My favorite new parts are the new slipper, the alloy center axles with blades, and the camberlink mounts.
The blades will help to reduce wear on the rear outdrive of the slipper, which is maybe the biggest part of the car which wears.
The slipper is no more a doubleslipper, which means for me split slipperaction for the rear and the front (? I'm not sure about that). Should give more traction IMO.
Camberlink mounts, will make the most change IMO, I can lower the front rollcenter!!
--> =STEERING, whoop!
The shock caps with bleeding screws will be the same like in the new coming 2wd. Maybe a bit easier to make, but I got no problem so far...
