Can't believe it's never occured to me to put sheet metal over the side bars of a rollcage! Could enclose the outside and over the top then have an insert on the inside that matches the interior (or do it all sheetmetal like below) The insert could also me made removeable as an access panel to inspect the cage underneath. Paint the sheet metal then cover it with clear vinyl to protect it from wear...

I know AAP builds roll cages for Supras that are hidden underneath paneling. The car looks like it doesn't have a cage. It takes a lot of time and $$ though.

Who's gonna fab up the A, B pillar plastic or suede interior paneling and the interior inserts to cover everything up and make it look stock? hahaha

Technically the old JGTC i believe.

That's what i thought.

Now help me understand this.

GT300 cars (300HP) and GT500 (500HP)

so how does a Ferrari 360 that out of the factory produces far more power compete in a class limited to 300hp. I read that JGTC machines have superior aerodynamics to even FIA GT1 cars.

Are cars like the 360 still limited to 300hp or do the superior aero on the other cars + weight penalties out way the difference so the car can have more power than 300?

Speedminded.... that was not one of your better post.

I feel ashamed that you would think i haven't checked wiki and many other sources before hand.

But anyways, with this article....and the success ballast system.... im assuming (like i have all along) the GT300 designation means nothing. Is this the case?

""""GT300

Few works teams participate in GT300, so the field tends to be much more varied in terms of types of cars entered; although here, as in many European and North American events, Porsche tends to dominate with its 911 GT3 model making up the bulk of the field. The big Japanese car makers also participate in this class, as well as more exotic cars from the likes of Vemac and ASL. Since 2006, European-style GT cars have chosen to concentrate in this series, with Lamborghini leading the move from the higher division with some success, including a class win in the opening round of the 2006 season at Suzuka. Along with the standard GT cars, Shiden, a Riley Daytona Prototype car also exist in GT300 class since 2006, getting outstanding results (losing the title to RX-7 with tied points but less wins in 2006, and won the title in 2007). Until early 2000s when FWD cars were being permitted to be converted to RWD configuration, many of these such as Mitsubishi FTO and Toyota Corolla Levin AE101 competed in its original configuration.

GT300 cars are much more regulated than their GT500 counterparts, and much more closely resemble road-going versions. Chassis clips and realignments are not allowed (except the latter in the case of front-wheel drive cars), which results in a much more affordable racing experience for privateers. While engine outputs and modifications are at a lower level than the GT500 cars, the GT300 cars still post competitive times and races are very competitive.""""

Plus could run wiring to the back in it, put switches on it, or even a vent in it to allow more air flow then what's provided on the dash.

Won't know how practical it is until the cage is done but cost is 100% irrelevant when you have a pneumatic riveter and access to a metal brake and slicer. What is it, about $100 for a 4' x 10' sheet of aluminum sheet metal? It's not like I have to pay someone $100+ p/hr to make something I can fabricate myself.

If you build it right why do you have to climb over a "jungle gym"? What will covering the bars do for you? It is only going to the same height as the bars or higher if you space it over the bars.

I just don't see the point in the time spent whether you are paying someone or doing it yourself. I guess if you want to impress people looking at it then it would be worthwhile. I would rather spend my hours that I would spend doing it doing something else.

Perhaps, something more important that no one has considered are the implications for the car passing tech at the event you want to drive.

For example, I'm about 90% certain that if a car showed up to a NASA-SE event with a cage like in the Ferrari, we would not allow it to pass tech. Why?

There wouldn't be any SFI padding protecting the driver's or instructor's melons in the event of an off course excursion into a tire wall, or, God forbid, a roll over.

Maybe you have checked the rules for the sanctioning body where you want to drive the car, but the posts in this thread seem to indicate otherwise.

http://www.pegasusautoracing.com/productselection.asp?Product=2396

I've already mentioned [at least once] about making the interior panel removable for cage inspection...could easily do the same for the exterior panel too allowing a full 360° view around all the welds on the cross bars. It's really not rocket science.

The lil project car I'm building probably won't be legal in ANY competitive sanctioning body, lolol...it's just a fun 2,100-2,200lbs play car with nearly 400hp on low boost. Will make a great time attack car though, should I post the specifications of the cage they require for you? ;)

Sure it's going to enclose the "cockpit" more, it may even make it feel smaller inside but the goal is to make the interior clean and simple. Who knows, it may not look the way i want it too...that's why i want to see more pics of it to get ideas!!

I completely understand what you are doing. The enclosed cages seems more of a "oh wow damn that is SICK" kind of response on a web forum.

When I was at Fall-Line Motorsports in Chicago building Grand Am Cup M3s(now Koni Challenge) there was no time to worry about bull **** like that. There was chassis setup and engine tuning and the list goes on and on. The point of a race car is to win and most of the time function comes over form if it helps win.

I will say again, I don't see the point in wasting my own time or paying someone to do this. It certainly may look cool and get some responses on a web forum but what is the point?

Time Attack have bull**** rules for safety. I think you can run a bolt in 4 point... maybe requires a 6 point. Why don't you build the car to a class?

~looking for the race car~ **crickets**

...nope, still not a race car. I sure as hell won't let anyone drive next to my car like that let alone a couple dozen. That's what a stock body, legal brakes, non-turbo, etc. car is for. I don't have a schedule, I don't have a calender of events I have to drive in, I don't have a race team relying to feed their families with the car...nothing. It's just a safe and relatively quick play car that will occasionally see time on the track. I will have a track car but it won't be this one.

As for Time Attack, I don't care if they allow PVC pipe for a rollcage...i'm building it to the specs I feel safe in, whether its SCCA or DTM or a combination of all the best and safest things I find.

I suppose my take on the whole idea is similar to DinanM3Atl's. I don't really see the point to putting all the work into something that will ultimately only add weight and make the tech inspection process at track events, however many you attend, more cumbersome.

I agree that the other people who have posted previously claiming to have seen something similar to the Ferrari in your original post at local SCCA events "all the time" are flat wrong. I go to a lot of track events and I haven't seen anything like that...ever.

To me the notion of an enclosed roll cage is something that's just bling. The overwhelming point that i really wanted to make was that before spending the time to enclose your roll structure make sure it will be allowed by whatever track event sanctioning body where you might want to enjoy your creation.

I am at almost every SE NASA and SCCA event and have never seen an "enclosed" cage. There may be some in a BP car or some production series but even the top IT cars dont have any.

if you do plan on racing the car in any sanctioned events, just make sure you get your cage drilled, teched and stamped before covering everything up. you might even leave the area where it stamped clear so it can be seen easily.
