After looking at the problems associated with the lack of adjustment on the 4 wheel drive vehicles, especially noticeable when the vehicle has been lowered, we decided to look for the best solution. It was about this time that owners were starting to report in Europe that they were experiencing the rear control arms snapping.
Rather than looking at an eccentric bush replacement, we decided to re-engineer the rear control arm to what it should have been in the first place.
We started by adding the means of adjustment, then added strengthening, especially as we appreciate that many of our customers may be using their vehicles on the track. Then we had polyurethane bushes made because they offer far better characteristics. After many months of rigorous testing we are now confident we have the perfect solution.
If you ignore the obvious benefits of reducing uneven tire wear and improving the tire surface contact area, the seat of the pants ride is far better. If you just return the car to the OEM original geometry settings, you find that the tram lining feel disappears and the turn in is far crisper. Of course, if you are willing to experiment with the settings to maximise any other modifications on your car, then this set up is for you. You may be interested to know that the ‘Le Mans’ or ‘S-lines’ that come with the -20mm suspension also benefit from these arms in a big way.
As we continually monitor and evaluate our products we have recently revised the production of these rear tie bars with the addition of a corrosion resistant powder coating process, to ensure the maximum longevity even in the worst environments.
