No, glass!
But there are ways to cure that.

How are you solving it? TA05?

Ta05 or Exotek. If you like uncommon caster angles like 5 degree, Square from Japan has nice aluminium C-hubs too.

Take it or leave it. The only other way is not to crash your car. This until Tamiya gives us finally an update of their c-hubs.

・This is an R/C 1/10 scale shaft-driven 4WD chassis assembly kit. Length: 371mm, Width: 185mm, Wheelbase: 258mm.
・The chassis is based around a 2mm thick aluminum lower deck and 6mm thick center stiffener, which give a blend of rigid pitch damping and flexible roll. The number of screws used to attach the stiffener can be changed to alter chassis rigidity.
・The lack of an upper deck lowers the chassis' center of gravity.
・A largely overhauled layout includes updated motor positions and bulkhead design.
・The motor is longitudinally mounted. Users can choose from 3 layouts (front; mid; rear) to adjust performance depending upon conditions and driving style.
・Comes with TRF super short big bore dampers.
・Motor clearance can be adjusted simply from above, for quick in-pit tweaks.
・Steering linkage components are installed directly onto the bulkhead as opposed to being attached to the chassis. This removes any effect upon chassis roll.
・Highly-efficient shaft-driven 4WD is achieved with a front direct coupling and WO universal shafts, plus a rear gear differential unit and aluminum drive shafts.
・Proven TRF418 suspension arms and TRF419 rear uprights are employed.

TBEvo07 (#42315) will offer 3 motor positions - front, mid, rear!

6mm center stiffener is attached with multiple screws which can alter to set up chassis flex.

Steering assembly is completely attached to the front bulkhead.

Seems the kit will be soon released.

Hmm, I always thought the reason you put the motor the way it is with current touring cars (perpendicular?) is to decrease the torque steer on acceleration and breaking. Now I see that the motor here is setup parallel to the shaft... Can someone explain this?

Keeps the weight close to the center and increases efficiency as there's less gearboxes. The Evo 6 had it perpendicular but the Exotek Exo 6 conversion was a popular way to get it parallel again. Torque steer essentially doesn't exist with a brushless stock motor where these cars are popular.

Torque steer comes from rotating mass. Specifically when you have the drive train all rotating in the same direction. When you have the motor perpendicular, there is one in fact torque steer. However when the motor is fit longitudinal to the drive train, it actually rotates in the opposite direction of the drive train which creates a somewhat equal amount of torque steer in the opposite direction. In other words have the motor longitudinal counters the torque steer.
