As you can see it's quite soft for a high grip track. The car does roll a little but it stays firmly on the track and despite providing a lot of steering and grip. I never experienced grip roll, even when pushed hard at the end of the straight.

If I wanted more aggressive steering I would stiffen the rear of the car with 2.7 or even 3.0 springs. I would also go to 500 oil if the track was warmer and the grip went up a level.

The upper front brace helps take a little 'Bite' out of the steering. I found that the feel was better to have more camber at the front and run the brace, than to take it off and run more conventional 1 or 1.5 deg setting.

Importantly I had a great days racing at the MiCC. Catching up with lots of friends at the track and then battling against each other on the track is a great buzz. The Tamiya TRF420 was superb all day. No breakages, no movement or tweaks and I had no worries about keeping up with the other chassis at the track. I also knew that there was more speed available. If I had banked the first qualifying round I could have pushed a lot harder in the fourth round to really explore the limits of the track, and it seems my F.D.R was still really high compared to a lot of other 17.5 racers.

The ZooRacing Wolverine was great. I had plenty of steering and stability. I had mounted the shell at the neutral position, as the TRF420 lets you move the body 2mm forward if I needed more steering. In the end I just left it where it was.

I had mounted the shell with internal rear bodyposts. Thanks to the RCMaker parts. I will cover those in a bit of detail another day. I really like rear facing bodyposts as they help reduce body-tuck. I also think that they must help the air get to the rear wing to ensure that it is more efficient.
