Shaft Diameter on BC BR's for air cups

[untakenname]

Hi, I'm looking at getting some Stanceparts Aircups fitted to my RX8 as I'm having difficulty getting up a slope to park.
I asked BC what the diameter of their BR coilovers shafts have but they haven't got back to me yet, does anyone know what the diameter is and if it's the same for all their BR series of shocks?
I spoke to one person who had them fitted to his RX8 with Meister R's and he said that the rears don't drop with aircups due to how the suspension on the rear is constructed, does anyone know of any workarounds?

Cheers.

Hey there!

You would need to speak to BC directly for the shaft diameter as it changes brand to brand and across the model ranges!

Unfortunetly the RX8 rear won't accommodate the aircup due to the basic design of the rear suspension, i can't see a way around this being possible im afraid!

The rears are just too small.

Cheers, thanks for the prompt reply.
Guess it's fronts only, will that impact noticeably when raising the car for speed bumps?

Yeah, just wondered as if they were a set size it would save the effort.
I jacked up the car this evening and measured the diameter tonight and it's 12.5mm if anyone wants it for future reference
