Hi,

When I was working as a teacher in Automotive I got to look at all kinds of COP set ups, I was shocked when I saw all they used to create a contact was a small coil spring! when I made my fist COP set up (search the net) I custom made my own springs similar to OEM and under the PECO scope analysis there was no drop in Kv (use magic wand probe), and over the course of a few years testing in field they were faultless.

This system of mine is far improved in that it accounts better for miss alignment but also uses a bespoke spring (me and my father manufacture these!) with much higher pre load assuring a positive constant electrical contact a permanent one. IF you pull apart many OEM and after market wires and see just how fucking shit the contacts are on the posts of coil and plug you would be shocked what you find, at any point they are just single point contact but with VERY POOR clamping to either item! they really only work with the rubber boots creating the constant load to keep them in touch with the mating parts......... very poor system.

In regards to the 'excess material' on the coil 'F' and 'R' brackets, that is because there is an offset to the Trailing coil has a +4mm offset and this is reflected in the mount, to save me standardizing the COP adaptor (preferred) I decided to have offset coil mounts (so this is why one side lines up to the coil tab on the top coil and the other side lines up the the coil tab on the bottom coil, this could be machined off but then it would look line a leaning tower in Italy so best to leave it as is.

Hope that explains it.

Oh and in regards to making other stuff to suit other engines.
I would need confirmation of the plug locations (FC housings) as measured from the bottom edge, also a mounting location on the center plate, and a verification of the T & L plug recess in relation to the mounting point (best to email me) as I would send a drawing of what you need to provide me to design it to suit your application).
