VIC: Good wheel alignment places in Melbourne

[Notso Swift]

No Dynamic alignment, which is done on car with a rotating wheel
Sounds like he has had the wheels balanced already with limited results

First I've heard of a Dynamic Alignment but technology changes all the time. I can't quite see the need if the wheels & hubs are running true.

I don't think it's alignment - it has to be really wrong to get a vibration.

I would go back to SS tyres and ask them to have another look. Firstly at the suspension joints (for wear and tightness) and subframe bolts. They should be giving the joints a push & pull as part of the pre-alignment check. I'm suspecting that either you have a loose subframe bolt or one of the console bushes (rear of the lower control arm) is worn. But it might be any of the bushes or pivot joints including the top mount of the strut.

Get the wheels off and get them to spin them on the balancer and check for tread wobble, sidewall bulges, flat spots & saw-toothing / scalloping of the tread.

Clean up the mating faces of the wheel & the hub.

Use a torque wrench to tighten the wheel bolts. Step1: tighten to 100Nm in a star pattern. Step 2: tighten to 120Nm in a star pattern.

I also think the factory recomended tyre pressure is a fraction high for most Australian driving conditions. I'd be aiming at 250-260kPa.

Beyond that the next step is an on-car dynamic balance (which I think is a bandaid solution to cover up other issues).

I have no idea what SS Tyres are like. I have a few mates down in Melbourne that race and they all use TruTrac but there must be more than 1 decent operator down there.

Centreline Suspension do Dynamic Alignments if you want to try that. They'll also check your suspension (all alignment places should do this before doing an alignment)
