Ae TC6 setups carpet

[West Ridge Racing]

Hi!
Just bought a Tc6 and I guess I am the only one in Sweden so far to own one.
Built it per manual and I thing the roll centre suggestions seems really funky. Very high! Is this right really?
Any suggestions on a good setup for low/medium grip carpet tracks with sorex 28? I should go for a lower roll centre right? How many dots and in what position then? Diff ride hight front and rear?
Oil and pistons front and rear? Any tips to get me started would be greatly appreciated.
