#1. i.m.o. trimmed tires are used for the stability of the car in jumps. the stock tires are too thick that after the jump, it may bounce out of the tracks.
also you can calibrate the speed and control of your car with the trimmed tires. mind you that a .1 change in the tire diameter would increase or decrease the car's performance.
#2. I always tell my self to always give the benefit of the doubt so my answer would be no. However the chances that they may not cheat is like... maybe a snake eyes in a game of dice?
#3. brake set?
calling sir ivy, sir aero.
check this threadthere are also breaksets being sold at the moment somewhere at harisson plaza you just have to go there and find out.. before it goes out of stock again
other options would be online buying
#4. aside from the gray brake set, you can use the brakes from the sliding damper as for an alternative. you can buy them cheap from people who doesn't use them instead of buying a new one (history tells that they used the black brake set from the sliding damper before the gray become a trend so... the black may is still effective)
so there you have it... you just have to tweak the set up and see for your self which is better and compete with it!
