There's a small following for FWD buggies but on the whole, they don't seem to be that popular with the hardcore racers.
At the moment, I am practicing and racing with the Orb FF210 alongside my conventional RWD 2WD buggies.
Initial thoughts are that this buggy has immense grip in slippery conditions.
Here's a clip of Lee Martin trying out the FF210 on my home track during a LMR training session.
