It is disappointing that so many shops will not do the alignment job on a Maserati. I know that those fancy alignment machines look intimidating, but the fact is that we are really only messing with 3 parameters, Camber, Toe, and Caster. I sometimes think they want us to believe this is some mystical rocket science. If you have 20 inch wheels on your car, and you measure at the outer "Lip" of the wheel, for every 0.250 inch you move the toe or camber....that equates to 0.68 degrees. So if your rear wheels tilt inwards at the top a half inch, then you have a negative camber of 1.36 degrees.

When doing this work yourself, you need to make sure that the last movement of the car is in the forward direction, before making any adjustments, so all of the suspension is biased as in normal driving. After each adjustment I did, I drove the car around the neighborhood and then confirmed the measurements. Right now my rear camber is at -0.6 degrees, and the toe at "0". So this should result in more even tire wear.

I tried HR Owen who, after they'd glared down their nose at me no doubt checking whether I was wearing the right old school tie, announed that they would only "deem" to take mine in after a full diagnostic scan costing £127 plus VAT! What a bunch of snobs :rolleyes: My Hunter effort is as above in thread. Does run much better now than before, even though its rear end isn't complete. What a faff around for such a prestige production car!

There's also SuperCar Italia next to Biggin Hill airport who quoted me £200 +VAT. I don't know whether they stock the shims or not. Yes, others claiming to be Italian supercar specialists just sighed into the middle distance when I asked... :confused:

Chichester or Soton's a bit of a run out for me. Luckily was at Southampton as a student (in the 60s ;-) so wouldn't lose a day.

CatmanV2's recommendation Wheels in Motion are Chesham. They seem to have other names -- Blackboots and Chesham Tyres. There's also an address listed in Tonbridge. But dunno if that's uptodate
I thought going to the dealer for a wheel alignment was a joke.... but apparently not! As a first step I will get a quote from HR Owen; to be fair they have not been bad to me parts wise- have gotten a trade price on my Lambo parts, and the recent wheel bearing for the QPV. I've just never used them for actual labour/service.

Bwa... hahahhhhaaaaahhhhaaaa :p

The real concern is that there must be numbnuts around prepared to pay this!

Of course the H R Owen of today is not to be confused with the H R Owen of yesteryear that was owned by that criminal of the Guinness scandal Gerald Ronson. Oh no...

Thank you for your business. You were served today by Robin B'astard :as002:

Just means they don't really want the business. They'll need to have one of their people take it to WIM, wait for it and bring it back. All labour charges....

I finally got around to adjusting the rear toe alignment. As I stated previously I recently adjusted the camber, which resulted in a bit of toe-in. In dry conditions I did not have any issues, but yesterday we had rain and as I was driving on the highway the rear end was fish-tailing slightly depending on which tire had the most grip - it was very alarming - not safe. So as soon as I got home, I adjusted the toe to be "0". I was not able to rotate the rod-link for some reason, so I had to actually disconnect the inner rod end from the frame of the car and adjust the inner eye, and reconnect everything. It was a pain but the job is done.
Thanks for the update. I've got the QP5 '08MY with 19" rims -- think over there you refer to it as "Automatica"? Am planning on going to Lancaster Maserati today to see whether I can get anymore service history as I've only got service stamps in the service book but no invoices.

Having rear Toe at 0º seems to have been a common setting instead of between 0.17º - 0.21º recommended on the Hunter specs

When at the main dealer today will ask about shims -- whether they come as a set or how they're supplied? My Hunter set-up shop said they had no more thread to pull the OSR in anymore into what the Hunter database said it should be
