Yes, 2010 takes a different front pad than prior 997 GT3 and rears were totally different startign with all 997 GT3 - 1 piece caliper, remove to replace pads. Surprisingly easy to do, actually. Just have spare bolts on hand BEFORE you do the job -

OK. I think I've solved the mystery of the seemingly unmatched brake pads, i.e. Pagid P90FF fronts and Textar rears on my late July delivery 2010 GT3. TRAKCAR helped too. After talking to Craig at the Rennstore he opened my eyes on mismatched pads on the GT3, recommending not to do it. I thought I had screwed up, but after further review I am actually in better shape than stock, even though I am still stock. .......Huh??

Here is the deal. The dealership gave me a print out of the technical info on 10 GT3 brakes. Standard brakes are listed as either part #'s 997.352.941 or (942) .95. The 942's that I purchased are in fact the Pagid P90 FF pads. I now have a matched P90 FF set of PAGID f/r pads. Also listed on the tech bulletin is the 997.352.949.01 Textar pad, with the statement that "In addition to the current standard pad specified these pads were installed on the rear axle in model year 2010.

So I think what happened may have been a sourcing problem in the earlier build cars and that later cars probably have a matched set of P90 FF Pagids. It also looks like the GT3 and GT3 RS have the same stock P90FF brake pads as noted by TRAKCAR.

Sorry for the long post but this was driving me crazy. I feel confident now that I have a matched set of the more performance oriented pads as the Textars rears were rated as a "comfort" pad. I would also wager that many of the later build 2010 cars and 2011 cars have the matched Pagids. I guess there is "stock" and then there's "stock".

I had the same on my GT3, I carbonized the rear disks That was an expensive operation (new disks) after only 1.5 months of ownership

KBS911

Ouch. Did you carbonize the rotors or the pads? Hope it was just the pads. I noticed the black/carbon effect on my pads. Rotors are fine.

It appears that with electronics on, the HIGH rear factory bias + fairly weak OEM pads equals tremendous rear pad/rotor/caliper heating. Well, not 'appears' - fact.

I am seeing DOUBLE the wear rate on back vs. front !!!

Carrera GT

To clean the rotor surface, or de-glaze the pad surface, use a non-aluminum-oxide abrasive like the 3M brake rotor discs ("Garnet" paper.) A machine shop might have the equipment to "Blanchard" grind a disc that's still in very good condition but has pad material deposits that cannot be removed with Garnet paper. Note that this is not "resurfacing" the rotor (which would involve precision machining of the rotor to remove surface irregularities ... this is something that generally is just is not done today ... it's a matter of liability and safety as well as cost compared to a new rotor.) Also, if you want to learn about brakes, this information from Stop Tech is the most complete and accurate that I've found in the last decade or so.

FWIW, I think that is mostly TC and SC..

In the MKI GT3 with everything off, I had equal wear front to rear.
With everything off, it appears to be the same on the MKII, but I only have 4 days on the pads, I just flipped the fronts and will report in after the next 3-4 track days (The weekend after Aug 8th.)

Carrera GT

The RS seems to have balanced out the front-rear wear. Perhaps it's more front grip or better rear cooling. The leading edge wear on the front pads brings on that "wedge" wear profile, but I wouldn't go below about 50% usage (when wear starts to accelerate ... bad pun ...)

Does anyone happen to know the stock thickness of the pad material on the stock pads and the Greens? Are the PCCB Greens different?

Rotors :/

First we thought it were the fronts, so we replaced those, alas, problem was on the rears. 4 new rotors. $$$

ir_fuel

Wow.

I drive with TC/ESP on all the time, do mainly Nordschleife with the car and had equal wear back/front on the brake pads. Maybe your esp does overtime?

TRAKCAR

After 8-10 days they were 35-50%. I will report back if it is still the same.

The OEM ones are 15mm ncluding thebacking plate (5mm)
FWIW, I just measured including the backing plate the Pagid R29 are 19mm. I throw them out at between 10-14mm including backing plate (5 mm)

Carrera GT,
Good info and a great link. I will bed my brakes in this weekend.

To all: Great info and feedback. Thanks, I've learned a lot.

Since stopping is as important as going, good brakes and brake maintenance are paramount. Interesting to learn about the more subtle characteristics and nuances of the GT3 brakes.

Victory favors the prepared!

I know this is an old thread but I am coming up on having to do rear pads and I wonder how I will be able to get the caliper off with the rotor worn down and having an outer lip. Pads will not be able to clear that unless I somehow manage to push in the pistons..

Any ideas?

Thanks.

Regards,
CF

I use this:
Girodisc makes a nicer one. The above works fine for me. you may need to keep pads on as you spread them vs. pushing on just pistons once the caliper is off.
