Did you put those little button head screws in the steering knuckles?

I didn't have this problem with mine at all but I put those little screws in which stop the knuckle from traveling far enough to do this.

It's the only thing I can think of that might be causing this.

Interesting. I know the new front gearboxes raise diff input. I would contact Tekno.

I . Going to take the front clip off again today and reinstall it . I was just thinking if it only sits a few mm then it would be perfect. What was their reasoning to raise diff input?

Bumping this thread after 2yr 3mo since the last post as I'm still actively driving and enjoying my NB48 2.0! Only recently became aware of the updated brake cams that came out all the way back in November 2021 when the NT48 2.0 came out, which is also the same set used on the current 2.1 buggy. Saw a review on Amain praising them as a great upgrade for the buggy 2.0 people, but couldn't tell for sure what the change was. I've got them now and figured I'd share.
TKR9215 is the old design, TKR9215B is the newer.

I've only got 1 day at the track on them, but it's a lot better. They engage much sooner in the swing of the wire levers that the linkages pull on, making the engagement start a lot closer to when the levers are squared up parallel to one another, whereas the old cams would swing like 45 degrees to work, which kinda diminishes the leverage of the servo horn and got worse with wear.
