Default big red upgrade vs stoptechs?

Curious for people's feedback here.

I assumed I was going to do the traditional big red brake upgrade on my C2. Front 993 turbo calipers, rear 992 C2 calipers (same size as 964, just different piston size), floating rotors, pads, stainless lines. Unless you pay a premium, whatever you buy is going to need a rebuild and paint. Maybe you could do this for under $2k with standard rotors, but floating ones appear to be about $1k/axle.

But as I've done my research, I realize that a new stoptech front axle kit can be had for about $2500. This includes their ST-40 caliper, floating 355mm rotors, lines, and pads. Their front kit is designed to work with stock rears.

I've used Stoptech on previous track cars. But I don't think I've seen anyone using them on a 964. Is there a reason people don't consider the stoptechs when they are doing this upgrade? There used to be a stigma about them not being as good as brembos, but it seems other car brand crowds have gotten over this. Is this the issue here or is it something else?

Big reds on a turbo are great brakes but on a C2 they are amazing and in reality perhaps a little over braked. A 355 disc setup would certainly be over braked imo and adds unnecessary weight.

You just like posting pictures of your new blue car. :P

As for weight, I'd be willing to bet that a 355mm Stoptech kit with the standard floating rotor is lighter than the 322mm big red kit with standard rotors. but beyond weight, this kit is brand new vs 20 year old referb stuff. its got to be worth considering right?

I love big brakes (and I cannot lie) but I think my 1992 C2 brakes are enough.

Rather spend money on better pads, fluids, etc.

My thought process:
I did the math on a fully rebuilt/refurbished set of big reds f/r
compared to a new set of Brembo f/r with modern caliper design, modern rotor/aluminum hat design
the price was not terribly different
so I went with the brembo setup (993 front, 964 rear you can see details in my build thread)
No regrets and car has massive braking power for the wide/sticky tires I use

Sorry for the thread hijack... Spyrex, where did you source the Brembo rotors with the aluminum hats? I've been running early 964 Turbo (non-monoblock) Big Reds for years front and rear - and yes, love them - and it's close to rotor replacement time, would like to lighten some of the unsprung, whirly bits.

BBI Sourced for me from Brembo / Race Technologies:

Brembo GT Kit, 993 - slotted, red, TS20 pads - 1M2.8001A - Front
Brembo GT Kit, 964 - slotted, red, TS20 pads - 2C2.6017A - Rear

Keep in mind I'm using 993 front end/uprights.

I am also looking for a big brake kit front and rear for my 964 Turbo. Thoughts?

I also run the Brembo GT kit, 964 front and rear. Love the setup, never had brakes that work so well. I don't track my car so I can't speak to their performance on that, definitely more than I need for a street car but they sure look good, lol.

The one drawback to running 355's, you can no longer run 17's.

I wonder what the caliper bore sizing is on the stoptech units. If they advertise to be compatible with stock rears then maybe they are smaller bores and would not require a larger master/993 booster.

Is is everyone going to the 993master/booster when going with big brakes?
