OK I have tried every permutation of angle offset on the COP adaptors and IGN-1A and stacking vertically is a fucking nightmare, because the coils are Asymmetric it means there is very odd arrangements for the Fr and Rr coil modules (and it just looks shit house as well).
The is no elegant solution available around that coil design except to mount them horizontally as I have in my compact 2nd version.
If packaging space is an issue I'd say stick with ign leads and where ever you mount your coils, or go race car spec, or wait till I design the CDI (latest gen M&W coil version).
The IGN-1A style coils are just fucked for packaging as you can see.
done the best I can with it, so unless I dream of a solution then this will be it for these........................
