Nice CAD Model
Just a few questions/suggestions:
1. Make the rear end solid where the cutout for the rear bumper usually is. Carbon and (first version) DIMEC chassis' are prone to breakage there, it'd be a shame to see that happen to your prototype part. With a cutout in the RR hanger (Spec B hanger) and a Spec B bumper you'll be able to use bumpers again.
2. I'm kind of missing a longitudinal shorty layout? It should be the weapon of choice on high grip.
3. Is it for personal use or to eventually put for sale? Either way, have you considered having cut out a plate and 3D printing the sidepods? The resulting chassis will likely be more flexible than the original chassis, but it should significantly lower cost as well as increase the flexibility to alter your design (after all, the sidepods will define the battery placement in your design).
4. What is the wheelbase of your chassis? Kit? Longer than kit?
Anyway, it looks really good. Updates on the 210 are long overdue, so you're starting to see people doing their own project work on it. I too am looking at producing a custom chassis (for personal use).
