This is a genuine BRIDE product. 

These are an excellent option for individuals trying to mount side-mount fixed bucket seats into their AE86. These seat rails are made with top-notch quality materials and come in a sleek black finish. Bride has provided dimensions of the rails, but if you already have a seat in mind, the rails are compatible with:

BRIDE: Fixed bucket seat series, edirb 031 / 042 / 061 / 067 (excluding the ZETAIII Type-XL,ZODIA)

RECARO: SP-G

SPARCO: Pro Drive

Other: AAR Racing, COBRA, and other Seats within the mounting dimensions

We offer these in both LH (USDM driver side) and RH (USDM passenger side) configurations. 

These Type FG rails replace the discontinued Type FO rails, and fit the same seats as the Type FO rails, though some adjustments may be needed.
