Until the BRCA state 'Only cars marketed and sold as 2wd maybe used' then that's the way it will be.
Might as well open your debate (?) up to using a 2wd in a 4wd class providing the weight is right. Haven't got a 4wd?, don't race in that class....
Two sides to every story.
BTW the Xb4 in 2wd rocks!
(as do the K1's and the B44.2!)
