Yeah, there was a recent change for 2024. The owner is not longer selling VP-Pro (just left over). He created his own tire line and it's made in the USA but so far only 1/8 buggy and I think 1/8 truggy coming soon. I appreciate you watching though. I'll get more content up soon :)
I'm not sure exactly what the offset is but it's the same as the Tekno RC SCT wheel. If you can find out the offset of the Tekno wheel, that will be the offset.
Hmm, I'm not having any issues with anything touching inside the wheel. I'm not sure what you mean about the HEX? The hex part normally keys into the wheel. What wheels are you using? I've used some wheels in the past that had fins on the interior that would rub against the wheel hub and ball ends. The SCT wheels from Dialed-RC Hobbies should fit perfectly on the 410.3 or the 410SL as I've used them on both. They have the same offset as the Tekno SCT wheels.
