sliders some side..heres the rest:
Until now, there was not a reasonable and reliable performance seat mounting solution available in the United States for the NSX. Hand-built in Japan especially for the NSX, the TAITEC Bottom Mount Sliding Seat Rails are designed to mount bottom mounting seats such as the Sparco Torino.
TAITEC Bottom Mount Seat Rail with mounting brackets
The TAITEC Bottom Mount Sliding Seat Rails utilize factory mounting locations for a plug-and-play installation, and do not require drilling.
Seats with bottom seat mounts are typically for street use and reclinable. Seats such as the Sparco Torino are compatible with these rails. Seats must have a 4 hole bottom mount dimensions of 275 x 345. Not for use with side mount seats. TAITEC Side Mount Sliding Seat Rails available here.(sos site)
