before my T4 I had T3 2012 with the top bumper touching the bulkheads and during a not very hard crash, the topdeck broke.
Maybe on my BD5 the main chassis never broke but was tweaked?
I don't know what is the best, to touch or not the bulkheads?
The T3'12, the brace doesn't quite touch, only in an impact where it helps to even out the force of the impact.
With the T4 as it is (similar to Tamiya also) in a big front impact the bumper braces (upper and lower) will be bent up and back in the impact. As they do so the front of the chassis is exposed to impact.
Most of the time your right, it won't matter, but I have seen chassis crack and split from front impacts on other cars.
I'd rather not take the risk on some of the high speed asphalt tracks I go to.
If you only do blinky on carpet you're probably not going to get the impact speeds to do the damage.
