Here is how we did mine in my 70 Challenger. Just certed for 7:50 a couple of weeks ago. We thought about angling the main hoop to follow the side window angle but it was a little to much of angle for our liking.

O-K, you have your roll cage in and it is certified for 8.50 and it is a full bodied car. Does it need a window net ? I say yes, but our cage builder says no, it doesn't need one. Who is right?







Quote:

6:3 WINDOW NET
An SFI 27.1 ribbon-type or mesh-type window net is mandatory on
any full-bodied car required by the rules to have a roll cage.




as usual it's a gray area. if the car is REQUIRED to have a cage then it is REQUIRED to have a net. so what happens if you're running a 10.50 car with a cage? it's not required (with unaltered floor/firewall) so even though it has a cage i don't see where it should have to have a net.

just like the stories of people running an expired harness in a class not required to have a harness.

i've heard of people getting bounced because the harness is expired...gimme a break. it's not ok to use a 25 month old, tugboat towing worthy three inch five point racing harness that there's absolutely nothing wrong with except greed but it IS ok to use a 40 year old two inch lap belt




I know guys that cut the cert tag off... if its not
required and they are fine... my Rampage has a full
cage but I will run 10.0 or slower so I sure hope
I dont need a net(dont want one... its a street car)





If it has a cage it needs a net.

where does it say that? it says if the car is required to have a cage it needs a net. what if the car is not required to have a cage but has one? just as i'm typing this i thought of a racer i know (very successful i might add) that has a 11.20 second A body that i'm almost certain has a cage in it but no net, he's run a lot of different tracks that way.

I'm not planning on a net... to my understanding its
just required sub 10.0 which at that point requires
a full cage

Many tracks may not care but when we were building my car I found it in the rulebook, I'll have to find it but it's in there. I asked a couple chassis builders first and they told me the same thing, so I looked and it was in there.

EDIT: I'll look and post it but it won't be tonight, got a date...

Window nets are required for 9.99 and quicker.

As for the main hoop question.The seat can be no more than 6" in front of the main hoop.The main hoop can be laid back at no more than 20*.Your helmet must rest below the main hoop a minimum of 1".The drivers position dictates the hoop position.Hope this answers your question.These are right from SFI specs.

You planning on using my old throttle stop
