Comparing the MF curved arms va the straight arms, seems to me the straight ones are stronger.
Think compression & extension forces vs bending an arc.
Dave's comment on modding the OEM arms has merit: my Duster (sig pic) had the front leg widened about that amount by Jack Arnew back in the day.
Car goes straight as a string @ 130 at the track, runs about 7 deg pos caster.
Wheels remain vertical during wheelstands with no bump steer when it sets down.
Only side-effect is it self-centers aggressively, don't have your hand between the steering wheel spokes when it centers.
Depending on the combo, 3.5-5.0 works well on the street.

Not sure if this is of any concern, but the MF arms are made with chromoly tubing and US sourced. I know most other brands use mild steel tubing. I’ve never had an issue with strength and the only two times I ever seen them bent in 15 years was due to severe accident impact. If fact, when the guys 1968 Barracuda got clipped and hit the side roadway, it was still attached to the spindle when the frontend came off the car.
