Can't say it's detail but that's what I 've found:
1. The car ran so well the first time that I have given up playing with my modified MR02 AE86 from then on, which I had been playing with for more than 3 years.
2. I don't have to worry about changing the T plates to adjust the car's characteristics in centering force after rolling or when it breaks or gets worn out. (Plastic T plates are durable.)
3. I believe the oil damper shocks (with oil & pistons inside), which absorb vibration in a more linear way, give the rear a better grip than the conventional friction damper plates.
