Cheers to all for there input so far.
Maurizio, I did wonder about the bennefit of the small (yellow) piece, but figures that it doesn't weigh much so it won't hurt.
The lightening was done after seing that holes drilled like that don't compromise bending strength by much. The tube is 30mm square, 2mm thick and the holes are 13mm spaced 20mm appart.
A brace undeneath has been considered, but it would have to be made from some pretty small stuff. Maybe 15mm square tube would suffice, even tho the car isn't as low as it use to be.
As for it's worth on a road car. Well there is no such thing as a chassis that is to ridgid, even for a road car. The engine is coming out anyway, so I see it as an opportunity to put some effort in where AR didn't.
I know that the RSR system can supposedly be used without additional bracing and maybe I am wasting my time. But I've never thought to myself when driving an Alfa "Gee, this car has a nice solid feeling chassis that should be able to handle massive spring rates.
