not toyota but the good old honda prelude seat swaps easy to do as well - and are very comfy .. it raises your seat position a bit though , which i see is the only downside
ive heard of others fitting MX5 seats - which are also nice , and silvia seats ..
Mx5 ones seem to sit more lower than the prelude ones which are a plus
Ive also seen GT4 seats from an st185 in a ta22 as well
