Hi Shaun,

 

The change has not come to the rollover protection itself (or in reality the categories as the separation between Modified production and Modified Specialist Production is just for consistency with the roadgoing equivalent categories). The change is that useof these categories is merely recommended at present - we can ignore them and we have but they will become compulsory from 2010. Hence this means that we have to align all of our classes 1-6 against whether they fit into Roadgoing Specialist Production cars (Classes 1-2 clearly fit here) and Modified Specialist production Cars (Classes 3-6 given our curent List 1b tyre choice). My understanding is that the rollover requirements differ between the two categories (I haven't got my Blue Book with me here) and the FIA bar+petty strut does not comply for Modified Specialist Production Cars. Quite a few other things are also tied up with these categories which is why this simple looking change has quite a knock-on effect - some of which we have spotted already but there may be others.

 

Hope this helps,

 

Brian

Brian - yes that makes sense. I hadn't twigged the "use of categories" recommended vs. mandatory bit.

I still think that an FIA bar + petty strut will comply but I guess that needs clarification.

Cheers.
