Hmmm, interesting.
Given the developments the UK team have been working on this represents a possible step backwards. The move to MP7.5-style pivot pin holders mean there is no option to adjust the roll centre of the car. The UK team were raising the XR's aluminium holders up from the chassis some 3-4mm!!! From what both they, and others who made these adjustments, have said the handling was much improved by this.
Also, I dread to think what will happen to the steering servo when it gets wet and muddy. Who elso has experienced the build-up of mud around the steering servo area due to the wheels forcing it under the bodyshell and through the cutouts for the steering linkages?
Nice to see they have kept the front pivot balls though.
