Hi,
I'm evaluating to build a front subframe using rectangular aluminium extrusions. I'm wondering if anybody did a similar work and have some suggestions/feedback to share.

I'm concerned about the suspension mounts. I would use stainless steel brackets to avoid corrosion, but I need to bolt them. My idea is to weld a small piece of aliminium tube through the rectangular extrusion and use it as a guide to pass the bolt through.

Any other ideas ?
