Question for you guys. I am building an EP'ish 914, and have a low front hoop on my cage. I read the rules, and I do clear the main hoop horizontal height of 2" below the main hoop, but I barely clear the diagonal.

SCCA states you need to be 2" below, and also below a plane that is drawn from the main hoop to the front hoop. How do you guys fit!? I've seen some pics and it doesn't seem like anyone really clears that part of the rules. (IMG:style_emoticons/default/confused24.gif)

I have my seat pretty low already, sooo.... any suggestions? or you can PM with your "cheater advice" (IMG:style_emoticons/default/happy11.gif)

I'm slammed to the floor already with a yucky aluminum seat and have it tilted as well. I wonder how strict the rules are. I do fit, but it's soooo close, I hope I don't get DQ'd or anything when tech'd.

Weld another section of bar on top of your hoop.

Is that legal? I'm curious about that one. I'm sure I will fit, but I really like my Sparco seat, and I feel better using that with a HANS than with an aluminum seat. That's the only reason why I would need more clearance.

Show me some pics. You are not much talled than me.

YOu probably need to remove the cross member where the seat normally sits.

Brad,

There's a new floor pan in there, so the crossmember is gone.

I don't have any pics here at work, so no help there. I have the seat mounted on a custom mount right to the floor, maybe less than 1cm high. I think I might be fine.

The main hoop is right at the height of the stock roll hoop, which I like since I don't like a tall main hoop as it's funky looking. (looks are important! (IMG:style_emoticons/default/clap56.gif) )

I'll play around with the mounting this week to see what I can do.

If you're going to run SCCA, do not scab on a piece to make your main hoop higher, you will not pass tech, if the tech inspector knows the most recent cage developments.

I struggled with this a while ago. Here's what I had to do:

Main hoop is mounted over the weld flange on the targa bar, but against the top corner of the targa bar thing. That targa hoop is not flat, so the main hoop sits on the top corner only in the middle and gains a bit of clearance towards the edges.

I had to ditch the sweet FIA-type seat... broke my heart... and use a crappy aluminum seat (sounds like you already did that). 20 degree layback and I laid it back even more.

Then I had to adjust the height and location of my front hoop to get my helmet under the imaginary line between the two hoops.

The SCCA is serious about this rule. Eric Madsen got told to fix it before the next session during last year's runoffs.

I can take some pics if you're interested.

Kevin,

Thanks for the tip. I got my redneck aluminum seat to fit me in the car just fine, with some room to spare. Just gotta squish down a tiny bit, and I can still remove some butt padding. I just wanted to see what others did for some ideas.

Boo hoo, I had to get rid of my pretty Sparco Pro 2000 and Recaro SPG. Looks like one of those is going back in the 993, which is a good thing.

I would assume that SCCA would not allow the extra piece up top. I don't find it safe anyways, plus it will look like (IMG:style_emoticons/default/stromberg.gif)

A pic would be nice!

Yeah, I couldn't get the fancy seat to work... there's a corner under your a@# which raises the seat as you rotate it back. The alum redneck seat doesn't have that, so when you rotate the seat it doesn't get taller.

Tom Burdge (blue and yellow car) has a scab, but, he also has a high-front hoop cage.

Eric Madsen's car (black and white) is also pictured.

Kevin,

Thanks for the pics. My main hoop is about as high as Erik's. The front hoop is pretty high as well on my car. I will take some current pics today when I get home of the mounted seat, as well as other portions of the cage. I'm sure I'm fine, but looking for a few other ways to get lower, or legal.

Your front hoop looks to be close to the height of mine. The main hoop is lower for sure. It will be a challenge to get low enough... depending on your body height. I feel like I'm on the edge and my main hoop is at least 1.5" higher than yours.... like I said, I'm on top of that flange, but back a little further. I've got the main hoop welded to the flange and to the targa bar.

And I forgot to mention... that kirkey in the pic was my second seat. I ran that for a while after cutting the side supports. I switched to a Kirkey road racing seat, 20 degree layback and it's better, but still not as nice as a Momo or Sparco. So, it took me 3 seats to get an acceptable solution.

I'm 5'10" +/- 0.5". I'm right on the edge, I just checked last night again. I should actually check with my driver's suit on too.

Terrance,

First let me say that I think the rule is stupid, but you're going to need another side bar.

From the GCR:

18.6.3 Side Protection - Open and Closed Automobiles
a. 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. Additional tubing may be added. NASCAR-style door
bars are recommended.


The problem is that you need a diagonal tube below the horizontal tube and your is not.

I forgot to mention... I had to adjust the height of my steering wheel to get it within that imaginary diagonal line between the main and front hoops.

WHAT? That's one confusing rule!

So, I guess the steering wheel needs to clear the imaginary line as well? Geeze... Well, atleast I may not use that wheel and be going with a smaller sports racer wheel instead.

Kevin,

I found another part in the rule.

18.6, top of page 113:

Open top automobiles without a windshield, and with a low front hoop design:

a. Low front hoops shall be cowl height, or at a minimum, a straight line drawn from the top of the main hoop to the top of the front hoop shall pass over the driver's hemlet

Ok, I have read this rule, and always thought that no matter what, you have to fit under this imaginary line. But, since my front hoop exceeds the cowl height, then I don't have to fit under the line, and just meet the 2" rule of the main hoop.

Am I reading this right? This might not be the place to ask this, I should be posting on the SCCA forums, but wanted to run this by you.


Oh yeah, and the door bars, it sounds right, and is a new rule. my cage was built to the 2005 rules, so I can have it added easily.
