After breaking 2 more upper bulkhead/diff cases yesterday, I really wish they would look at a new design for those.
Yes both times were direct sideways rear wheel hits on the wall, my fault and pretty hard hits. Just sucks that that's were it broke.
I can say the overall durability is great though. The bulkheads, the cvd axle and a bearing were the only casualtis.

Hmm. Sounds like it's the upper diff case that needs replacing, not the lower.
Looking at my TB-04R, I have the camber links mounted in the innermost holes on the tabs coming off the sides of the upper diff cases. Are yours mounted further out? If so, the forces exerted on the camber links will have to pass through more plastic, which happens to be weakened by being full of holes. Maybe try relocating the inner mounting points as far inboard as you can, and see if you get the durability you need.
EDIT: As you can see in this picture of the underside of the upper diff case, only the innermost camber-link mounting hole is actually surrounded by a meaningful amount of plastic. The next hole out is probably still okay, but the outer two holes have no reinforcement at all. It would be best to use one of the inner two holes, and if the outer holes cause clearance problems with the camber links, just cut the outer holes off.

old trick from back in the day is inserting a set-screw in each of the 'empty holes'... thus, filling in the gaps.
obviously you don't want the setscrews to be too long and want them to sit subflush to the top mounting surface so that the adjacent ball-stud sit flat as normal..
on another note, i used this back in my Yokomo YR4 and HPI RS4 Pro3 days...
haven't had a single issue with the Tamiya plastics in this regard.

Selling my still good aluminum chassis off of my USGT. The one on my USVTA car twisted like a wet noodle.
Car handles great with it. It helps tame the agressivness of the initial turn in.
I'm going to take the bent one to a metal shop and see if the can cut one from stainless.

Crickets on here lately. Did everyone sell their cars?!?
I normally only run VTA and USGT but this weekend I stepped up and ran 17.5as well. (3 Classes in one day is too much for me I have found).
I had hoped to just stay out of everyone's way and didn't anticipate running very well. Much to my surprise, the car was unbelievably easy to drive. Never so much as touched a pipe in the main.
At the end of the day, both Evo's brought home a win (VTA and 17.5) and ended up breaking out of the USGT main after qualifying #1 due to a nasty head on hit by a wrecked driver trying to get pointed back the right direction.
I have a few different chassis and I like them all. The Evo/Exo's still continue to be crazy easy to drive and respond very well to tuning. Awesome cars.

i hadn't much luck last weekend, ended up only in 46th position of 61 entries due to very very good competitors and some bad luck with my exo6 could only finish 1 of my qualifier heats and 2 of my finals, but this how it is. next time i will be back in the A's
