I'm looking for a AE86 GT-S seat, as mines really worn out.

I'm not sure if the little lightweight lumbar adjuster came on all the seats, but I'd like to find a seat with a bolster adjustment that never loosens and has the tiny little lumbar pump.

My seat is already pretty worn out, so every-time I go to an event I have to try and brace myself against the side of the car because the bolsters on my seat spread open the second any pressure is applied to them.
