The Recaro covers and cushions will fit Hahn,PPs and SPGs, not sat in a PP so you may be right. It's ages since I got mine and I've no idea on his current prices are. The biggest problem with them all is loss of rear seat access but the weight saving is substantial and I do find them comfortable.
The SPGs are high sided and a struggle to get out of in tight parking spaces.
