Has anyone had fork springs custom wound? - Marzocchi Z

[KeepItSteel]

So I'm drawing a big blank in sourcing any x-heavy 65/70mm springs (part# 5141109, or I think 5141110 would work) for my Z2, and am beginning to wonder if going down a custom route would suit better.

Does anyone know how/what/where/what info the fabricators would need?
I can probably gather the spring length (150mm), diameter (tbc) and what I think is the spring rate (in this case 8.4).

Would it be a case of finding a suitable local machinist and having then turn a couple, or am I looking for a proper spring specialist somewhere?

Anyone had a pair made up for themselves?

you would need to go to a specialist spring company and give them the working max length and min length, outside diameter and critical inside diameter if there is a rod passing through, then the Kgforce etc they could then design what you need.

I've emailed a couple of specialists so will see what they come back with. I have no idea if they'll be looking for £££'s or a couple of bob, I wont hold my breath though!

For anyone else that may be interested, it appears that I have a couple of positive leads for having these springs made to spec. I'm still in the process of firing info back and forth but its looking like I can get a pair made for anything between £40 and £80 - including custom progressive rate. (several companies are quoting £120 as a minimum order value but I think they are larger operations).
Hopefully i'll be able to keep it closer to £40, and will feed back if they turn out well. From the info I've been offered so far it seem that the specialists really are.. specialists. Who'dve thunk?

Interested to see if you can get price to that level, im pretty much after the same for my z3's
