2WD Newbie needs advice.

[Shaun 'TheSheep' Atkinson]

Iam going to giving 2WD a go this year as the more i watch them etc...i want one!
I'm not new to off road altogether i currently race 4WD at Nationals and off road masters, i'm an F3 so average ability. I am getting my mitts on a econg hand B4, and obviously never run a 2WD or an associated car, i just wondered if anybody could share any handy tips/info on the car, setups, upgrades etc
Anything would be apreciated

Cheers
Shaun.
