SST is going to happen! They just finished building truck number 22. I think the plan is to have 30 trucks built and ready by the first race of the year in Phoenix. If Robby & SST did not think they had enough drivers to fill the seats, I dont think they would be building as many trucks as they are. Plus they have a huge TV contract with NBC. Not one other off-road racing series has the TV contract that SST does.
Regarding who is racing SST. I do know 3 drivers have been announced and I know of 3 more, which I am not at liberty to say as I know they are going to be releasing these drivers names in PR. So far Robby is driving one, NASCAR truck series & Class 1 off-road racer Justin Lofton is driving one and Indy cars Arie Luyendyk Jr has announced his plans to race. A few former Mickey Thompson racers are supposedly signed up and some current short course drivers are also on the list. I will say one former Chopper builder who dabbles in off-road racing is said to be signed up too! But this is all I will say right now about who might be signed up. Heard Travis Pastrana was very close to running the series, but with him signing a full time NationWide NASCAR deal with Roush it squashed any chance of that. Who knows maybe Travis can make a single race appearance?
Now loosing the UTV's is a bummer as I thought as so did RG apparently that the UTV's were the perfect replacement for the Ultalites that used to race Mickey Thompson. I get that SST was looking to get UTV manufactures involved and am surprised they did not jump aboard. Maybe they could have ran this part of the series without manufacture support, but I do know having their support was part of the original plan.
Bringing the Super Buggy's in to replace them is a perfect replacement as buggy's are already racing in other series and they have already raced in Stadium events so we all know it works, and they put on IMO as good if not better of a show.
Just go back and find some you-tube footage of the Mickey Thompson super buggy's and you will see they did great in this type of venue.
