***2. IT - Questioning why the side protection rules are different in GT and Production (Dewhurst). The IT roll cages are based on the rules of Showroom Stock and, to some extent, Touring. The door bars allowed in IT are compliant in both Production and GT.***
"The door bars allowed in IT are compliant in both Production and GT." This statement my friends is a bunch of crap.
The SS/IT & Touring roll cage side protection rule is: Two (2) side tubes connecting the front and rear hoops across both door openings are mandatory. An example for SS/IT & Touring side protection could be that the mandatory upper tube is at a diagonal & the lower mandatory tube is horizontal.
The Production & GT side protection rule is: The minimum side protection shall consist of a horizontal side tube connecting the front and rear hoops across both the door openings. Additionally there shall also be either a diagonal tube from the front hoop to the rear hoop bisecting the door opening BELOW the horizontal side tube, or not less than two (2) horizontal side tubes.
The bunch of crap forwarded in the Fastrack is that per the rules the side protection which is legal for SS/IT & Touring as I described is compliant for Production & or GT race cars is NOT A FACT. THE TWO RULES ARE ABSOLUTLY DIFFERENT AS THEY ARE WRITTEN.
Any ITAC folks care to set me straight with the above rules IF I am not correct ?
I would write a letter but what's the value when the rule making people can't read their own rules.
Just as another example crap response to a rule of the answers given in Fastrack & updated rules which are ongoing, the main hoop diagonal for Production is no longer required to be WITHIN the main hoop. This keep people happy crap versus safety needs to go.
While I'm on a roll (notice I didn't say rant) there is nothing new about the roll cage padding. In years past SIF 45.1 roll cage pad was/is required & it says nothing about a lable or marking required. I understand I would need to have proof that the pad is SFI 45.1 OR FIA 8857-2001.
With the response that bushing material is Spherical bearings the only thing I have to offer is that the ITAC/CRB/BoD has a short memory & has forgotten why Production cars cost is totally out of control & also why they the CRB/BoD initiated LP/Restricted Suspension Production cars.
Still rolling (NAW, THIS IS RANT), the CRB/BoD is going to play follow the other racing groups (note I didn't say follow the leader) with the helmet restraint system. They also came along following other racing groups with the recomended right side safety net. You ask why the right side safety net is recomended, the answer is simple, the HANS will not reduce laterial loads of the helmet. A secondary devise is required.
This rolling rant is provided by David who bought a new car to build/replace his totaled ITA/7 Rx-7 which is stuffed in one side of the garage while a Spec Miata is being built in the other side of the garage.
