I've got Compomotive 8 x 17" Grp A Fitment ET33 and wanted to know if I could get 6 Pot AP's with 356mm Discs under.
I measured from the centre of the Alloy to the inside egde which gave me a measurement of 205mm I then got a CAD drawing (see below) that give me a measurement from the centre of the disc to the outside edge of the Caliper of 197.66mm So i looks like they will clear by 7.34mm.
But the question is do you thing this enough clearance?

the radial clearance seems to be ok, however it depends where the rim/wheel starts to get thicker going towards the spokes. So the axial clearance could be an issue

 

I've got the old flat 5 spoke MOs ET40 with 356mm discs and AP 7040 6 pots - I had to design the bell to be a few mm deeper than usual, but they fit fine (2wd)

 

Was that to push the caliper further away from the inside of the spokes?

Yes - I've got sets of ET40, ET35, and ET33 wheels (and some ET25 RL7s), so the 40s were the worst case from a clearance point of view, and were thus what the bells were designed for.

 

So with mine having and offset of ET33 it should clear ok?

I would think so, if the car is 2wd and you can make the bells deep enough. You'd be best off asking Martin Hadland.
