My ultimate goal is 1m50s flat on street tyres.

More seat time, maybe soften the front anti roll bar to reduce the car washing out on high speed corners and maybe brake a touch later.

Only my 2nd time on SMSP as well, much more practise is needed.

A few more photos of the shit box.

And lap of the shit box, conveniently no GPS data on the VIRB for half the night. But you can see the speedo go past 180km/h lolol

 

[niZmO_Man]

At least your car can go past 180, mine was sitting on the speed limiter down the main straight hahaha.

Power delivery looks smooth, just needs more limiter while bouncing off the ripple strips

Some data from the main straight

Trying to find a cage with works with the entire interior with a removable cross bar and removable harness bar. Seems no such thing exists.

AGI might entertain the idea of both parts being removable but they aren't keen.

So for now, I will be installing a harness bar so I can use a harness with my fixed bucket seat instead of a normal seatbelt. Here's hoping it provides a bit more safety compared to a conventional seatbelt if I ever bin the car at the track.

Time to find a proper race car with a proper cage maybe.........

Proper harness is good and can wear a HANS device too.
They wouldn't want to build something with removable bars as won't pass MSA regs. 

[The Bogan]

Fixed seat with a harness and only a harness bar is great, as long as you don't roll and crush your spine.

 

Bond roll cages Australia built/installed the 1/2 cage in my old 33 with a removable harness bar. Fine if you don't need to comply with some regs

Yeah that's probably why they're hesitant, however I'm not going to be professionally racing the car. The cage & harness is purely for a bit more safety over the OEM gear.

Will get in touch with them in the future, see if I can get something that works for added safety with the option of keeping the car street friendly when not at the track. And you're correct, I don't need to comply with regs as I'm just a casual track racer and not competing 

[The Bogan]

Found an old pic, you did need to "negotiate" the cross bar though, I push alot of the old 33 out of my brain for sanity reasons , rear seat still fitted without the harness bar

Yeah I understand that, I have had a low speed front corner impact at 70kph into a concrete barrier once. It hurt with bruising and proper concussion for a week, No cage, 3 point seat belt and helmet. The big one in the getz at over 100kph, fine no problems small bruise from HANS on my chest. State level 6 pt cage, winged seat, HANS, 6 Point harness.

These are the current regs for cages. Anyone that does cages will reference this.

I suspect a few things will change in regard to bolt in cages and joints. Have a good read of this and you can see why there will be changes.

Imagine coming unstuck turn 1 at Eastren Creek and hitting kitty litter sideways then rolling at 150+kph.

Can't put a price on your life.
I've done some high risk shit and look back going WTF was I thinking doing that even with silly amount of training. It was f**king exciting as shit when it went right.

Does the back seat ever get used?

Read half of the report so far, very informative.

Scary the roll cage failed and literally bent like a stick of butter. Also what's shit house was the barriers weren't even concreted in properly, was a clusterfk of things.

Yeah the joints weren't up for it especially when you read the tech stuff.

Barriers weren't there really to stop cars. The data from the car is interesting to see and how the can interpret it. 

The new stuff that is coming for cage rules will affect everyone. Need to be 50mm from memory from occupant to bar. Especially the smaller cars.

@robbo_rb180

pretty much if this was individually bolted down OR welded down the driver would have been fine

Man, after reading parts of that, I want a cage now.

[robbo_rb180]

That report will hopefully open a lot of peoples eyes to safety and what can happen at lower speeds.

This is why I have that s15 to put a driveline in. I want to be safe and even in the 180sx with half cage, seat and 6 point harness I still feel its sketchy at Lakeside.

Have a proper chat with AGI or another fabricator. There will be a way to have a decent cage and make it tight to the interior.

rarely these days, it usually just has jerry cans LOL

But at some point I will put in a baby seat, just when we need a 2nd car (rarely).

[Jasoncauser]

i wasnt allowed to buy a track car unless it had a cage (wifes rules) so I have a 6 point bond bolt in cage.

I have heard some horror stories of cages ripping right through the floor when (particularly older jap cars) landing on the roof dead flat in a rollover
