I always used Continental SportContact2s on my cars but was fed up with the abysmal wear rate on the rear so when I was offered Michelin PS N1s for a good price I replaced the rears with the Michelin and kept the 6mm tread Continentals on the front.

Suggestion
If you don't want to replace all 4 then keeping the same brand, type and N number on the same axle would probably be the next best compromise and accept that the car on the limit may handle slightly differently.
Leading evidence: 'Replace rears' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace 4' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Quick question:
I've read all through the various threads and stickys about N rated tyres and the suggestion (from Porsche at least) seems to be not to mix N ratings.
This is all well and good but my fronts are Michelin PS2 N1 with a load of wear left in them and the rears are PS2 N1 as well but need replacing.
Question is, is there any REAL reason that I can't get the PS2 N3 which is all anyone seems to stock now, I can't get PS2 N1 rears anywhere.
Thoughts please?
Technically the N1 and N3 PS2s can be different in terms of compound, structure or tread design. In the ideal world you would keep them all the same but there has been supply problems with some Porsche sizes. If you don't want to replace all 4 then keeping the same brand, type and N number on the same axle would probably be the next best compromise and accept that the car on the limit may handle slightly differently. I always used Continental SportContact2s on my cars but was fed up with the abysmal wear rate on the rear so when I was offered Michelin PS N1s for a good price I replaced the rears with the Michelin and kept the 6mm tread Continentals on the front. I did notice that the car understeered slightly more when pushing on under power but most probably wouldn't have noticed it. Didn't mind slightly more understeer but definitely wouldn't have been happy with a twitchy rear.
Generally not a good idea to mix on a 4WD, but fine on a 2WD.
As above, the handling on the limit will change, but will not be dangerous - just different.
Also, Porsche will happily renew warranty etc with what you describe - N rating is the main thing to watch for and try and stay within brand if possible.
I'm currently running P-Zero's, I believe the fronts are N3's and the rears are N4's... or the other way round... and seriously I don't give a toss if they are different N ratings as the car has never felt anything but sure footed... my main concern is to ensure all 4 tyres are the same make and type... just my 2cents
...but also don't forget that tyres wear by up to 7mm, so which gives the 4wd/PSM more issues...
new-fronts+worn-rears of exactly the same tyres, but NOW different diameters (due to worn rears),
OR
new-fronts+new-rears of different tyres with the same diameters.
