Going ahead with this mod on my Nova, I have the strengthening plates (old Chris Astley ones)

What's the besty way of fitting them, seam around the lot or stitch them on? Does either make a difference to stiffness/ability to bend?

Am I right in thinking the Corsas that are strengthened already are stitched on?

This might be worth a read Iain: PRESSME (http://www.pngclub.com/forum/showthread.php?68914-strengthening-bottom-arms)

Cheers Southie, although that thread discussed the pros and cons but not the actual welding of the strengthening plates. (Unless work Internet is blocking pics)

I wouldn't do one contentious weld, it will warp. Corsa GM ones are stitch welded

Ooh neat welding lol Wish mine are going to look that neat. I think I've been convinced they need to be stitched, cheers all

Thanks for the info Gareth, stitched it is. Inch on/inch off or something will do me

Stitch welds are supposedly better as if a continuous weld cracks it will not stop but a stich weld will contain itself. Some degree of flexibility is still needed imo

Continuous will be stiffer but more prone to cracks which will cause it to fail entirely, and you'll have to be careful about heat. Stitch will only crack across one stitch at a time, but be less stiff, and more prone to water ingress/rust.
