Alright question and hopefully not derailing but theres lot of interesting talk in here about arm length.
So .....
Looking at that Dax front end picture it seems like the kingpin is moved closer to the arm hinge pin vs what the stock C' probably would be.
Buggies and stadium trucks kingpins are out farther then the hing pin so to me its short arm.
4wd and Touring cars have the hinge pin located farther out then the king pin ....
Why? I know 4wd has to clear the front cvd and all that but what is the tuning/geometry reason? Is it just the difference in the vehicles or could the 4wd hingepin/kingpin geometry work on a 2wd or vice versa?
