Help! my b4 grip rolls

[xray011]

So i bought a second hand ftb4,mint con.ran it last night at Tamworth(carpet).with new tyres on (Terrabyte mini pins).First off i love my buggy but at the moment its handling like a pan car,apart from the fact it rolls over if i go to fast in the corners.I moved theshocks,changed springs but still rolled over.Anyone got a carpet setup?I am a buggy newbie so a lot to learn.on the buggy now is
front springs blue
rear springs silver
both shocks inner top holes
2deg camber
10.5 motor on a spx
terrabyte mini pins with soft inserts(could be too soft really)
Cheers
Alan
