When the traction is way up the car is great at the few bigger races we have but when it's down or medium traction the mugen is superior at our track. Believe me I don't like to throw in the towel but I have spent so much time, money and effort and I'm going backwards.
I was suggesting, in my last post, that you should focus on building the shocks properly.
First: Check to see, if, the shocks are leaking. You may have dirty, torn orings and or scratched shock shafts. The plastic shock shaft guides may also be fouled. If, so, rebuild with fresh parts. Leaking shocks can cause your car's handling to be inconsistent.
Second: Make sure the shocks are the proper length - front and rear.
* Note all 4 shocks don't need to be the same length. Just make sure they're equal left to right. The rear can be longer than the front, but not the other way around.
Third: make sure the shock is free of air bubbles before putting the bladder and cap on. Bleed the shocks so that the shafts push out at the same speed and reach the same distance.
Once you've done these things, I think, you'll find your car behaving more like you want.
