RE: Throttle Understeer issue
Hi,
I had the M-04M before with Alfa Romeo body. I had used Tamiya Fl coated shocks on it. The steering of this car is very sensitive but very hard to control. The front dampers are very slanted and bounce back slowly once they dropped. Therefore, you get lots of steering while exiting corners, the feeling is like the back chasing the front.
If you experience understeer on throttle, you can use harder rear springs, lower front ride height, use thicker grease for the gear diff. I assume you have a stock kit.
Thx
