show-off? No... I just want to be competitive at the track. So, I will have no excuse if I couldn't get into A-main. I am quite happy with this setup because I don't like to fix cars. The only maintenance now is to clean the bearings and dust off the car.
I have one double a-arm suspension system on a MR02 and two systems on two MR03, if I have enough budget, I would like to buy one or two more on my other MR03. The double a-arm system really let the cars turn faster and more stable.
