FWIW, Formula Dynamics does heavily specialize in Maserati and we've offered these Sport Rotors for the QP since 2010 with excellent reviews on this forum and elsewhere. The price is very competitive as well. Pretty sure that we have more experience with stock and performance Maserati parts than anyone else in the market today. Of course, we do also offer factory parts for those that prefer OEM at a great price.

We have pads to match and can put together a package for you that suits. In any case, just let us know if we can be of any help.

Best Regards,

The last service I had the dealer said the discs were close to the wear limit so I had new ones fitted requesting to keep the old ones.
On inspection of the old ones there is no noticeable lip in between the worn surface and the un-worn surface. car has done 28,00 miles
Does anyone know what the difference is between new thickness and wear limit thickness is?

Best case scenario is I have a pair of front discs spare :-)

The spec is written on the outside of the rotor and varies based on model. However Maserati rotors will wear 2mm overall in most cases before they have reached the min. limit. So a 32mm wide rotor (overall), will be fully worn when measured at 30mm, which needs to be measured at the lowest point or deepest grove if the rotor isn't completely flat. This is usually tough with most calipers as they will get hung up on the wider outer / inner lips so extra care or a special tool is often needed to get this measurement.

The quick answer is that if you're at 28k miles, original rotors and you have good lips on the inner / outer edge of the rotor... it was time to change the rotors. We see that most fronts last around 32k miles. Some will do better or worse depending on highway miles, how hard they run the brakes, etc...

Hope that helps!

Respectfully, I'm just going to reflect back to you the things you said in your posts:

1) You asked about aftermarket rotors and pads for an unknown European manufacturer (I happen to know they are not Maserati OEM).
2) You raised the liability issue regarding non-OEM parts.
3) You wrote of Brembo products, which are also not OEM.

If (2) trumps (1) & (3) for you, your decision is made.

In the hypothetical situation you described, any potential claimed liability would fall to others besides Maserati. If you pressed litigation, discovery would reveal the manufacturer (If you didn't already know it), where your case could be directed.

Does that help with your decision-making, or have you already made it?

Again respectfully,
KTBD

Is it a similar story for the rear rotors as well as the fronts?

I cannot think of one auto manufacture that makes brake rotors or pads...They simply buy them from a vendor and put them their box..There is nothing wrong with aftermarket brake rotors...Like it or not almost all these components are made in China...If you want OEM than keep the box as that is what you are paying for.....Jason

Eurospare has been giving promotion on Pads and Rotors for quite sometime:
Maserati QTP. (2006) 4.2 - Rear Wheels Braking Parts: Page 411 | Order Online Eurospares


However, im so dissappointed that 07 QP Automatic will not fit with this drilled rotors.
Eurospare also told me they have customer bought this Sport Pkg rotor and tried to install on an 07 QP Executive GT Auto, and it doesn't fit.


No idea why 07 QP Auto is missing on the fittment list...:-(

Sure would be nice to have a rotor source as I'm about to have to replace all four and pads at the same time. Can anyone confirm the difference between pad options for the 07's? I have 07 auto exec gt. Not sure if the rears would be 4piston or 2 or how to tell without first taking apart the brakes to confirm.

It's easy to tell.

I had the same query. My car is 2008 model. Based on Formula Dynamics's site all 2007+ cars have 4 piston rear.

Take a look of my rear caliper and a 2 pistons caliper.

You can EASILY tell the difference from Eurospares spare parts catalogs 2006 model vs 2008

I know this is a pretty old thread but wanted to thank everyone who posted info here as it helped a lot finding decent (and reasonably priced) pads for my 08 QP Sport.

Since mine had the four piston rear calipers the Auto Zone DG1053 (ceramic) pads fit like a glove except they didn't have the notches in them for the break wear sensor so I just zip tied the sensor to the wiring harness and everything works great. Noticed a considerable improvement in stopping power over the worn out Brembo pads that were on it.

Had to special order the MKD639 front semi metallic pads (no ceramic option at Auto Zone) so that's a project for next weekend.

Thanks again!

Got the fronts finished today, the MKD639 pads worked perfect. They were a little tight on the ends so had to sand the sides for a few minutes to get them to slide in nice and smooth. Like the rear, the pad wear indicator didn't fit so tie wrapped that out of the way.

Overall, very satisfied with the performance of the pads and less than $120 for everything front and rear guaranteed for life and that's a big bonus since the last OEM sets only lasted 20K miles...

Made a minor mistake in my last post the rear pads DG1053 are actually semi-metallic not ceramic as I first thought.

Thanks again to those who did the research, deeply appreciated!

So after zip tying the sensor did that cause an issue with the Brake reading it as a fault?

Thanks!

You are welcome, it is a pleasure to help keep these expensive cars maintained as affordably as possible.

There are two contacts in the sensor that, when worn into by touching the rotor, make contact with each other to illuminate the brake warning light. If the sensor is tied back and was never worn into heavily, then it'll be fine. But if your brake warning light is already lit, then you may need to replace the sensor (hooked up or not), or somehow separate the contacts to shut the light off.
