Granturismo whhel alignment- A warning!

My car has been off the road for 10 days following a botched alignment/geometry- caused by a national tyre company that does many Maseratis in my area and should know better.

I have since become something of an unwilling "expert" on Maserati wheel alignment : In the hope that it doesn't happen to anyone else I'll relate the story;

It started simply with a front tyre badly worn on the inside edge (very common apparantly on GT's)
I had two new tyres fitted and naturally asked for wheel alignment to be carred out at SETyres, who have the right equipment to do Maseratis (Hunter) and do many geometry checks for a local Maserati specialist.
They should have known what they were doing.

There is lots to go out of adjustment on the Granturismo and I can see why yearly alignment checks are recommended by Maserati.
The job can easily take 3 or 4 hours to do properly.
One adjustment (think its toe-in?) is on the lower track control bush, which is fluid filled. Adjustment is by the way of inserting Maserati special shims, and by a variable thickness sort of washer on the bolt that runs through the rubber bush which sits in an aluminium housing.

The problem is that as these cars age the bolts seize up. In my case the technician at SE Tyres was turning the bolt to adjust but in fact was twisting the bush. These bushes are OIL filled- result was two ruptured bushes-oil leaked out- result 2x new bush sets required (three each side, £250 a side + labour 10 hrs)

They admitted liability and the car went to my local Maserati specialist in Kent to do the job. All 6 track control bushes have to be changed (bushes come as a set)
This is a ten hour job. Special tools are needed to press the bushes into the arms.
Retail cost is nearly £2k. Every single bolt was seiized and had to be cut off. This took hours/days to do.
While it was apart the drop links and strut bushes had signs of wear (my car has only 19,000 miles) so I agreed to do this to whilst it was apart.
Finally the car has to have another 4 wheel geometry check of course.

Phew- So anyone having alignment being done it must be done by someone who has not only the correct equipment and knowledge of our cars but also knows that the bottom track control arm bushes must not be twisted or...£££££££mega!

SEtyres bill £2000 My bill £1000 (one front spring was also broken- apparantly also not unheard of) Oh well at least I have a completely overhauled front suspension now should be good for another 20,000 miles......

What is it with Maserati and suspension parts...this and worn wishbones costing mega bucks...are they made from glass...your car has done just 19k and the suspension is rusted solid!

Good grief. I had my alignment done (3200gt) by SEtyres and they did a great job and you're right they do work on loads of Maseratis so should know better.

You don't live down Greenway, in Tunbridge Wells do you? I've heard of a GT that lives down there.

20,000 miles is about it for the suspension parts. The ball joints on the 3200 last about that, unless you nurse maid them. its really is a bit dire. Geometry is a nightmare, even with people who know what they are doing, I have had my car put to factory specs 4 times in 7 years and needed to adjust it after each setting to get it to handle right. Got some slightly different settings off this forum and these improved it a bit. Sounds like they have not made it any tougher on the new cars, if anything worse.

SEtyres are incompetent and shouldn't be let near a wheelchair, let alone a car! I have had a very bad and dangerous experience of this that I will not share publicly, but will happily discuss via PM.

That is very disappointing and highlights the fragility of the cars.

FWIW they do seem to wear the inside fronts badly on the P Zeros. They are fine on Sotto Zeros (winter tyres) so I feel part of the issue is with the tyres. I wonder what will happen with the Michelin Super Sports?

I don't know if the components and set-up are the same as the QP but my QP's front tyres were destroyed on their inner edges. McGraths told me it was down to the factory setting having too much toe-out. This makes the car DART into corners but eats the tyres.

McGraths adjusted the toe to neutral, and did all the other geometry, for me for half an hour's work: £30.

Wear across the tyres is even now and I prefer the car's handling.

Interesting - I like the darty feeling on turn-in. Not sure I am such a fan of premature tyre wear!

I loved it too but the flip-side of that was I found the car was very nervous at the front end, too easily upset by lumps and bumps, of which there are many on our roads. In the first week I owned the car I remember the steering kicking like mad as I went over the dashed white line during an overtake, my brother sitting beside me commented that if he didn't know we were in a RWD car he would have sworn I was fighting torque-steer.

Setting the toe to neutral has cured all that. It doesn't quite "jump" into corners like it did but you would be hard pressed to criticise the way it does take corners. For me it's a much better compromise; easier to live with and not destroying tyres.

As above I'd avoid anywhere that hasn't got direct regular experience of these cars. I had mine done on a Hunter machine to apparently factory spec twice ( after a pothole tyre blowout), and the results were appalling. Took it to Colchester Maserati and let them do it how they recommend, rather than the factory, and it was transformed.
