Larry is right. We already have all the data we need right in front of us if only we are willing to look at it. Rotax has allowed FWB for a year now. This is the second year the FWT has allowed them. The FWT is by far the most competitive series going. And guess what, there’s no difference. If anything, the RWB karts are slightly faster. All of the dreaded comments of the differences in driving line haven’t materialized on the race track.
We don’t need to study it, there isn’t an advantage, period. If there was, you don’t think the guys in the FWT wouldn’t have switched? For those concerned about mixing the two or adding weight, I strongly ask that you come to Florida next month and watch. You will see that your concerns are unfounded.
