Im curious what make and type Slicks you run?
I'm also racing this Sunday on MIO.
My setup is almost the same as yours Paul. I run 3 deg. rear toe in. More makes the car to twitchy for my liking.
I do have the 64 gram bulkhead, haven't tested it yet. I do run a 8-racing shocktower with the 26 gram camber mount (
KLIK
That does help the on power grip.
At first didn't notice your 6.5 motor. I run an 8.5 @ MIO. tested a 7.5 wich will work but be a hand full.
I think your 6.5 motor is to blame for the lack of steering on power
