Hey guys due to getting ban from the track I am in need of a rollcage. This is new to me and unsure what to do. Good shops to go to, cost, certs etc

Going by your previous posts, you're Auckland based right?

Do you need a full cage or just the roll bar half cage?

if it’s a half cage you can just cert it via LVVTA. 

 

Full cage requires licence and money

Not sure what I require. If this helps the cars fully road legal an I use it couple times a week weather its cruise or short drives. I use for odd drags and track days like chrome flat nats etc etc

Ray Chubb. He's built plenty of roll cages and does them to a very high standard.

WIf you need a full cage then you need a Motorsport authority card which makes it road legal and no LVVTA cert required. 

 

Ive has both in cars and were done by road rally race, Ralliart. I was lucky and got one done by a guy over here from Ozzie Supercars looking for extra work. 

 

Cromolly cost more and can’t be repaired if you bend it. 

 

also the handling changes with a full cage and the chassis flex vanishes.

You would need a 6 point at minimum but in your case to keep the car road legal you require a 8 point which goes to the front strut towers. You just go get your MSNZ licence then apply for a authority card no cert required.

What Inked said is the best practice. 

 

If you've seen the likes of @RaKid's engine bay, and you want quality work (Not saying the others suggested aren't at all) then BD Motorsport is a place I'd recommend. A close friend of mine who used to work for them, and is now working for Cameron Racing in the states for GT stuff, says their work is top notch and Ben is really good at his stuff.

If you go forward through the firewall find someone who’s done the Subaru before. Ie go ask the rally guys. The last place I when had templates for all the cuts in the body so it looked great. 

Rally places may already have something they have planned and ready to bend up fast.

There is also a place in CHCH called NZ rollcages and they pre bend kits for you, example a half cage kit shipped to wellington is $290.00 incl.

 

Could be good to look at then you just need to find someone who can weld it up

Can NZDRA cages be used at MSNZ events?

 

I know that some years ago the answer was a resounding no - you could go run a 10 second pass with a super ropey half-cage made of exhaust off-cuts arc-welded together in your mates garage and that was more or less fine, but MSNZ would laugh at you if you tried to get the cage homologated.

From a quick look while I was at a conference today. That nzdra book says  you can use it for both provided it is cromolly. And meets both standards.

 

Also has something like sub 9.90 is full cage,  11.00 is half based on a what the chassis is. 

 

Msnz cage youll have to do two club level events a year to keep it legal.

 

Youll need to read both books and talk to a couple of shops that do drag and rally as forum world isn’t gospel

I'm slightly interested in these circumstances, more info?

 

Even Playdays have the prestige 'class' which can be as 'dollar efficient' as committing to a cage

If you run sub-11.0 you aren't allowed to run again until you have a cage (half-cage?).

If you're not worried about getting it homologated for circuit racing and only want to do drags, you only need a 5 point half-cage. Good for up to 10.00 sec.

Seeing you're Auckland based (Meremere), NZDRA does not apply as they adhere to IHRA rules. Go to section 3.61 and you can see the diagram they provide.

You will also need an SFI approved crank pulley, fixed back seat, harness bar and harnesses, shield plate over top of the transmission in case of flywheel exploding, drip tray underneath engine, etc. List goes on. 

Worth talking to an IHRA tech inspector before you start.

Going for 9s you need a 6-point.

We're on the road to 9s as well, although as the car is still mainly street-based I decided that we're going to do a 5-point half cage to keep minimal bars in the car. If we get kicked out then I'll still be happy that we've run a 9.
