I know what you mean, but none that I can find. only a few aftermarket Bucket seat sets of Sparcos and Recaros etc which seem to be resin copies of Tamiya Race seats.
I'm after a set of adjustable seats like these :
The best looking seats IMO are the ones from the Tamiya R34 Skyline kit.
Which with a bit of work could be made to look the same, and then cast from resin (I'll have a go soon)
