Re: Roll Bar/Cage
 

I went to Rock Falls for a test n tune once last summer, and there was a guy in a Stealth there running 10.20's with no cage, and they didn't say anything to him.

Re: Roll Bar/Cage
 

hmmm... that almost makes me want to wait until I do get booted...

Re: Roll Bar/Cage
 

Id wait and see what times you put down. You might pull a Steve Hill and only run 12s. :D

Re: Roll Bar/Cage
 

LOL! Poor Steve! :D

Re: Roll Bar/Cage
 

What was your best time at the track? ;D

Re: Roll Bar/Cage
 

My friend with his turbo gtp got kicked off 3 times this year cause he was running faster than 11.50 with no rollbar or whatever you need to run that fast.

Re: Roll Bar/Cage
 

I'd go to the track first, then do the cage once you get kicked out. Rockfalls is very lienent on their rules on sport compact days. I put in the full certified cage for my safety, piece of mind, and the power the car made. I only exceeded the 135mph rating once (tad over 136, so not by much), but on that pass I was sideways for a good chunk of the first part of the track. Once I tech'd at rf's and brainerd the first time, they remembered the car and didn't even blink.

John still has the bender in his garage and can probably bend you up a hoop/bars to fit. I know he still has chrome moly as well. Remember that 4130 chrome moly needs to be tig welded, which is much more labor intensive and time consuming.

My next tba project will probably need a 6 point as well, but it will not be a drag car, and that is a good 5 years down the road before it will require one. Full Cages ruin street cars, rollbars are hardly noticeable when probably installed/fitted.

Re: Roll Bar/Cage
 

Yeah I hear you.

Here is my dilema. I would really like to wait to do something like this until I do get booted. But... my car is really only out and about maybe 6-7 months out of the year before it's thrown into storage for the winter. When it's nice out, I like to be able to enjoy it. So now, while it's in storage, is an ideal time to get any of these bigger things done, rather then doing it in the summer when I could be enjoying it.

That's my dilema. But right now I am leaning towards just waiting until I do get kicked off because it is a fairly permanent mod. And I think I oughta just wait until I know I absolutely need it.

Josh, did you guys build the one for your stealth with that bender? It was real nice. I'm really leaning towards getting one built, rather then a bolt in kit, because I think a custom bent one would be able to fit a lot smoother/cleaner, and be able to be closer to exactly what I want.

Re: Roll Bar/Cage
 

14 something :) Making maybe 200whp, never dynoing and being mostly stock. Never went to the track with the 20g.

Re: Roll Bar/Cage
 

Mine fit qell for me, but the main hoop had to be a bit forward because of how clsoe to the steering wheel i sit. I went in a few different times for jesse to measure me and figure out where the doorbar and hoop and harness bars all went.

Re: Roll Bar/Cage
 

My Main hoop was bent with there bender. I got the hoop and the straight bars and welded it in myself. John even borrowed me his old tubing notcher.

A 6 Pt with swing outs would be nice in a street car. I really like how safe I feel in my car just driving around.

Re: Roll Bar/Cage
 

RF is getting a lot tougher these days, every year they are getting worse.
But its up to you, If i had your setup I would put the cage in, you should be passing 11.49 all day maybe 3-4 passes till u hit it.

Re: Roll Bar/Cage
 

They yelled at Jet for running 12.0s a few years ago.

Re: Roll Bar/Cage
 

PM for pricing on a main hoop if you want one. I have 1 5/8" .083 chrome moly or 1 3/4" .083 chrome moly and I might have some 1 3/4 .125 mild steel.

The 1 3/4" pipe either mild steel or chrome moly is used for your 5/6 point roll bars. The kits they sell are normally called 8 points because they include the "d" bars which are only used for the 8 point roll cage, you can install them but they are not need to be legal for NHRA/IHRA.

And the 1 5/8" either mild steel or chrome moly is used for the 8 point roll cage, the cage encloses the driver where the roll bar does not.

And welding chrome moly for NHRA you need to use a TIG welder on any chrome moly or chrome moly mild steel joint, and you should use ER70s-2 welding rod, and DO NOT stress relieve the welds. You can still use a MIG welder for welding the 6 x 6 plates to the chassis but for the plate to the pipe you need to TIG.

Re: Roll Bar/Cage
 

Yep, I ran four 12.0x's and they came and talked to me three times. I finally told him the goal of my day there was to get booted! I never did quite make it that day, ran a 12.009 though.

Brandon, just go to Iowa and don't worry about a cage. I was running mid 11's down there and they never said a thing and I don't have a cage in. MUCH better traction than RF too.

Re: Roll Bar/Cage
 

Yeah, that was built with that bender and dies we have still.

John, do you have pictures of Jesse's 6 point rollbar? I know that sucker fit REALLY nice. Everytime John does a cage, he gets it tighter and tighter fitting. Plus, with a few measurements, the main hoop, cross bar, and side bars can be fitted easily to your size (if you had a buddy welding it in, construction would be easy. For some reason, I thought you had a friend that welded).

Anywho, safety equipment is really nice to have, gives you a piece of mind when traveling at high rates of speed, and stiffens the chassis.

Re: Roll Bar/Cage
 

Sorry for a little thread jack here... How much change in the chassis stiffness is noticed between a 4pt and 6pt?

Re: Roll Bar/Cage
 

I noticed a BIG difference once my setup was installed..stiff yes, but also feels safe, and can corner a bit better too.

Re: Roll Bar/Cage
 

I will dig up some pics and post them later tonight. A 6 point vs a 4 point harness bar, there would be a little difference as long as you had the door bars installed/welded in.
