I remember on the b3 there was an option of a slim rear wheel or a wide rear wheel and you could fine tune the grip level you wanted- i got the impression at the Belgium GP that they ran 4wd fronts on the rear as the grip level was high

Have to say Sleigh; in all the years I ran at tivy winter I never tried the slim rear option. was this with a losi step pin 4wd front on the rear?
