SX3 Setup question - weight in the wet?

[dibble34]

Hi all

I am running the brass lipo tray holders and the trishbit bits centre weight as per Simon moss setup found here http://www.oople.com/forums/attachme...2&d=1309335150

What I am finding at TORCH astro track is that in the wet it is a little tail happy. Almost too much rotation?

My questions are

Should I remove the trishbits weight and just run the saddle holders? Would this help stop the car rotating so much?

Would it help to remove the rear roll bar? Does that give the rear more grip?

In the dry this setup works really well for me, but it was a handful in the wet!

Any assistance greatfully received
