Traction arms, best way to adjust?

Recommended Posts

Thinking of putting some adjustable rear traction arms into a silvia for supersprints and was wondering how to adjust them to gain more grip in the rear end? Also is there a way of monotoring how much there adjusted as I'am fairly sure most alignment shops don't adjust rear castor etc?

depends on the height of the car.

 

best start point is to get the stock length of the camber and traction arms. then measure the camber arms on the car (they will be xx longer) then lengthen the traction arms half that amount.

take the shock out then lift the wheel up and down through its on road range of movement. Lengthen or shorten the front upper arm to achieve the toe change you are after. You can make the car have static toe in for stability and then return to 0 toe under acceleration squat or you can have it remain at the same toe through the entire travel or whatever takes your fancy. All trial and error for what you like.

Such a big hassle^

 

Just make them 5mm longer then stock. Given that you've not gonna hardcore on ride height, like just touching the tyre.

very interesting! iv always wanted to know how to adjust mine. Tire shops have'nt got a clue.

 

Basic add 5mm more than stock.

Advanced test by removing shock and note down alignment changes.
