KF2 wishbone options
 

Just got the KF2 and not even run it yet but looking at setup sheets and tuning options and noticed a lot of people are running the arms reversed back and front and was wondering what this does?

Also see some are running the sv2 front arms, whats this changing?

It gives you the option of adjusting the track width and wheelbase of the car.

The SV2 arms are shorter, they give more high speed steering and also change the cars Ackerman.
Flipping the front arms calms the steering off power.

Remember you also have the option of both types of arms in the medium compound.

Thats great thanks. And flipping both front and rear standard arms to reverse? The best i can see it shifts the whole chassis and weight forward while keeping the standard wheelbase!

The KF2 is comes with the SV2 rear arms as standard. You can run the extra inner hole with these wishbones over the original KF items.
Additionally it lets you run the extra long wheelbase by flipping the arms
