So I received my MR03-S TS020 today, changed to 9t pinion and took it out for a test drive.

The car is a tad slower than my 458 probably from the heavier body, but the car drives like 10x better in terms of straight line stability.. .. and does not get caught under the track marker dots as the body rides higher off the ground.

Anyway I was surprised to see such a big improvement from the longer wheel base and thicker rear tires even within its tiny form factor.

Edit: Actually it appears the body's downforce gives it the additional stability too. Car drove like a wild horse without it..
