Stoptech Sport Trophy Big Brake Kit
Have any of you guys used this brake kit before?
I was considering swapping out the PCCB rotors and Calipers on my 997.1 GT3 for the Stoptech Sport Trophy Big Brake Kit offered by GMG Racing.

It's the STR package that I'm referring to.
I would appreciate any feedback you may have regarding these.
thanks,
Dan

I used StopTech brakes (4-pot) on my E46 M3s. They were amazing. I am very happy ex customer of StopTech and all my formerly owned calipers are still in use by local track guys.
Nothing wrong with them if you put them (the 6-pot version obviously) on the GT3. But I don't think it would be that much of an upgrade. They only thing you could improve is to spec custom piston sizes to improve pad wear a little and maybe get a tiny bit more performance. That is very tricky to get right and not make it worse.

The adavntage is you do not have to remove rear caliper to change the pads
Not sure if they will flex like the stock front
You do not have to "modify" a pad to use it
You will have nice fresh yellow paint in lieu of burnt yellow after tracking

Just be aware that most GMG Racing 911s are running Brembo brakes, not Stop Tech (at the least the ones I keep seeing at races). Also, I'd suggest you compare pad sizes between Stop Tech product and OEM brakes on GT3. My understanding is that they run smaller pads, which is part of how they claim weight savings over OEM.

Agreed. In my book you either step up to the real deal (Brembo, AP or similar expensive option) or leave the stock brakes alone and just replace/upgrade rotors and pads as needed.

Yeah, you're right. But also remember that Brembo came out with the GTR kit before Stoptech had time to come out with STR. That also might be a factor for seeing Brembo kits more.
Well, in the end I'm a happy camper with my STR kit

The idea that the stock GT3 6 piston calipers can't or shouldn't be upgraded is an interesting notion. What if different calipers (such as the STR's) are lighter, stronger, flex less, and apply more torque than OEM? Also, what if changing pads were easier and you could also choose from a greater variety of pads? What if from going from PCCBs (never fade) to steel rotors you have concerns about brake fade and you find out that the STR kit is extremely fade resistant? Wouldn't all of those factors be considered an upgrade?
Also, according to GMG, the Stoptech STR Brake kit is equal to the performance of their Brembo GTR Brake kit in "back to back testing".
In additon to all of the above advantages, being equal to the Brembo GTR kit in performance should be considered an upgrade over stock 6 pistons and steel rotors , shouldn't it?

Speaking only for myself I was not suggesting that they could not or should not be replaced. From my personal (and therefore subjective) perspective I would ask myself what aspect of the OEM braking system is inadequate or underperforming ... rhetorically I personally could not justify the expense of replacing the OEM PCCB system as I am unable to detect any inherent lack that would motivate the expense ... I have no doubt that the StopTech and Bremo kits are incrementally better ... I just think that the OEM setup is pretty damn good to start with ... YMMV
I know that there are a few "drop in" steel replacements for the ceramic rotors, using the OEM calipers. Knowing that I'll miss my beloved PCCBs, I'm trying to make the switch to steel rotors with a minimal, if any, hit in performance in comparison to the stock PCCBs, and an "upgrade" to other steel optons.
