Rear trailing arms
I'm sure this has been asked and answered here, but I couldn't find it. I see they make offset rear trailing arms, for wider rear tires, but is it really necessary, and at what width does it become necessary?
I have a 73 I'm doing a mild resto-mod on, and would like to go with wider tires, but I'm not going crazy.
Thanks in advance.

You can pick up a little room by moving the pb bracket to the top of the arm. cut and weld it

And if I go to a 245 or 255/45/19 will that clear?

My c3 came off the lot with 255 tires. So you should not have to muck with anything if you have corrected Back Spacing
years ago I used 285 rears on 10 x 17 and 255 front on 9 x 17. Both with 4.5 bs. It had great grip and looked nice now 18 inch has a good tire selection. Imo 19s would look out of place with our tiny stock rotors

Wheels are 18x9.5" with 4.75" BS -12mm offset. This matches the factory 15x8" with 4" BS -12mm offset and add's 3/4" inner & outer to the factory wheel.
You can check your car by measuring 3/4" from all points of the factory wheel to see if you will have any problems. With 18 or 19" wheels the e-brake cable is inside of the rims.
If you go more than 4.75" BS on a 9.5" wheel, then you might need to move the ebrake cable.
Here is the e-brake cable / sway bar clearance on my car.

With the factory steering on full lock turning right It did because the front spoiler doesn't fit well. (not factory spoiler) this I could fix and have a better fit. Then when I installed the R&P steering the full turning was reduced and no longer is a problem.

I went offset t-arms (global west) to be able to run 18x10 wheels.
