Gen 4 suspension lift

My spacers from Uys arrived this morning. I had some free time and two hours later Paddatjie was back on her wheels with the spacers installed and the wheel alignment done.
The installation of the spacers is actually very easy. To install the front ones you have to remove the battery box on the left side and the air box on the right. With the wheels removed undo the bottom shock bolt and remove. Then undo the two upper control arm bolts and remove. Compress the spring with a spring compressor. Undo the 3 nuts that holds the top of the strut in place. Now simply remove the complete strut assembly. Bolt the spacer onto the strut and replace all the parts in the reverse order.
In the back its even easier. Remove the wheel. support the lower control arm on a trolly jack. Remove the bolt that holds the shock to the lower control arm. Remove the bolt holding the stub axle assy to the lower control arm. Now lower the control arm until the spring comes out. Place the spacer on top to the spring and do the reverse to re-assemble.
Last step is to do the wheel alignment. The camber adjusters will almost max out with the spacers in place, but they work. I was concerned that we would have to machine new adjusters with more cam lift, but the standard units works fine.
My Pajaro is driven off road 80% of the time and therefor we decoded to run it with less than standard toe. This setting will improve 4x4 driving, but reduce on-road handling. Since I will be fitting proper off road tires I will in any case not be able to exceed 140km/hour which is the max that these tires can handle, so the toe setting will be fine for me.
My settings are:
Front:
Cross camber: 0°15’
Cross castor: 0°16’
Cross SAI: 0°30’
Total toe: 0°05’
Rear:
Cross camber: -0°09’
Total toe: 0°12’
Thrust angle: 0°01’
Total lift:
Front: 50mm
Rear: 54mm
Distance from centre of wheel to wheel arch: 570mm front & back.
Now I can't wait for my 265/70-17 Cooper SST's to arrive later this week! Sunday's rocks are calling me back. Wonder how the extra 50+mm and the new tires will perform there? Ag- well, have to wait for the weekend to play...
