I'm very impressed, the only damage all day was a bearing from the steering rack (single rear bearing, MR84RS). It was enough to allow the rack to move 1mm between the bearings (picture below). Once the bearing was replaced, it was back to it's original tolerances. So it might be a good idea to carry a few spare in your pit box.

Before the last round of qualifying, I finally got into the flow of the track and managed to put down 2 tq runs (ran blinky settings in boosted and blinky 17.5 classes). In my boosted final, I made a big error on the first lap putting me in 3rd, but got back out front about halfway through the race. In my blinky final, the car was very good, I actually beat my tq time by a lap.

Setup-wise I didn't change much from my setup last week, just changed the shock settings to front A-4.2 B-1.6 and rear A-4.8 B-1.6, and put 0.5mm spacers under the rear arms. End result was a fairly aggressive, easy to drive car.

What kind of fan/heat sinks have people been using? I was trying a Yeah racing heat sink/fan mount, but had some issues with it popping off.
