GT6 / Spitfire Adjustable front wishbones

There are many advantages to fitting these adjustable front wishbones to your GT6 or Spitfire.

– fully adjustable camber

– Lighter configuration

– stronger suspension with less flex

Here is the procedure for fitting these modifications

1: Park the vehicle on a flat and solid surface and chock the rear wheels, then release the handbrake.

2: Locate a suitable jack under the front main chassis rail.

3: Loosen the 4 wheel nuts about a half a turn on the corner to be removed.  Now jack the vehical to a height that will allow axel stands to be inserted under the main chassis rails.

4: remove the 4 wheel nuts and wheel.

4: If working on the left corner, turn the steering fully to the left to gain better access to the wishbone/hub.

5: Remove the wishbone-hub mounting bolt, then use a suitable ball joint breaker to separate the tapered joint as bellow.

7: remove the upper wishbone.

8: using a press or vice, (hamer and suitable sized sockets can be used) press fit the 2 inner bushes into the new wishbone, then insert the wishbone into the chassis upright.  Insert the 2 bolts  (I recommend always re-greasing and bolts removed to preserve  them.)

Do not fully tighten the inboard two bolts until the car is back resting on it’s wheel.  this helps the bushed settle in their most relaxed and natural position.

9: Insert the tapered ball joint into the front hub upright, to set the taper firmly in place it is sometimes helpful toe give the top a tap with a hammer.  this will stop the ball joint spinning while trying to tighten the securing nut on the underside
