I know theres a lot of info about brake kits on the forum, and I've searched around a solid bit, but haven't found a bunch of info on where what exactly is the best street and track big brake package for a 996tt. Car makes a little over 700whp and is a pretty solid street/track car. I don't think there is a reason to run like a Brembo GT-R caliper because I feel like thats a bit overkill, but I feel like their other kits aren't really that great. Obviously the 996gt3 caliper is a solid option but I'm just looking for opinions.

Thanks!

 

in all honestly unless your running at the ragged edge the 4/4 setup is more than enough. its the pads and rotors that make the difference. if you must upgrade then the 997turbo setup is the clear choice both in stopping power and cost

 

^this^

 

The in between option is to use 997 turbo rotors but still use the 996tt calipers but with spacers and longer bolts. Many guys do this. 350 vs 330mm rotors. Not quite as much stopping power at with the 997 calipers but you gain some leverage (more braking power) and also more hear dissipation from the larger rotor. It's all 95% of street guys ever need

 

I would go with the 997s. Cheaper and easier to get parts along with good performance. Congrats on the top 10 also!

 

I often see people jump to upgrade to larger brake setups before the cheaper things like more cooling, better pads and fluid. And my take is the stock brakes with better pads and more cooling work well. But are not near as pretty as massive rotors and calipers. I consistently watch for deals on 997turbo and Gt3 calipers, but they just don't pop up often. So I will run stock with better ducts, pads and fluid until something pops up.

 

For street use, you simply can not out drive the stock brakes especially if you have good fluids, cooling, and pads. Install 997TT 350/350 rotors with caliper spacers and you will be in jail or kill someone long before the stock 4/4 brakes give out. For track use the 350/350 6/4 brakes will be more than adequate. Install the OEM 380/350s and never worry about brakes at the track again. For cars and coffee, the 380/350s are an absolute must of course...

 

This is a good note as well. I run rpf600 in all my cars, zero issues with fluid boiling. Also replacing old lines with new ones or as line makes a big difference. The larger gt3 brake deflectors are only 30 bucks.

 

I'll throw this out there. Porsche Motorsport used to use Castrol SRF as their fluid of choice. A few years ago they switched to Endless RF650. This is what is used by many teams in F1. Truly an fantastic fluid, relatively cheap at $45/500ml. I run this and only bleed brakes once a year now as opposed to every 5 or 6 track days.

Regarding brake lines, the OEM lines are very good and the same ones you'll find on Cup cars. They are a composite core encased with rubber construction as good or better that any "stainless steel" line on the aftermarket. I'm still on 15 year old OEMs. No need to reinvent the wheel.

For ducting, the $40 7GT3 street ducts are not any bigger than the small TT ducts as the GT3 benefits with additional cooling that get from the upper air duct that direct the radiator air to the rotors. The TT does not have these. Instead, get the 996Cup /GT2 front ducts (yes, pricey at $300 per pair) and the rear GT2 ducts at $175/pair.

 

Ive recently upgraded to 997T calipers from standard calipers with spacers ceramic pads and 350mm rotors the difference is like night and day.

My car is a daily driven street car with the occasional outing to the track, I agree I didnt need the extra braking power but damn Im so happy I have it.

If you can find yourself 997T calipers and rotors at a great price like I did buy them and enjoy that extra stopping power every bit as much as I am.

 

+1 as usual
The stock 6 GT2/3 brakes with proper pads/fluid hold up perfectly on hard/fast sessions without issue (of course 6TT also needs the GT2/Cup ducts, both .90 and .91 versions are good)...the PFC 08/11 combo on steels has 'unlimited' torque at any speed...
I personally like more rear bias so will be doing 997 rear (or all) calipers when my PFC pads are done

 

With my Brembo GT 350/350 6-4 setup i have been noticing some lack of performance at cars and coffee. I may move up to 380/350 to correct this.

Some calipers have a bridge in the middle. It provides increased stiffness for the same or less weight. Stiffness = better feel in the pedal. Something to think about.
