Thanks for all the replies to my question: has anybody successfully lowered the seat in a Plus Series? I conlude, for now, that there are no examples yet. Would anybody, knowledgeable about the seat’s construction, be able to share if it is feasable in their opinion?
My understanding is that the seat runners are bolted direct to the floorpan, there are no timber packers as per some Trads that could be removed, so you would have to cut out and fit a sort of stepped tray (very invasive) to sit the seat base lower than the existing floor level
In a bonded chassis tub I think it would be very difficult to guarantee integrity / strength / crash safety after such an invasive modification to the floor
I've seen it done on Trad chassis race cars as they often remove the ply floor and replace with alloy plate anyway
