I got the stainless steel struts but they're super stiff. Will this be a problem for the mounting holes in the aluminum frame? I'm worried whether the dropout plate or the holes or the threads will crack if the strut is not able to bend and reduce the impact load like the aluminum struts.

I made the mistake of not double checking or asking chat GPT to show me how it calculated its recommended thickness of 3.8 mm for stainless steel without holes for the equivalent stiffness of 4.6 mm aluminum with holes. Now it's telling me 2.7 mm. And that my strut at 4mm is actually three times stiffer than the original.

I'm wondering if I should take an angle grinder and cut a 1 mm deep channel into the stainless steel to reduce its stiffness. Or is this fine and I should leave it alone?
