Hi peeps, Im going to build a new seat from aluminium profiles. My question is about the racing seat. When i look up internet i see prices ranging from 150 up to thousands of euro's. Within the pricerange of 200 - 400 euro's what is the difference in quality? They all have adjustable back and they all come with a sled. They differ from material fake leather to syntetic. I must buy them online so i cant test it beforehand. Anyone advice?
