Chassis building to a Spec.
« on: May 30, 2013, 02:21:32 PM »
As I read some of the chassis being built or modified, I don't see a reference to a SFI spec. or possibly another standard. Am I mistaken or are there a good percentage of builds that never get inspected? Is it only sanction tracks that require a current chassis cert. ? I would think even a non-sanctioned contest should have to meet some requirement for insurance reasons. Just curious. George

If nothing else I would think you would want to get it inspected just for your own piece of mind?

Can't tell you on the majority of guys out there but if its slow enough, then obviously it doesn't need a chassis inspection which is why you see the flathead guys tend to run whatever they want and keep it much more 50s themed.

My frame is done to 2.4C sfi spec and the book was really the only "blueprint" I had.  Cacklecars don't build to spec other than what is period correct and more often than not it seems a lot of the local nostalgia races have little tech.  Very very few cars comply 100% with the NHRA rulebook but most at least adhere to the chassis spec if they are actually going to be raced.

IMO you should get as close  to spec for car your bui9lding as possible. My new chassis is built to sfi 2.2c which means it should be good for about anything I want to to with it.Plus if I got in bind and had to sell it I should be able to get more for car that can be ceritified.

 Now if your building a restoration show car that another deal .IM a race car thats not raced is like owning a brothel and going without,makes no sense

I am racing a FED with a current 6.0 certification. It was built to SFI 2.2B . Now a 2.4C. It might meet the 2.2C spec. but I'm real sure we won't be running in the 5s.

LOL!  ;D

I've always felt that way about the cackle cars . . . I love looking at them but not to be able to use it for its original intended purpose is a deal breaker.  I could never own one, whats the point in looking but not "touching"  ;)
