Definitely just pads and a good fluid flush with some hi-temp brake fluid like ATE Super Blue.
I used PBR metal masters for awhile; they were good for the money but if you don't mind squeaking and accelerated rotor wear get some track-acceptable hawk pads.

I cant really comment for economical as i got all of my stuff for free or near free. I got a set of 986 calipers(with decent pads) and radial mounts(that were originally for a 930 which need milling) and a set of used 951 turbo rotors which i am going to turn as they still have a lot of meat on them. I found some brake fluid at work and i am going to order some caliper bolts... Anyone have an idea where to get longer caliper bolts that will work with radial adaptors?
Over all I have about $34 dollars into the whole setup.
Going to do the install on sunday morning at a buddies house... i will take some pictures to document the journey.

One thing that should be clarified here is that the only early offset 15's that fit over 951 calipers are the phone dials (I haven't verified that myself so I am having to trust what others have said here). 15" Fuchs and 15" cookie cutters will not clear the 951 calipers. Neither will 16"x 6/7/8" 911 Fuchs. But 16" 951 Fuchs will clear the 951 calipers of course, as will 16"x9" 930 Fuchs.

The best upgrade I can think of now for a NA car is the Boxster S rotors and the Lexus 4 piston calipers.
It even works for early offset cars... providing you get 17" early offset wheels.

the best thing i ever did for my cars brakes that would put you through the windshield at 120mph repatably around a track are hawk hps brake pads and i got slotted rotors cheap from a place called r1 i found them on ebay so far have been great and as the pads brake in more and more and the hotter they get they only apply harder

Also, any idea on how the rotor size compares to 951 4-pot calipers? I've heard you might be able to use 986 Brake calipers on a 951 rotor (eg 986 and 951 rotors are the same size)...I was a little surprised when I heard that but haven't been able to verify the info anywhere. Does anyone know?
Thanks!

No no, this is completely different than the Big Reds or Blacks.
Its 2000's Boxster S rotors, and using Lexus LS430 calipers. You have to machine down the stock hubs a small amount so the Boxster S rotors will fit over top of them, then there's an adapter plate to make the caliper fit the stock mounting points, and presto! Big *** brakes.
(Really a LOT easier than it sounds.) I haven't done it yet, but there's a few on here that have, and they love it. I believe you must have 17in or larger wheels.

Interesting stuff. I always thought the Rennbay Wilwood kit looked like the easiest deal, even though I have all of the 86 951 parts necessary.
I have found the stock brakes more than adequate when properly maintained and using good fluid, lines, and pads. We get great track performance with Porterfield and Hawk pads. Stopping is never the issue in the NA cars, its gaining speed back again!

I agree 100%. There is no need to do anything to your brakes if your car is stock (other than routine maint.)
The only time you need more brake is when you get more power.... LS1 anyone?

If you have too much money burning a hole in your pocket, then go ahead and buy a BBK to show off but if you are on a budget and want the best stopping power for the track, then all you need to do is to change the front pads to Hawk Blue's and the rear pads to Hawk HP+, change your brake fluid to ATE Super Blue and if you'd like, you can also change the brake lines to stainless steel braided lines and you are good for racing.
The stock calipers and rotors are excellent and does not need upgrading, unless you just want that look.
