Mini 4WD Lane Change Tips

The lane change is the section that ends most runs. The car crosses between lanes on a raised bridge, and roller geometry decides whether it makes it.

Roller height is decisive

The rollers must engage the guide walls through the whole crossing. A roller set too high lets the car climb the wall; too low and it drops under the guide. This is the first thing to check.

Stagger helps the car settle

A small difference between front and rear roller width can stop the car from oscillating as it crosses. Excessive width, on the other hand, leaves nothing to guide it.

Approach speed

A car arriving too fast will lift regardless of geometry. If setup changes are not fixing it, the answer is a brake on the approach rather than more roller.

Watch it repeatedly

Run the section several times and watch closely rather than guessing from where the car ended up. The failure mode is usually visible if you look at the entry, not the exit.
