Hey all, I've been hanging around here from a while now, reading all the tips and tricks and have learned heaps. I thought it was about time I introduced myself and my baby.
Shes a 91 V8 UZZ30, no mods except the 18" mags.
I want to get the intake and exhaust done up, except first of all I have to fix a slight problem with a speed wobble at 100-120 which i think is being caused by something suspension wise.
Beaut car though, my first car in fact  Love it. |

Cheers guys.
Hey Joe, I'm from Marlborough myself, just moved to Christchurch this year, I still end up in blenheim about once a month. (You can probably see the bottom pics are taken at whites bay ). Got some pics of your car? Don't think I've seen any other soarers up there. |

UZZ30's are good fun! The wobble is probably wheel related, either out of balance or tyres out of round. Try swapping the wheels front to rear and see if it changes.
It's still worth getting the suspension checked though, most likely the bushes will be shot unless they have already been replaced. |

The wobble doesn't come through the steering wheel.
I have put new tyres on all round, had a wheel alignment done, and took my rims in for straightening but all four were found to be straight. So the suspension is the next thing to look at.
The wobble started when my mate was driving one day and managed to spin it out on a 90 degree corner, ending up sliding at about 80kph exactly perpendicular to the road. |

Flat spot on the tyres? |

Nope, it only happens at 100kph, and then goes away at about 120kph. New tyres all round anyway so it couldn't be a flat spot. |

They aren't new tyres any more!
But wobbles coming and going are often balance related. |

Yeah I've heard that it can be balance related. The front left rim has about 20 balance weights around the outer rim, as opposed to about 6 to nil on the other rims. This is why I thought the front left rim was bent (as i got the front tyres new a week after the spin).
Should I take it to be rebalanced? Because I thought it was a computer system... highly accurate |

A weight might have fallen off. One time when I had my wheels done, next morning I see a shiny new weight lying almost next to one of the wheels. It must have dropped off just as I was pulling up.
Took it back to the wheel shop, and one wheel was out, so they rebalanced it for free.
20 weights though, is a lot. Suggests a problem with the wheel or the tyre to me. |

I would guess that the problem is your aftermarket rims aren't hubcentric, and they are moving around on the hub. Probably your mates little incident has caused the studs to stretch a bit and thats whats made it more noticiable since then. Get some rings to suit and all will probably be well. |

I agree, 20 weights is a lot. When I took it into a rim straightening place, they checked all four rims and found them to be straight. I asked the chap why does the front left have 20 weights on it, and he said some tyre/rim combinations just do that sometimes.
But the other thing he also said is exactly what you said there Matt. The rims aren't hubcentric. By rings I presume you mean spacers right? Just to make sure we are talking about the same thing |

Not quite. These are what you want to solve your hubcentricity problem:

Cool thanks mate, I think I'll go into the rim specialist place tomorrow and get some made up for it... if they don't already have some. |

Unfortunately in NZ the rings aren't required by law, which is just nuts - I'd say about 90% of cars with aftermarket rims in NZ are not mounted to the hub properly. |

I'd agree with that, and its bloody dangerous- a friend of mines GT-4 was ripped to shreads by his wheels no having those (spigot?) rings. Well worth the $15-20 you'll pay. Get your studs checked to, some will be bent or pulled. Thomas, I'll take some pics of my Soarer this weekend and get them up in the introdruce area for all to look at  |

Very scary indeed.
When putting wheels on the spigot ring fitment is the first thing I usually think off.
It seems totally illogical having all the weight on the studs...
It simply comes down to people owning cars that have a lack of knowledge about changing parts around, so they end up making it less safe - however at least it looks "cooler" (Yeah right 95% of the time!)

I saw a late 90's BMW 5 series at the supermarket yesterday on 22" chrome rims! It looked like a roller skate. |

Haha!
It's just sad what happens to some nice cars, and how much money is wasted.

Got the rings fitted today and went for a drive... no luck, still shaking/wobbiling/jittering.
Really frustrating. I think the next thing I'll try is getting the wheels rebalanced, and then checking if the studs are bent. Where abouts would you go to have the studs checked? |

As long as the rings are holding the wheels to the hub centres, the studs shouldn't make much difference. First get your suspension checked - bushes, control arms etc - if all that checks out, I think a wheel balance and alignment is the way to go - that should pick up if any of your rims are warped, which could also be the issue.
Hey, at least you have fixed a definite safety issue on your car, so thats one thing to check off the list. |

Hmmm.... Thats odd Thomas. I'd say you'd notice if the studs we're bent as soon as you pull the wheel off, so Mattthew has the right idea. When are you next up in blenheim? I'm away this weekend but might go for a road trip to chch soon, would be good to see your ride  and maybe have a beer! |

Sweet as man, would be keen. I may be up this next weekend coming, i might flick you a pm before then.
Still haven't done anything about the jittering yet tho... haven't really been driving her much except to and from work so it hasn't really bothered me. Hopefully fixed before christmas |

Update:
I did finally get the jittering fixed, turned out the balance weights had fallen off the rear left mag... probably when my mate spun it out . Oh well she drives as smooth as silk now, and it was free to get it rebalanced.
Taking her in today to look at getting her lowered about an inch or so, kind of wish i had a '31 |

Haha, the UZZ30 is the desirable one Thomas!
Lowering an airbag just stuffs up the ride and shock performance.
I found that when trying it out before swapping the air struts for coils. |

I did then, but now a few months on I think rather differently.
Yours is best at the current height, due to your drive way problem.
