how's this going to work with OSS basically mergering in with SBI. Who's rules are you guys going to follow? From the schedule it looks like they're all but one ( Biloxi) Sbi races which would mean that SBi rules apply?

hence superstock rules are governed by SBI and DW's new boat is going to be legal?

Why not adopt x-cat and move in a more unified way?

[XtremeRacing]

Dave ,

Not really sure if there is any differance in the OSS and SBI stock class rules, but I'm sure Ryan could answer that better, he is more fimilar with the rule then me. I know we took a look at all the class at earlier in the yr when we merged and pretty sure they were the same.

[skaterdave]

well reading what you posted for SBI and what Ryan posted for OSS the main difference is the tunnel width.

So, it seems that SBI rules that the new DW and x-cat type boats would be legal, which would seem to be the way to go to opening up the class for more competition???????

My suggestion would be to invite any and all who wish to race. If there is truly an unfair advantage, there are ways of dealing with it.
