This was a snippet from my first drive after winter. I did some debugging with regards to the ignition timing and balanced the carbs up. She ran like a dream all day.
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.
6: Remove the 2 inboard mounting bolts, try not to drop or lose the captive nuts.
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
At this point you can fit the large locking nut on the ball joint end, refit the road wheel and 4 nuts. remove the axle stands and jack from under the car. I would recommend bouncing the suspension a few times before tightening the inboard two wishbone bolts.
