The thing about that, is you're talking about an 8.50 drag racing legal cage with the use for back seat, if you want the rigidity for road racing, and the ability to pass SCCA/IRDC inspections, you'll need a little bit more in the cross bracing departments, along with a bunch of gusseting.

 

drag racing standards are very low in comparison to road racing. you just want stiffness, it doesn't sound like a cage is right for you

 

Caging is what most people do to stiffen the chassis in race cars, the added safety it provides is just a bonus.

So a cage is exactly what he is looking for, added suspension helps body roll, but the true stiffness comes from the bracing and caging, the rigidity is incomparable when a cage is added.

 

i would think the complete opposite. thinking like that is why kids buy roll cages on street cars and then wonder why they had massive head trauma from an accident.

 

Bingo!

If you are looking for a drag race cage to make your self legal for a sanctioning body get your self a bolt in cage. It will add some stiffness but you will also be able to take it out if you safely want to have people in your back seats. HAVING PEOPLE IN THE BACK OF A CAGED CAR IS 100% NOT SAFE


If you are looking to build a road race cage, there are quite a few shops in the northwest who do great work and i would be happy to share some of that info with you if you want.

If you are just trying to add stiffness to the car strut bars and seam welding are great ways to go that wont effect the use of your car as a daily driver.

 

Bradze, I have a back-half roll bar, and it greatly affected the rigidity of my chassis, and it goes no where near my head, if I was to get in a roll over accident, I would not even come close to it, and I bought mine for rigidity, because I don't need safety on the street or daily driving, it just makes the experience way more fun.

 

Well I'm far from a "kid" and no one rides in my back seat. I want to keep the back seats because I like the way it looks with the seats still in place. I do want to pass the standards for SCCA because I don’t drag race much. If I have to take the seats out for this then I will. My car is a weekend driver and general weekend "toy" so wrecking it on the highways isn't likely but it's always a possibility as I can't control other drivers. My car sees the Highways on the weekends for cruses and meets (although I don’t make it to many) and I'm going to be driving it to races in Kent but I'm not crazy on the roads when I'm in it. I'm actually pretty conservative when it comes to my highway driving (in comparison to the soccer moms in their mini vans with the "baby on board" stickers).

 

Then don't let anyone sway what you want to do, it's your car, do what makes you happy, If you're going to do a full cage, it is smart to only drive the car to and from the track without a helmet, because as Bradze stated, the a-pillar's and roof bars are EXTREMELY dangerous.

 

If a welded in cage is the only route you are willing to do, I would give up hope on a back. Just build a rear bulkhead/firewall like the one in the thread you linked..

I would call a shop and talk to them about your options. They will have more experience than any of us here... Here are a few...

Hopefully this will help you out.

 

Thanks guys!

 

So, what would you guys suggest for DD and road racing? Bolt in?
