This thread is amazing. Big thanks to polar and Dave for continuing to innovate and coming up with creative ideas.

This is one caliper from the "CSL" kit... Six piston's up front, four in the rear... Cut and brackets for the OEM CSL size rotor!

So is the 6-piston Cayenne caliper you're using the 17Z (330mm crotor) or 18Z (350mm rotor) caliper? I'd assume the 18z based on your rotor diameter, but some of The VW and audi guys that have been using these calipers forever on their cars have mixed and matched them with various off the shelf rotors (MB and Volvo come to mind). The VW Touareg also uses the same calipers. The 6 Pistons can be sourced for a few hundred dollars per set.

Edit: I forgot that the Audi Q7 also comes with either 17z or 18z calipers (don't recall which).

Those were originally 18Z calipers, but were converted from axial mount to radial mount using a CNC. When using a 345mm CSL rotor, the 17Z pads are required to mate to the rotor surface properly, which will sweep the entire surface area perfectly.

The 17Z could be made to fit, but the front bias would have been way, way way too high due to the piston sizes in the 17Z (34/36/38mm) compared to the 18Z (30/34/38mm).

Polar, is this something you would be able to do for an E9x M? They have nice rotors worth keeping, as are being used here, but can benefit from a caliper upgrade like this. Wondering if there is any scaling from this project (maybe just a unique caliper bracket?) or if it would require a complete re-engineer.

I could absolutely do this for an E9x, I would just need one for a little while to develop and test on. I eat my own dog food, so to speak, so I'd want to have an E92 I could push around a bit to know the kit works well. Essentially, it would likely consist of the same kit that's on my E46 M3 with the E92 front/rear rotors, 996 GT3 rear calipers and modified 18Z front calipers.

Awesome! Now to figure out how to get you some seat and tooling time around an E9x..

Are the 18Z Cayenne Turbo 6 piston calipers pretty much the way to go now? I realize the caliper selection has been an evolution.

IMHO, not really. The problem is that they require a very precise CNC operation that is irreversible. Sure, I love the dynamics, good pad selection, HUGE pads that dissipate tons of heat, and bolt-through-bridge design that makes pad changes a cinch, but getting them to that point isn't a simple process unfortunately.

Interesting. What is the next best setup, all things considered? Boxster S/996 still?
