Seats For Loco

[cdubu]

I need to choose some seats for my imminently to be completed locoblade. So far i have been looking at playskool grp shell seats due to there ligh weight properties. I have heard that these are not very rigid, has anyone got any advice about seats. I have also heard a small rumour that Tillet (caterhams) seat people may be making seats for other sevens???

Thanks
