Has anyone here added door bars to their bolt-in Autopower 4pt. bar to make it a 6pt. If so does enable you to step up from 150mph to 175mph?
The only list of rules I've been able to find online is this one: http://www.ecta-lsr.com/?page_id=21
I know there are far more rules. Does anyone here have a link to an actual rule book? Or do I have to buy one?

How would adding door bars turn the cage into a 6 point? :? :?

"III-2 ROLL BAR & ROLL CAGE: All cars in competition over 135 MPH, must be equipped with a roll bar or roll cage structure. All closed cars between 135 and 150 MPH must have a 4 point roll bar. All closed cars between 150 and 175 MPH must have a 6 - point roll bar. All closed cars over 175 MPH must have a full roll cage. All open cars are advanced one bar / cage category over closed cars. Any individual wishing to enter a vehicle which deviates from these rules MUST contact the ECTA 45 days before the event for approval."
Am I mistaken? I've been under the impression that the number of points the bar contact the floor= Xpt. Bar.

So this is not an example of a 6pt. bar?

Better buy the rule book

A six point cage is a full four point cage plus the two back braces. All the supplementary bars and gussets will also be required. As Glen says, get a rule book.

That will get you up to 175 at maxton But its your but in the seat+ next year all 175+mph cars will have head restrants.So for $100. you can have a cage good to 200 mph over what you have.

That roll bar is not legal at any SCTA / BNI event.

Well, I sent in my check for the rulebook... We'll see just how much safety/speed I can afford.

150-175MPH, 6 point Roll Bar for closed cars Section 3.B.

If you are using a bolt in side bars, it needs to have grade 8 bolts and nuts...nylock nuts are not grade 8.
-
Mr Timney is WRONG!
Grade 8 Nylock Self Locking nuts are indeed available.
For example, check out NutsandBolts.com along with MANY other suppliers.
-
I am not sure about Grade 8 Nylocks, but I am positive they make Grade 8 TopLock locking nuts.
I will check my bolt bin and see about Grade 8 locking nut choices..
Fastenal shows both available,,, hmm I did not know that !!!!
Guess we are all correct now,,

How do they note that on the product?

Answered my own question, looked up nutsandbolts.com. Good prices! I have bought grade 8 hardware from the same aircraft supplier for 30+ years and always used wavy thread lock nuts...I guess I should look around once and a while...LOL! Thanks for the update.
Attn: Aircraft folks...is the gold color plating on grade 8 a required aviation standard? I just saw black oxide grade 8 bolts from a Case farm equipment dealer...never saw it that way.
