I may add one more lateral bracing bar in aluminium underneath the gearbox, but this can be a bolt-on or rivet&adhesive affair so doesn't need to be fitted right now. This may give me an additional support for the rear floor/diffuser later in the build.
Just a reminder for anyone joining the blog late, the work I'm doing here doesn't affect the rear suspension geometry in anyway. The fuel tank cutout will probably reduce the torsional stiffness of the chassis in that area somewhat, but counteracting that the rear upper shock mounts are now directly tied together and will be better than a stock Elise.
The well-known weakness area on all Elise/Exiges of the rear toe-links is being addressed by fitting the pilbeam style lower wishbones (watch this space) and by tieing that area into the main 50mm diameter bar supporting the gearbox.
