Lane Change / Swerve Test - Tips

Good point on the welds - some of the factory welds on my chassis were bad enough that the engineer requested they be re-welded. lol

I Semi couldn't pass this test nor could most smaller trucks on the road at 100k's so what is the difference they are on the road.....

Which is why I suggested the rules might be different for commercials. A SWB soft top sierra is a passenger vehicle, a 2 seater hardtop (van) or a trayback is a commercial. Willing to bet the rules are different for commercials. They are here in Vic. (in some areas, not all)

Thats strange suzuki uses only the best asian welders it can find like this guy.

ahhahaah thats gold - and probably accurate at the same time!

My sierra is a 4seater softop but is considered a ute for rego in wa,
they still want it swerve tested.

The best welder I have ever seen is a korean guy. This dude can weld perfect with a stick welder whilst feeding in another stick with the other hand to get a big fat weld. In korea they do a 5 year appreticeship just for welding, not fitter/welder, not boiler maker/welder just welding. And the dudes at work who have "only" been welders for 10 or so years just do the grinding while the dudes with 30 plus experience are considered the good welders.

yeah but i bet they dont use newspaper and coke bottle glasses to achieve their welds =P

My zuk is also rego'd as a ute... it makes no difference in WA - it carries passengers.

Yeah, no worries. Commercials do have to comply with less ADR's though but obviously it's a different situation state to state.

I did the swerve test in my Patrol which was fairly lifted and in my SPOA zook with 32's and 4agze. I think your looking into it a bit to much. Does the engineer have a speed gun? Mine didnt. Just tell him you were doing 110kmph.

Besides that just hold on as it is bloody scary. Your zook will do it fine though. We do it on a drag strip here which is an 1/8 mile and i coulnt even get the patrol to 100kmph.

When you do the test stay as close to the cones as possible so you dont make the swerve any larger than it needs to be.

Thanks mate - in WA though we arent allowed to drive our own vehicles - its handed to a CAMS approved driver to test.... downside is he doesnt know the vehicle, up side is he's done hundreds of lane changes in lifted 4wd's... downside is he's rolled two so far... lol

I think it would be beneficial to allow the owner of the vehicle to do his own swerve test. I believe that owners know their own vehicles handling more intimately than a CAMS test driver!
It seems irrelevant to have another driver (CAMS approved) do the test as he won't be behind the wheel in a real life situation, when the manouver is required.
However so… If owners drove their own swerve test, they probably would have a lot more vehicles rolling or flipping during the test.

Good luck getting most sedans to 100kph with in 200m!

Are you sure it wasn't a 1/4 mile?

Post by **CanberraMav** » Thu Feb 14, 2008 10:19 am

Its definetly an 1/8 mile.

You can drive a bit past the finish line as well

Post by **alien** » Thu Feb 14, 2008 4:03 pm

ahhhaahh 200m my zuk would be doing about 80 i reckon... if i was realllllly pushing it i might make 90.

This is done at Wanneroo Raceway (Barbagallo) - the test is done on the main straight, so theres plenty of room behind that to start building speed. 110 wont be an issue.

Heh, when I did a defensive driving course with lane changes I needed a bigger runup than anyone else to get to 80km/h

Post by **mattc** » Thu Feb 14, 2008 8:04 pm

Like CanberraMav said, ACT has had a lane change test for ages though you get to drive yourself. I have no idea what the dimensions on the lane were but its done at 60/80/100km/h. I also was flat out getting to 100km/h in my wrangler as the old Canberra drag strip the engineer was using a few years ago was only clear from rubble in a short section.

Personally I don't think it is very bad at all (admittedly coil sprung, sway bars connected, ranchos turned up) - just swerve out and back in the ACT. It's not like you are doing 5 or more swerves in a row to get a big sway happening (like how they flipped that little Merc).

Edit : Sorry I forgot to say my suggestion is to go find somewhere and have a practice, build up the pace, and see how it handles. Apologies if this has been said before....long thread.

cheers

So what happened........... did it pass

Post by **alien** » Mon Mar 10, 2008 10:38 pm

its not done yet.... im still waiting to get a date confirmed =(

Post by **alien** » Fri Mar 21, 2008 7:24 pm

SUCCESS!

See a video here: http://www.youtube.com/watch?v=UCC2bTANUiQ

Just have to go over the pits now and the zuk is fully registered.

I made NO CHANGES to the zuk at all, other than running the tyres at 35psi.

Post by **MightyMouse** » Fri Mar 21, 2008 7:43 pm

Well done - you've put all us pessimists in our place

Post by **Drew** » Fri Mar 21, 2008 10:05 pm

good stuff ,the test doesn't look to bad

Post by **nicbeer** » Fri Mar 21, 2008 10:26 pm

nice one.

did they say anything?

also u running swaybars on that too?

Post by **alien** » Fri Mar 21, 2008 11:36 pm

doesnt look too bad on video, sure, but when you're there and someone else is driving your zuk at ridiculous speeds through a silly manouvre - its bad =)

Nic - nope, nothing said other than it handled well. and no swaybars.

Post by **OldGold** » Sat Mar 22, 2008 12:43 am

sure looks strange seeing a zook coming down the main straight at barbagello!

Post by **Lil'Loki** » Sat Mar 22, 2008 10:11 am

'92 WT
SPOA on lux fronts
vit 1.6 with 32/36 weber and 2" pipe
31" Coopers on 15x7" speedys
Calmini 5.14tcase

How do you think you'll go with the Weber over the pits?
I thought the DPI would pick on no anti-polution gear??
Just querying this 'cause I was thinking of doing the weber on my zook but the headaches of getting it passed worry me.

PS, Your Vid of the test ROCKS.

Post by **alien** » Sat Mar 22, 2008 10:42 am

dont know... the engine swap is on the paper work, and theres no law on changing the carby... i still have the cat on the exhaust - other than that theres no other anti pollution on the zuks from factory anyways =) if all else fails, ill plead ignorance...

Well done, Alien as you said watching it happen to your own 4by would have been scary (the lane change test) But watching the Video it looked like the Zook had no worries at all. Almost all this build up for nothing hey ahaha. Do you know if the driver got up to 110km...?

Good luck with the rest of your checks Im sure you will be fine.

Post by **alien** » Sat Mar 22, 2008 12:27 pm

well the first run he did 80km/hr through it, 2nd run we thought he'd do 90 or something but he just floored it instead, he said just over 100 on the speedo and a speed check by the engineer confirmed that - the issue is the bend before the straight - it doesnt let you build enough speed cos it such a big corner. It would have had no trouble at 110, especially seeing as i had no extra weight in there at all... not even a spare tyre in the back (hence you can see the back slides out a little).
