[vrooom]

I tried few various setup sheet for losi 22, from likes of dustin evan, darren bloomfield, etc all of them have lot of bump steers.

what gives??

Is lot of bump steer good for this car tlr 22?

I took bit of my time to get rid of bump steer.

my front end setup is

0 shim on inside hole, 2mm shim on castor hub.
0 degrees castor hub, 25 degrees kickup.
0 degrees toe in.
spacer in front of castor block, 2mm shim on top of castor block.
0 shim on steering block.
-1 degrees camber.
shock in middle top/bottom.

That got rid of bump steer.

Why others has so much bump steer?
