Are you certain the tires aren't hitting the body at maximum steering angle?

That is most likely the CVD's operating outside of their intended range of motion. Turn down your Dual Rate of EPA on your transmitter.

Do you notice anything unusual on the track?

check and see if the wheels are rubbing against the screws that hold the bottom of the shocks into the front arms

hi there,
i have already tried those things with the car, the wheels arent rubbing, and the cvd's arent past there intended lock,i have adjusted i have the handset to only give me 50% lock and it still doers it, mainly at low speeds, i even had the wheels balanced, bought new shiney cvds, and the problem is still there :(
thanks for your help

My XXX-s didn't even shudder at 100%. But I did have to bring the total throw down to 65%. I would suggest you take it into your LHS or at a track and let them look at it.

It could be from the car having a lot of ackerman built into it(bellcranks being spaced further apart). That makes the inside wheel turn sharper than the outside wheel on the front. It will let the inside wheel flop around some when turning, doesn't hurt anything, just more annoying than anything. Might want to double check that you have your front toe set right or steering servo balance correct on your radio.
