2016 heavy duty rear coils

[iggy_uk]

Hi,
I am new here, glad I could join.
I am hoping someone could point me in the right direction.
I have 2016 swb van and with the amount of load I have (parts and tools) it seats very low . chews through the tyres pretty fast. I've  browsed for heavy duty springs but it kind of takes me nowhere. found one set MAD , cost around £300. if that is it then it is what it is. perhaps someone here did theirs from a different brand. 
thank you upfront.
Iggy

Very little made for the Berlingo B9, many of us have been looking for years, spoken to manufacturers with no joy. H&R make a lowering spring but no one makes a higher duty one than the standard Enterprise 800 springs.

Stick some coil spring assisters in there to level it up a bit, available for caravan towing and the like.

thank you, I am inclined to check those 'MAD'. I have three B9 so will try one with MAD and perhaps one with assisting springs to see whats better.
