I got to drive my R5 for the first time yesterday and it was a blast. I run on med to med low bite asphalt and had the odd problem that it would randomly spin out. I am sure it is not setup right. I will have to do some more testing to figure out the problem. However I did have another issue that the rear end always wanted to swap ends in the corner. I tried double pink Jaco Prisms all around then used lilacs in the front, then tried lilac front and magenta rear. It SHOULD have been pushing like crazy from too little front traction and too much rear traction, however it STILL could not take corners at any decent speed. Diff was not slipping and felt VERY smooth like it should.
Running 20 wt AE oil in both dampers, and kit springs. I tried black side springs which did not help. Ride height at 4-5.5 mm as the track surface is pitted.
