I guess it all depends on the chassis and the body. "thumbsup""thumbsup".

Surely having a longer wheel base , you need longer drive shafts ?

There's a few options, Junfac makes a shaft you can get 140mm out of, Punisher shafts, Mips with various configurations (Wraith, Summit)"thumbsup"

I'd like to have longer front links
so the steering servo is more forward like yours Daniel"thumbsup" ,
of my Pro-Line tuber cage...

How do you make them is it solid alloy bar that you drill
and tap a 3mm thread into..

Sean.

Exactly, I had the material (Solid Rod) and cut it to length. Sent it off to Crawling Calvin and he did the rest. I had him do the upper links to 3mm and the lowers are hogged to 4mm.

As far as Drive shafts, I used the MIP replacment Wraith units. Perfect length for my build. And I have to admit I have destroyed Junfac shafts in the past. I have always run MIP in the past. The one time I swayed away I got shafted. :lmao:

Calvin is a Great Guy, he will do you right. Let Calvin know I have more of the material I used. If you figure out your measurments he and I can work it out from this end. I am sure you would rather not ship back and forth from Ireland. Let me know if I can help out Sean.
