For all of the RFBs, there is a cure for LFB.....amputation!

LFB really comes into it's own on FWD cars
I think that Timo Makkinen in the minis and Erik
"strong on the roof"
Carlsson were the main culprits.
with an underpowered FWD you need to keep the engine
on the cam as much
a possible, so have the throttle buried in the carpet
at all times.
In a FWD a quick good hard jab on the stoppers with
the left foot during
turn in will throw the back end of the car out, as the
engine tends to
overcome the front brakes (at WOT), but the rear
un-driven wheels try
and lock at least a bit, especially on gravel (and
especially with
standard mini brakes)
All this and you don't even have to let go of the
wheel to grab for the
Turning Brake (Emergency Brake "over here").
As i remember the handbrake on saabs used to work on
the front wheels,
just to make things difficult.
a friend of mine parked his dad's new 900 16v turbo in
a fence post
whilst trying to impress in the snow.
he was used to his battered vauxhall nova with the
rear wheel hand brake.
needles to say he did not "impress" anyone, including
the old man.

I"m sure that you've all seen this vid, but watch the
guy's feet half
way through
