Fresh

Have got some BC adjustables installed in my GX71 and all is well apart from an issue I discovered the other day. When trying to do a burn out the rear end gets some pretty wild axle tramp. Now this doesnt really make alot of sence since its IRS but it feels like the wheels are bouncing up and down off the pavement. One thing that came to mind when installing the BCs in the rear was how to set the shock height. And I am wondering if the shock is set too short/long and may be putting a lot of preload or whatever on the rear and causing the tyres to bounce. GX71 has a separate shock and spring setup. The spring is height adjustable and this is what I have been adjusting to set the height of the car. The shock is also height adjustable but I have no idea what height it should be set at. Does anyone have any guidelines on what height the shock should be set at? I figure there must be a way of getting it relative to the height of the spring.

Anyone who wants to cruise down from Christchurch with us let me know so we can arrange a place and time to launch from. Leaving on Friday 24th at probably around 7pm. Have organised accommodation for the 4 of us so anyone else keen will need to book their own.

Ill give it a clean and a polish and get my mate to DSLR some pics.

Yeah man it was all pretty lame but has been worth it. Mine is about 50mm off the ground and has a shitload of camber, like 5-10 degrees. Even at 100mm it still had like 3 or 4 degrees. Mark II was allowed 0.3-0.75 degrees from memory so yours would be same. If you find a nice wheel alignment person they might be able to do some number tricks for you

Nice car man. Cert was a general bitch in every aspect. The new camber laws and tyre stretch laws make it hell. You cant have any camber in the rear so you will need to raise it up to about 120mm or somehow make the rear camber adjustable and wind all the camber out. Tyres will have to comply with the new chart. So pretty much have to run skinny rims with huge tyres to get them to fit in the guards. Had to get custom made adaptors for my wheel spacers and rims so they sit snug on the hubs. Front adjusties had to be crack tested after I got them welded but rear adjusties were sweet. Also having adjusties has been a god send otherwise I would have probably gone through about 10 sets of springs haha. As for the conversion I had a friend do all the work. Car was factory 1GGEU manual so made the conversion pretty simple. Merged 2x 1GGTEs into one with all the good stuff. Managed to get the winged front sump which sounds like a must as I have heard stories of people running bearings using the factory front sump from their 1Gs. All 1GGTEs come with a winged sump but most supras are middle or rear I think. Front only came on factory turbo GX sedans. FMI fitted real nice and snug with some pretty easy mods but had to rip out all the AC. Only thing that isn't working since conversion is the Tacho (I have Digi Dash). But pretty sure I have figured out how to sort that.

Car is now finally certed and fully road legal. Have put it back to how it looks above on the grass Andy has loaned me his BOV, need to put my boost tap on and wind up the boost and see how it runs. After my experience with Cert all I can say is good fucking luck. If I was to do it again I would probably get a Log Book and go down that path. All the new rules make it pretty much impossible to have a low car in any way.

I'm amazed that this is a 22 page thread and the turn out was about 10 people! About 8 of those people are people I see almost every week anyway haha.

That's mean. I'll have to have a yarn about it.

Is said coastguard boat the twin outboard one that roams Lytleton with the big air pontoon around it? Launches from the main boat ramp in Lyt?

Are we expecting decent turn out? I just got my car on the road and legal today so keen as for a mission.

Have you got cert?

Mmm arse paint.

is it not how they do it currently? Yeah it is how it is measured for Cert. Unsure what the "instant fail" means.

How do you mean instant fail?

Yeah more money and hassles. I guess it is an option. Probably just pull it up until the camber goes away.

As mentioned in the cert thread: Failed on tyre stretch (195/45/15 on 8s, and 175/50/15 on 7s). Too much rear camber. And car below scrub line (chassis is 50mm off the ground). Basically I have to raise the car up until I can get rid of the camber in order to pass as my car doesn't have any camber adjustment at all. Most probably have to bring it up to almost factory height. Retarded but there's nothing I can do about it. Pretty pissed off to be fair, the camber is all natural and doing exactly what Toyota intended it to do from factory yet in NZ it is now illegal. I guess I just enjoy the pictures of it at its current height and get used to it looking like a factory Mark II!

Subframe has been notched and exhaust sits nice and high now. Spacers are on the front and wheel fitment is good. May have to roll the front guards but will see what happens. Car is booked in for Cert tomorrow morning!

I am going in for cert tomorrow morning with Wayne in Christchurch so this will bring some things to light.

Seems pretty crazy. My camber is all natural but I assume that doesn't matter. Although it makes you wonder, if I was to get a wheel alignment with a full car load on factory suspension my camber would probably break still break the rules, yet it is working as Toyota intended it to when the car was made...

I am due to go in for cert any day and have about 2-3 degrees of Camber on the rear. I have only just learned about these new guidelines/regulations. After having a read here it seems that it really is more of a guideline than an actual rule. It mentions that: "In any case where a vehicle’s camber exceeds that recommended by the vehicle’s manufacturer, the LVV Certifier must ensure that the requirements contained in 2.2(2)(a), 2.3(, and 2.4(1) (referred to earlier in this LVVTA Information Sheet) of the LVVTA suspension standard have been met. The LVV Certifier must also take extra care in ensuring that the vehicle is safe and fit for purpose, based upon the following factors: -tyre width – the effects of added negative camber are more pronounced when wide, low-profile tyres are fitted; and - road and brake performance test results; and - the vehicle manufacturer’s wheel alignment specifications." This would make me think that if the camber isn't ridiculous and the certifier drives/tests the car and believes it to be safe then it can still be certed outside of the recommended +half degree rule. Thoughts on this?

Shit yeah, I'm already pining for nats again hahaha

So I have had the shocks cut and re-welded, allowing me to go about 40mm lower at the front and keep the springs captive. Going to get some spacers for the front this week. Last big mod left is sorting out my exhaust. It sits too low as it comes under the rear subframe, going to either cut a hole in the subframe on the opposite side and route the exhaust through that or get the factory notch extended so I can slip it up into that.

The last few posts made here about the BCs will make more sense if you look at the photos in my main thread. Have just had my thread split up and put where it should be thanks to KK.
