The strider GMG and HGM have odd handling characteristics when driving at speed and giving steering input. It is like the Centre of gravity is not set correctly.
The Standard Strider does not have the same handling and behaves as you would expect it to.
Get into a Strider GMG or HMG.
Get up to 90Kph.
Steer left and right.

My guess is that the added mass (the gun) on top of the Strider HMG and GMG is causing this behaviour. Perhaps there should be some slight difference between the gunned and standard versions but this seems way over the top in it's current state and just looks ridiculous.
