Question Exhaust Tips touching Agency Power CF Diffuser w/ AA Midpipe installed (Pics)

Just finished installing the AA midpipe, made all the adjustments and despite the F83s extra body reinforcements behind the differential, there are no pipe contact issues.

However even with wedges and more adjustments, there is .5mm to zero clearance between the Mode Concept Ceramic Coated exhaust tips and my Carbon Fibre Agency Power Diffuser. I was hoping for at least 1mm of clearance, should I be worried about the diffuser melting at the contact points? (Pictures attached)

I was thinking about adding some washers to the two actual muffler hanger undercarriage bolts to add some clearance. Should also add some clearance to the convertible’s extra underbody sway bar which currently has about a 1.5mm spacing from the AA midpipe.

Any thoughts?

Are the rear muffler hanger mounts adjustable?

FIXED: put a few M8 washers underneath each muffler hanger bolt (body side). Lowered the tips a few mm away, no more contact or rubbing.

If the midpipes aren't all the way home on the muffler pipes or if they aren't cut far enough, then the midpipe pushes the muffler back and up higher than it should be.
