Some OEM seats are Recaro even if they're not branded as such. That said, I don't think brand matters if it's OEM. Regardless of where it's coming from, OEM seats are typically held to a much higher safety standard than aftermarket. Watching ballin' JDM Bride seats fail a rear impact 80 km test shows just that.
In short, I don't care what the OEM brand is, so long as it offers plenty of lateral support, is light, and isn't made for big fat Americans =P
If it does come with Recaros, all I ask is for SP-Xs, haha. Such purty seats. May be a tad overbudget though.
Not all Brides are wide too. The Brides in the stock R32 GT-R are perfect for smaller Japanese peeps like myself =D
