So I think this should be OK. I do not have bellypan, so I can't say if it is same with bellypan.
Engine casings - definitely yes, I am goint to buy CarbonAdi carbon covers for engine. I learned hard way that to protect right side cover you probably need mile long protector

Crashpads I posted - GSG Moto cost 30-35 euro per pad + 15 euro for 3 "damping" caps. I think this is cheap. Mounts for Firestorm, same as older model GSG Moto.
Metisse cost 89-99 euro per set of 2 "shock absorbing" pads. But I do not really like them. No mounts for Firestorm
Gilles tooling pads are same principle as Metisse, but I think cost well over 100 Euro. No mounts for Firestorm.
Lightech supposed to cost 60 GBP per pair of bobbins, but they do not make mounts for Firestorm.
I think I will turn pair of UHMWPE or Delrin bobbins on my old lathe, then buy caps from GSG Moto and then install bobbins on rubber shock like Lightech by turning "sliding bushing" from piece of aluminium or steel. E.g. will use both solutions.
My only problem is price of Delrin on eBay. Or rather price of postage. I want bar 80 mm diameter 250 mm long - this is about 20 GBP but + 20 GBP for postage this looks almost like price for pair of GSG Moto pads. I am thinking hard what to do...In Belgium chances to source right material equals to zero, so I have to rely on UK eBay.
