Nissan 200SX Silvia and Skyline Rear Suspension Arm Guide
- 1) Toe rod
- 2) Camber arm
- 3) Traction rod
- 4) Lower arm
The above picture shows an S13 subframe, but the same rules apply to S13, S14/15, Skyline R32/33/34 and 300ZX.
The only changes between models are:
Camber arm: S13, R32 and Z32 use a different camber arm compared with S14/15 and R33/34. Function and mounting points are identical.
Toe rods: Any HICAS equipped model, will require our HICAS removal kit. This removes the HICAS rack, includes brackets to mount the toe rods and new upright bushes.
Driftworks alignment arms are required because the stock eccentric bolt adjustment doesn't have a large enough range for lowered cars. This will result in out-of-spec alignment, and in turn poor handling and tyre wear. They are also rose jointed, which replaces old, tired bushes and firms up the handling.
All Driftworks alignment arms are produced from steel, and use high quality rose joints/spherical bearings. The arms come with a LIFETIME warranty against mechanical failure (arm/weld breakage) and a 12 month warranty on bearings.
Toe is how parallel the wheels are to each other on a horizontal plane. This is the MAIN cause of excessive tyre wear (not camber as often suggested).
Toe in gives straight line stability, so it effects “drive” or “bite” when drifting/accelerating. As the wheels are pointing in they want to “push” the car forwards.
Toe out gives straight line instability, as the wheels are facing outwards they always want to “turn”. This is used to give better initial turn-in to a corner, and increased leading wheel steering angle.
As mentioned, excessive in/out toe will heavily affect tyre wear, so most road cars use near zero (parallel) toe.
Camber is a measurement in degrees of a wheel’s vertical alignment perpendicular to it’s surface. Simply speaking, 0 camber is bolt upright, negative camber leans in towards the car, positive camber leans out away from the car.
Camber is used to maintain grip levels when cornering as the cornering force a tire has is highly dependent on its angle relative to the road. By using camber, you can maintain a good contact patch with the road as the car rolls. It is also common to use negative camber on the front of a drift car to increase contact when using lots of steering lock.
Camber will affect rear tyre wear when drifting, as spinning the tyres makes wear much more pronounced. It does not affect tyre wear under normal situations anywhere near what is commonly thought. We have used up to -4 front camber with no noticeable effect to wear, it will however make “tramlining” in rutts in the roads more pronounced and lower front grip under braking and initial turn in.
The traction rod controls toe and camber in dynamic situations. What this means is when the car is moving through suspension travel. To set this correctly requires determining what you require your dynamic alignment to be, plotting of toe/camber under suspension bump/rebound and adjusting the traction rod length accordingly.
As this is highly complex and time consuming, we recommend setting the rod 10mm longer than stock for your average setup.
