I'm working on making my own custom seats using stock 914 seats and grafting on the nice large bolsters from a set of old E30 M3 seats. I'll also be using the thinner seat cushion from the M3 seat that has a thigh support attached to it. Looks like it'll be really supportive when done and should eliminate most if not all lateral movement. I need some help deciding what to cover the back and seat cushion with though. Bolsters will be leather or high grade vinyl but I want something that will be cool on my back (gets hot here in Texas). My idea is to use a black heavy grade nylon or similar material, with maybe a large diamond pattern sewn in for a vintage look and the bolsters would just be solid. Would the Nylon be good for a cooling material or have the opposite effect? I think the contrast between the black leather and black vinyl would work nicely but have never seen it used together. Anyone have opinions or suggestions on this?
