Simpson have spoken to VWR and they are travelling, they couldn't understand why they don't fit.
I have updated Simpson as to the reason why, ie the different ball joint placement with TT arms, one possible solution outside sending back would be to have new bells made with a different offset and shim the brake caliper to suit. This would move the caliper out, it's a case of how much clearance the team dynamic wheels have between the wheel and caliper. I would consider moving by say 5mm, can anyone who has this combo see if this is possible ?
If not it's looking at AP's and seeing if the inner face of the brake disc with their kits is moved inwards by less than 3mm.
