944 aluminum rear trailing arm info

I'm not 100% on this, but doubt it. If I'm not mistaken, wouldn't the 43mm push the wheel mounting surface out past the fender lip on its own? No wheel offset is going to make up for that. If you went to 1-1/4" wider fenders, then yes, with the right offset you are fine.

That was my thought as well. I will keep looking for a steel right rear control arm.

is this 43mm or 74mm per side or for both sides?

Per side. I have late arms with 951 brakes/rotors, 8.5"ET48 wheels and 3" fenders and the wheels nicely meet the fender lip.

I just got the late trailing arms without the bump stops, but when I compared the early and late, it looks about the same! Could it be the rotors that widen the track? Or the early alu arms came with bumpstops and without.

Without bump stops L side: 951 331 513. 8R
R side: 951 331 514. 8R

With bump stop R side: 951 331 514.1R , 951 331 514.0R
L side 951 331 513 1R

I have 1 extra right side with bump stop.
Could it be the hubs, rotors that increase each side by 31mm?
