Tire rubbing, Need to stretch the rear fender a little. But how? Options

[HansJan]

Today I had new rear tires installed. A family member has this size tire on his 914-6, and it looks great. So I got the same. 225-50-16 on 7” rims.

They clear the fenders (which had been rolled by PO). Passenger side has plenty of clearance at 1/4”. Driver side not so much, just enough to slide a thin cardboard between tire and fender while bouncing on back of the car.
All is fine in a straight line. But Passenger side starts rubbing at right-hand turn.
See pictures below to spot the rubbing location (paint starts to blister a little).


Should I try to stretch the fender a little?
Or...
Is it possible to create some room by adding a shim to change the camber?

Thanks for letting me use the collective brainpower.

My reply @ one stage was it was thats a large tyre for a narrow body ???.
A 205/50/16 offered a good footprint on the road besides something, like 8.1inches more than enough unless you have HUGE horsepower.
You are trying to reinvent something that won't work...no intent to be rude but that the facts.

205/50/16 has a total outside diameter of 24”.
I would prefer to have 25”. It keeps the speedo honest, and rpm low at highway speeds.
Thanks for your imput.

Why not try a 205 or 215 /55-16?

I have two sets of wheels - 951 8s and 7s and 911 7s and 6s. My plan is to run the 951 8s (rear) and 911 7s (front) for the street and the 951 7s (rear) and 911 6s (front) for the track. I am going to try to find the widest stickiest tire for each to fit under as close to stock rear fenders as is possible. If that means running 205/50s on the 8s, then that is what I will do.
