I'm considering buying four 20x10 Sport Techno wheels and running a front spacer so they clear the calipers. I'm thinking about a 10mm front spacer. Enough? I know the rears will need spacers, so they don't look out of proportion, width-wise. Is this too much hardware weight just to be able to perform front/rear rotations?

What are the offsets on the sport techno wheels you're considering. If a normal offset, like 50, they should clear the calipers.

The 20" x 10" Sport Techno is ET55. Would it still clear, without spacing?

I'm not sure what size brakes you have on your Cayenne. In the picture below of my 09 Turbo S, these are the 380mm front rotors with the OEM 21" wheels.

I think yours are likely smaller than this so the 20" diameter shouldn't be a problem (might be too tight on mine), but what I can't see is how much clearance there is between the caliper and the wheel spokes, and my car isn't here (Widebody conversion) where I can go check it for you, but if your current wheels are also a 50 offset, going to a 55 will only move it 5mm closer to the suspension strut and brake caliper (assuming the wheel design and spoke angle are similar between your current wheel and the new wheel). If you can measure with a ruler and you have at least 8-10mm between the caliper and the wheel spokes, then you probably won't need a spacer to run these other wheels (technically, you'd only need 6mm of clearance going from a 50 offset wheel to a 55 offset, but that would be a little too tight for my comfort level.

I have the 350mm, 955 Turbo standard brake calipers. All I need is 2-4mm clearance...

Hi
I have 955 turbo S (383Kw) with original tehno rims. Front rim is 9x20, rear is 10x20. Everything works ok, but there is not so much space at front (maybe 4-5mm). If you will get original rims there wont be any problem.
