Hi guys
I've been slowly but surely ordering and fitting ugrades to my Durga, so far I've installed front one-way, slipper and shocks plus I have a BL and LiPo setup waiting in the wings. The battery has arrived but still waiting on the charger and motor/esc combo. It's lucky I had that promotion at work recently

(also need things to do whilst my girlfriend is abroad for 4 months)
Few questions though, excuse the noobishness.
How much ground clearance should this buggy have for general offroad driving?
Are there any off-road tracks in south London? The closest I can find is Eden Park, which looks great but would take me about an hour and a half to get to by train and foot.
Is there a general 4WD buggy set-up guide anywhere? Just so I have a reference for tweaking the shocks etc.
Cheers
