good point, my garage obtained the spec from a maserati dealer who emailed it to him so i never actually got to see it, all i knew was that it had to be fully fuelled and 2 x 80 kgs ballasts in the front seats (2 spare mechanics)

QP and GT are the same settings on SupaTrack I assume this is the same accross the board.

I need to state that I am not sure if the specs I posted are for the early Duo-Select and the later Automatic cars.....or......are they the same?

Not sure why prices have risen so dramatically since I'd last had a four wheel track done on Hunter-equipped jig -- last was three years ago for a Jaguar XJ8 '01MY 3.2L.
Last week one shop tried to charge me £430! "It's special and difficult for a Maserati, sir!" :cent:
This shop (in the same area of Essex -- London commuter area) charged £192 and has yet to apply increased shims to the OSR to bring that back into tolerance. My local italia car specialist quoted me £200

This post follows for an '08MY QP M139 shod with new PZeroes 19" at 32psi all round (should be 32 front and 29 rear). I don't know whether there was two sitting in the front seats or not. Or their weights ;-))

But yes, what a difference! Drove back from dealer that I'd purchased from (one previous owner from new) and could feel on the motorway it was not as stable as it should've been -- tramlining and steering too sensitive to change -- symptoms of tracking out. Mind you, tyre pressures too were all over the place to try and compensate for a loose NSF low beam headlight fitting <groan!> e.g. OSR 49 and NSF 17 psi

I recently noticed extreme wear on the inside 25% of my rear tires. I took some primitive measurements and observed that the Camber was at -2.1 degrees, and the toe-out was at 4 degrees - which is what the information I have says the tow-out should be. So it's obvious that these settings would wear out the inside edge of the rear tires. Personally I could not justify buying new tires since the current ones have lots of tread on 75% of the contact patch. You may think I'm crazy, but I took matters into my own hands and made some adjustments. I cranked the camber back to about -1.0 degrees, and this resulted in the previous toe-out going to a toe-in at about 0.6 degrees. I've noticed a very slight reduction of steering response, and very slight "step out" at the rear when going over certain bumps, but the car still drives very well overall. This weekend I plan on adjusting the toe-in to around 0 degrees which should eliminate the "step out".

A while back I took some flack (on the other forum) for even suggesting any deviations from the factory alignment specs. Feedback regarding rear tire wear was very inconsistent, some reported even rear tire wear while others reported very rapid rear tire wear. Since my QP is a daily driver, I am going to set it up for that as best I can. Okay....let the flaming begin....

You haven't said what car you've got and its year, and mileage, and wheel size, and tyres you've got on it, and what pressures, and the price of fish where you are... :p

I think mine is set to 0. To stop inner wear

We at SportsItalia.co.uk charge £140 all in, including shims.

We also run a modified front camber/toe setting to stop the inner front tyre edge wear setup for UK roads.

i had my gt done today, inner wear was an issue. It is now set to 0.5 toe in. I used a shop specialized in suspension and they do a manual alignment, costs a bit more but they actually know what they are doing and dont need a factory sheet of specs to setup a car how you want it. They suggested a lower toe in on the rear as well, so the back follows the front a bit better.

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.

Who would you recommend in/near London? (I live in SW1). A few places with Hunter machines all said its to hard, and to take it to the dealer (HR Owen).

I also have the inner 25% excessive wear, but on the rears only as far as I can tell...

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
