E86 Front Triangulation Braces Retrofit

Not sure it will do much since the core support is quite flimsy.

Would for sure need to further triangulate from the core support down to the chassis rails. Basically emulate what BMW does in their newer cars with those fangs/nose hairs you can see through the kidneys.

Hard to say how much it would be worth it though. Would be interesting to grab one of those newer cars and measure chassis rigidity with and without that bracing installed.

I've seen a core support from a convertible e46 and it didn't look like the flimsy stamped metal piece like the coupe / sedan, it was much more rigid. Maybe that's an option?

Weird..same part part for M3 convertibles and the M3 sedan and non-M except for convertibles...

Here is the convertible part #. Looks like it is plastic with some stiffening ribs on the underside which the metal part does not have. And it only costs $900!

Word is that Slon tested this part on his chassis rig and it made near as no difference. If it does make a difference I’d bet it would be on cars with big front sway bars. Like lowered cars with destroyed front suspension geometry

How about tying to the engine block and making it a stressed member of the chassis F1 style

That wouldn't surprise me. The upper half is riveted to a steel bracket which is riveted to the lower half. If anything, I think it would sense to tie into the lower part or the frame rail or make the entire frontend clip much beefier.
